| 3. An open source geo-transformation library for data custodians.[[Media:03_knudsen.pdf‎]]
|| The KMStrlib geo-transformation library, which has been in active use and development since the 1960s at KMS (National Survey and Cadastre, Denmark), is now finally being released under an open source licence.

KMStrlib provides a unified interface to a large number of cartographic projections, and geophysical transformations (including change of vertical and horizontal datums and epochs).

Due to KMS's role as a long term geodata custodian, care has been taken to ensure that the transformations implemented are two way symmetric (to the extent possible: some transformations are inherently vaguely defined, and must be implemented by stochastic predictions, rather than projections). This has led to the adoption of a technique of dual self-checking transformations, effectively doing a roundtrip "forward-inverse" operation for all library calls. While elaborate, this ensures that uncaught implementation blunders, and asymmetric singularities are diagnosed and reported. This is essential for long term (multiple century scale) geodata interoperability.

The poster presentation will include schematic details of the dual self-checking procedure, and illustrate the characteristics of the KMStrlib implementation of a fast, highly precise transverse mercator projection, remaining accurate at the 0.03 mm level even at distances 7500 km from the central meridian.

| 4. Quality control of digital elevation models.
[[Media:04_knudsen.pdf‎]]
|| In this poster presentation, we describe how the PINGPONG program (FOSS distributed under the GPL) has been used to implement a quality control procedure for laser scanned DEMs. The approach used is independent of navigational (GPS/INS) data and ground control points.

Fundamentally, PINGPONG is a high speed gridding program for scattered geodata. It uses a simple, but efficient, data management technique to speed up the gridding procedure.

The speed of PINGPONG makes it feasible to include a large amount of gridding in our quality control procedure, even for national scale datasets (in our case involving in the order of 20 billion data points), so the procedure is based on analysis of the local difference of a digital surface model, and a digital terrain model.

Effectively, this means that we are generating two interim elevation models in order to test one point cloud for its suitability for generating a final model. While this may seem somewhat extravagant, experience shows that it is actually both useful and efficient.

| 5. INSPIRE compliant geoservices for topographic databases of the Lombardy Region in Italy.
|| Aim of the work is the implementation of geoservices compliant with the European INSPIRE Directive for distributing Lombardy Region geotopographic databases at scale 1:2000.
The services are based on OpenGIS Catalogue Service Implementation Specification (CS-W 2.0.1) and OpenGIS Web Map Service (WMS 1.3.0) Implementation Specification as required by the Directive itself. They were implemented with Open Source Software: UMN Mapserver for WMS service and Geonetwork for metadata handling (CS-W).
Test data used for the prototype are compliant with the Standard for modelling geographic data recently approved by the Lombardy Region (february 2008).
The infrastructure is freely available for all territorial Authorities having such a kind of geotopographic database. A website with a demo version is already online (http://ows.como.polimi.it) and will be shown if an internet connection is available.

| 6. Electronic Tag Data Visualisation
|| In 1981 CSIRO Marine and Atmospheric Research (CMAR) began development of a database to house data on conventional tagging of marine fishes. Since that time CMAR’s tagging projects have expanded and incorporated a wide range of tags from the simple conventional through to the latest electronic tags, and have began tagging marine mammals and birds. The amount of data being generated has vastly increased since 1981. CMAR has promoted a centralisation of tag data to ensure data are widely accessible, secured against loss, and to reduce redundancy amongst projects. One criticism of this approach has been a difficulty in data access within and across sites. Through the Electronic Tag Support Systems project CMAR has developed a web portal, using SVG, to the tagging database allowing users to browse through the electronic tag data and easily extract data of interest for further analysis. Tag tracks are displayed on an interactive map and archival data displayed in interactive graphs.

| 7. OldMapsOnline.org: Open Source & Online Tools for Old Maps
|| OldMapsOnline.org is a research project targeted to the software development specialized to old map collections. We are designing online tools for collaborative georeferencing, annotation, 3D visualization, accuracy analysis and geometadata speciﬁcation.

We provide free software and tutorials for online publishing of your scanned historical maps. We have developed IIPImage JPEG2000 Image Server: open source server software for fast delivery of the ultra high resolution raster imagery directly from your master scans in formats like JPEG2000 or TIFF. This software can be used for free on your servers for the image publishing. You can also publish your maps as pre-rendered tiles (zoomify) without any extensive configuration of your webserver. There is a whole collection of attractive pan&zoom viewers for the visualization of your scanned maps in your web sites - all viewers are compatible with both publishing techniques (JPEG2000/TIFF or prerendered tiles) - and they are mostly available including the source code, so you can easily customize them according your needs.

Once your maps are online you can use our web-based tools to georeference and visualize them in 3D with Google Earth web browser plugin. Your scanned maps can simply overlay each other as well as the popular interactive base maps like OpenStreetMap, Bing, Yahoo or Google Maps. You can even analyze their cartometric accuracy - all of this within the web browser.

Our project is in progress but we have already published several software tools and we have prototypes for the complete workflow. More info at http://www.oldmapsonline.org/

|8. geo-spatial.org: The Reference Point for the Romanian FOSS4G community
||A geospatial portal is a human interface to a collection of online geospatial information resources, including data sets and services (OGC, 2004). geo-spatial.org is a collaborative effort by and for the Romanian community to facilitate the sharing of geospatial knowledge and the discovery and publishing of free geographic datasets and maps. It was created by a small team of young scientists as an attempt to overcome the Romanian specific geospatial dysfunctions.
Anyone can make a contribution by submitting articles or datasets for publication, adding comments to the existing articles, join the discussion on the mailing list or users forum.
The content is managed by Textpattern, a powerful and flexible, open source content management application. For supplementary, specific functionality, custom modules were built. Other free applications are providing server-side functionality: MySQL (relational database management system), PHP, Python, Java (server-side scripting languages), Apache (webserver), Tomcat (servlet container), phpMyAdmin, phpPgAdmin (web clients for database management). For geospatial data processing and management, top open source applications were also integrated in the website: Mapbender (geodata management using OGC OWS architectures), PostGIS (is an extension for the PostgreSQL enterprise relational database, used to store the geospatial data), GeoNetwork Opensource (a standards based catalog application to manage spatially referenced resources), Geoserver (a standard compliant geospatial server, used to create specific services like WMS, WFS, WCS), OpenLayers (a pure JavaScript library for displaying map data), GeoWebCache (provides a Java-based WMS/TMS server, with pluggable caching mechanisms and rendering backends), Mapnik (render the base map), GDAL/OGR (used inside chained scripts for data conversion and reprojection).
The website is divided in several functional sections. In each section, the information is placed in predefined categories and sub-categories. Most of the sections contains written materials:
- Articles - theoretical essays on geospatial topics;
- Tutorials - materials indented to teach the user, in a step by step manner, how to work with certain datasets, software, technique etc;
- Reviews - reviews for geospatial datasets, cartographic products, software, articles, books;
- Links - collections of references to other online resources;
- Blog - a non conventional section for publishing thoughts, ideas, findings etc.
The content of these sections can be accessed quickly via RSS and ATOM feeds.
The Download section contains categories for all kind of geospatial data (digital elevation models, processed satellite images, vector data: communication networks, localities, hydrographical networks, contour lines, points of interest etc.) at different scales and spatial extend. Other categories contain documents (PhD thesis, scanned books & articles), old maps, software.
The website interface was carefully designed, respecting the existing W3C (World Wide Web Consortium) standards and separating the structure from the presentation by using strict XHTML markup and CSS (Cascade Style Sheets). New web technologies, like AJAX (Asynchronous JavaScript and XML), were also used to increase the interactivity. The goal was to obtain a simple, friendly and accessible environment for geospatial data and knowledge publication.

|9. WEBGIS for the tangible and intangible assets of a public agency
||The ever-growing dissemination of Geographic Information Systems (GIS) in the Public Administration highlights the potential and effectiveness of this method of approach to the management of spatial databases. This is applicable both to the tangible and intangible assets of a public agency. An important moment for the sharing and communication of the data in a GIS is their publication and dissemination on the Internet through WebGIS and geoservices.
On the basis of these considerations, we chose to design and build a WebGIS for the management, use and protection of all the tangible and intangible heritage of the municipality of Orgosolo, recorded and documented in a project by the “Centre for monitoring and documenting the local traditions and skills”. The WebGIS was built using only free / open-source software, both for the advantages in terms of customization and interoperability, and in order to limit the building and management costs.
The first part of the work regarded building the GIS. The used software was gvSIG ( Conselleria de Infraestructuras y Transporte Valencia). The database was built in MySQL and then connected with gvSIG.
The GIS included the data on the urban architecture and murals regarding the tangible heritage, and on the traditional skills for the intangible heritage.
The next step was implementing the GIS in a WebGIS system thusly structured:
• Apache Web Server
• Geoserver WebGIS
Geoserver (http://docs.codehaus.org/display/GEOS/Home) was chosen due to being an open source (GPL) WebGIS server written in Java and supporting the OGC (Open Geospatial Consortium) standards, such as the WFS, WMS and WCS geoservice protocols

|10. Northern Queensland Wildfire Mitigation Project - Improving Community Safety Through Informed Hazard Reduction
||The Northern Queensland Wildfire Mitigation Project includes a website with online mapping and a data warehouse, available to all agencies involved in the management of wildfire in northern Queensland. Agencies can access more than 140 pre-contructed fire district maps and have access to over 60 mapping layers in the online tools, provided at no cost to the user.
The project, established by Atherton Tablelands Geographic Information Systems (ATGIS), with assistance from many stakeholder agencies, took little more than 12 months to complete and was officially launched in June 2008.

The online mapping tools take advantage of free and open source software including: FreeBSD, PostgreSQL, PostGIS, Apache Webserver, UMN MapServer & GoogleMaps API, and provide users with a rich experience, enabling them to digitise and attribute objects online, and either submit them for QA and inclusion in master datasets, or in emergencies, publish data to all users immediately. Users can also submit entire GIS datasets and other digital files as an input to the regular collation of the key fire infrastructure datasets, maintained as part of this project.

The website contains multiple menu items:
- Help - animated help files and user guides to assist new users of the website;
- News - articles identifying improvements to the website and freshly published data;
- Create maps - online tools for map creation, including online digitising tools;
- Resources - collections of other resources available for download, including documents, maps and GIS datasets in multiple formats.
- Download maps sub menu - collections of existing maps, available for download as PDF or JPG, with the spatial extents of each map presented as objects in a Google map window;
- File Exchange - A facility for publishing documents to the website and for uploading datasets and information for consumption by other stakeholders
- Submit Feedback - An online form for specifying bugs, data issues and suggested improvements, formatted to prompt users to describe what they were doing, what they expected as a result and what they observed.

|11. Drift-X WPS: An atmopsheric dispersion simulation Web-GIS platform
||Our past research treated the problem of integrating Drift-X, a Gaussian based atmospheric dispersion model within a desktop GIS framework. A dedicated pesticide spray drift model was implemeted within Quantum GIS using its Python bindings capabilities and the results were presented at FOSS4G2008.

The present work aims now to adapt this model to Web-GIS platform using the ZOO Open WPS Platform . WPS implementation is aimed in order to automate the model setup and to perform on-line simulations. The main idea is to use WPS service that are inbuilt in the ZOO Kernel that can respond with XML document to the Getcapabilities, DescribeProcess and ExecProcess requests sent from the client browser. Input parameters needed by the model are sent to the ZOO server from an advanced OpenLayers client.

Subsequently, the Drift-X WPS module processes the DEM layer for the given extent, deliver it to the model with other user-defined parameters, run the model and then send the results to a WMS MapServer installation in a standard GIS format. The results are finally tiled by MapServer and potrayed within the OpenLayers client. The present WPS implementation will be useful for better agricultural practices by minimizing pesitiside use. Further, the ZOO Open WPS Platform implemented in this research could be enhanced with Sensor Network functionality to support precision farming.

|12. Application of SWAT for Sediment Yield Estimation in a Semi-arid Mountainous Basin
||The advanced SWAT (Soil and Water Assessment Tool) model is based on hydrologic process and needs to be calibrated and validated prior to its application. This paper presents a case study conducted in Chaohe river upstream to verify the applicability of SWAT for predicting sediment yields in a semi-arid mountainous basin, in which the parameterization of HRU is particularly carried out to reflect the impact of rugged topography on hydrologic process in comparison of the default computation methods. With the historical gauge records, the above modification was well tested in the study area. The monthly measured runoff and sediment yields at Dage guage during the period 1985-1987 was used to calibrate the model while data from 1988 to 1990 was used for model validation. The simulation results revealed that the SWAT with the above improvement could be applied in a rugged mountainous region for erosion control and watershed management.

|13. Use of Open Source Geospatial Software within the Remote Sensing Centre, QLD.
||The Remote Sensing Centre (RSC), within the Queensland Department of Environment and Resource Management (DERM), is a leading group within remote sensing in Australia. The RSC currently uses a combination of various open source software to meet much of its geospatial processing requirements. Indeed, the systems in place at the centre have been largely developed around open source tools, which is unusual for a government agency. Principal software includes: PostGIS, QGIS, GDAL/OGR, Python and R. This poster discusses the systems in place and our experience with their implementation and use.

|14. Developing a 3D Indoor Pedestrian Simulator using a spatial DBMS.
||Most crowd simulation models for pedestrian dynamics are based on analytical approach using experimental settings without being related to real world data. In order for the models to be adapted to real world applications such as fire evacuation, some technical aspects first must be resolved. First, the base data should represent the 3D indoor model which contains semantic information of each space. Second, in order to communicate with the indoor localization sensors to capture the real time pedestrians and to store the simulation results for later uses, the data should be in a DBMS instead of files. The purpose of this paper is two folds. One is to suggest a DBMS-based 3D modeling approach for pedestrian simulations. The other is to improve the existing floor field based pedestrian model by modifying the dynamic field. We illustrated the data construction processes and simulations using the PostGIS DBMS and the enhanced pedestrian model.

|15. Developing a Campus Spatial Information System using the PostGIS.
||Most 3D models found in the literature focus on theoretical topology for exterior volumes. However, implementing a full topology for the indoor spaces is less practical due to the computational complexity and current spatial DBMSs do not support explicit 3D topological relations between geometric components. In this study, an alternative method to build a 3D indoor model with less complexity using a spatial DBMS is suggested. Focusing on the fact that semantic attributes can be stored on the floor surface, we suggest a multi-layered 3D model for indoor spaces. We show the process to build the proposed model in the PostGIS. And, then, as an example application, we illustrate the process to build and run a campus building information system.

|16. Parallel processing, some GIS applications and their performances on IBM Cell Broadband engine and Intel multicore platforms
||Parallel processing has been established as the best way to scale performance in the near future. Most of the GIS algorithms are amenable to parallel processing. We present herein some preliminary results from parallelization of common GIS modules on IBM Cell Broadband Engine, which forms the core of playstation3. We also show results of our OpenMP implementation, and some programming practices necessary for large scale applications.

|17. Automated Segmentation and Generalisation of Raster Imagery
||This study reviews past and current research activity in the area of generalisation of spatial data and presents a new methodological framework for segmentation and generalisation of raster data. In order to overcome drawbacks associated with supervised classification and generalisation of raster data, an Interactive Automated Segmentation and Raster Generalisation Framework (IASRGF) was developed and tested. Test results of the IASGRF shows that all objects derived from the generalisation of landuse data over Canberra, Australia, were well classified and mapped. The error assessment indicates that the percentile classification accuracy is 85.5%, whereas the commission error is relatively high (38.5%). More importantly, the maximum likelihood classifier using training sites and associated ground truth data suggests that the Kappa index is 0.798, which can be interpreted as a reliable and satisfactory classification result. In order to further enhance supervised classification, a post-classification was carried out. As a result, this extra process improved the overall classification accuracy.

|18. A Knowledge-Based Algorithm for Generalization of Line and Polyline Data
||Current map production systems provide reasonably complex tools and procedural cartographic protocols, however, cartographers’ interactions are essential for selecting information, symbolizing features, maintaining topological relationships, and visualizing graphical conflicts. Although an efficient generalization technique would improve the graphical quality and legibility of maps, existing techniques use an “ill-structured” approach because it is hard to devise an algorithm to solve the problem. On the other hand, expert systems use a collection of “rules of thumb” that are mainly heuristics methods or principles for decision making. It is an alternative solution to the aforementioned problem. In this research, “Generalization Expert System (GES)”: a knowledge-based solution is developed. Key steps undertaken in building GES and its components are presented here. GES is developed in Java and Python for the delivery of simplified spatial data. Its capabilities are demonstrated in a case study through simplifying roads, native vegetation and elevation data to derive 1:500,000 scale from the source maps at 1:250,000 scale over Canberra, Australian Capital Territory, Australia. Although a number of advanced applications have been developed with high technical skills, GES has a simple and user-friendly GUI that can benefit users with lesser technical skills and knowledge of spatial data management.

| 7. OldMapsOnline.org: Open Source & Online Tools for Old Maps
|| OldMapsOnline.org is a research project targeted to the software development specialized to old map collections. We are designing online tools for collaborative georeferencing, annotation, 3D visualization, accuracy analysis and geometadata speciﬁcation.

We provide free software and tutorials for online publishing of your scanned historical maps. We have developed IIPImage JPEG2000 Image Server: open source server software for fast delivery of the ultra high resolution raster imagery directly from your master scans in formats like JPEG2000 or TIFF. This software can be used for free on your servers for the image publishing. You can also publish your maps as pre-rendered tiles (zoomify) without any extensive configuration of your webserver. There is a whole collection of attractive pan&zoom viewers for the visualization of your scanned maps in your web sites - all viewers are compatible with both publishing techniques (JPEG2000/TIFF or prerendered tiles) - and they are mostly available including the source code, so you can easily customize them according your needs.

Once your maps are online you can use our web-based tools to georeference and visualize them in 3D with Google Earth web browser plugin. Your scanned maps can simply overlay each other as well as the popular interactive base maps like OpenStreetMap, Bing, Yahoo or Google Maps. You can even analyze their cartometric accuracy - all of this within the web browser.

Our project is in progress but we have already published several software tools and we have prototypes for the complete workflow. More info at http://www.oldmapsonline.org/

|8. geo-spatial.org: The Reference Point for the Romanian FOSS4G community
||A geospatial portal is a human interface to a collection of online geospatial information resources, including data sets and services (OGC, 2004). geo-spatial.org is a collaborative effort by and for the Romanian community to facilitate the sharing of geospatial knowledge and the discovery and publishing of free geographic datasets and maps. It was created by a small team of young scientists as an attempt to overcome the Romanian specific geospatial dysfunctions.
Anyone can make a contribution by submitting articles or datasets for publication, adding comments to the existing articles, join the discussion on the mailing list or users forum.
The content is managed by Textpattern, a powerful and flexible, open source content management application. For supplementary, specific functionality, custom modules were built. Other free applications are providing server-side functionality: MySQL (relational database management system), PHP, Python, Java (server-side scripting languages), Apache (webserver), Tomcat (servlet container), phpMyAdmin, phpPgAdmin (web clients for database management). For geospatial data processing and management, top open source applications were also integrated in the website: Mapbender (geodata management using OGC OWS architectures), PostGIS (is an extension for the PostgreSQL enterprise relational database, used to store the geospatial data), GeoNetwork Opensource (a standards based catalog application to manage spatially referenced resources), Geoserver (a standard compliant geospatial server, used to create specific services like WMS, WFS, WCS), OpenLayers (a pure JavaScript library for displaying map data), GeoWebCache (provides a Java-based WMS/TMS server, with pluggable caching mechanisms and rendering backends), Mapnik (render the base map), GDAL/OGR (used inside chained scripts for data conversion and reprojection).
The website is divided in several functional sections. In each section, the information is placed in predefined categories and sub-categories. Most of the sections contains written materials:
- Articles - theoretical essays on geospatial topics;
- Tutorials - materials indented to teach the user, in a step by step manner, how to work with certain datasets, software, technique etc;
- Reviews - reviews for geospatial datasets, cartographic products, software, articles, books;
- Links - collections of references to other online resources;
- Blog - a non conventional section for publishing thoughts, ideas, findings etc.
The content of these sections can be accessed quickly via RSS and ATOM feeds.
The Download section contains categories for all kind of geospatial data (digital elevation models, processed satellite images, vector data: communication networks, localities, hydrographical networks, contour lines, points of interest etc.) at different scales and spatial extend. Other categories contain documents (PhD thesis, scanned books & articles), old maps, software.
The website interface was carefully designed, respecting the existing W3C (World Wide Web Consortium) standards and separating the structure from the presentation by using strict XHTML markup and CSS (Cascade Style Sheets). New web technologies, like AJAX (Asynchronous JavaScript and XML), were also used to increase the interactivity. The goal was to obtain a simple, friendly and accessible environment for geospatial data and knowledge publication.

||The ever-growing dissemination of Geographic Information Systems (GIS) in the Public Administration highlights the potential and effectiveness of this method of approach to the management of spatial databases. This is applicable both to the tangible and intangible assets of a public agency. An important moment for the sharing and communication of the data in a GIS is their publication and dissemination on the Internet through WebGIS and geoservices.
On the basis of these considerations, we chose to design and build a WebGIS for the management, use and protection of all the tangible and intangible heritage of the municipality of Orgosolo, recorded and documented in a project by the “Centre for monitoring and documenting the local traditions and skills”. The WebGIS was built using only free / open-source software, both for the advantages in terms of customization and interoperability, and in order to limit the building and management costs.
The first part of the work regarded building the GIS. The used software was gvSIG ( Conselleria de Infraestructuras y Transporte Valencia). The database was built in MySQL and then connected with gvSIG.
The GIS included the data on the urban architecture and murals regarding the tangible heritage, and on the traditional skills for the intangible heritage.
The next step was implementing the GIS in a WebGIS system thusly structured:
• Apache Web Server
• Geoserver WebGIS
Geoserver (http://docs.codehaus.org/display/GEOS/Home) was chosen due to being an open source (GPL) WebGIS server written in Java and supporting the OGC (Open Geospatial Consortium) standards, such as the WFS, WMS and WCS geoservice protocols

|10. Northern Queensland Wildfire Mitigation Project - Improving Community Safety Through Informed Hazard Reduction
||The Northern Queensland Wildfire Mitigation Project includes a website with online mapping and a data warehouse, available to all agencies involved in the management of wildfire in northern Queensland. Agencies can access more than 140 pre-contructed fire district maps and have access to over 60 mapping layers in the online tools, provided at no cost to the user.
The project, established by Atherton Tablelands Geographic Information Systems (ATGIS), with assistance from many stakeholder agencies, took little more than 12 months to complete and was officially launched in June 2008.

The online mapping tools take advantage of free and open source software including: FreeBSD, PostgreSQL, PostGIS, Apache Webserver, UMN MapServer & GoogleMaps API, and provide users with a rich experience, enabling them to digitise and attribute objects online, and either submit them for QA and inclusion in master datasets, or in emergencies, publish data to all users immediately. Users can also submit entire GIS datasets and other digital files as an input to the regular collation of the key fire infrastructure datasets, maintained as part of this project.

The website contains multiple menu items:
- Help - animated help files and user guides to assist new users of the website;
- News - articles identifying improvements to the website and freshly published data;
- Create maps - online tools for map creation, including online digitising tools;
- Resources - collections of other resources available for download, including documents, maps and GIS datasets in multiple formats.
- Download maps sub menu - collections of existing maps, available for download as PDF or JPG, with the spatial extents of each map presented as objects in a Google map window;
- File Exchange - A facility for publishing documents to the website and for uploading datasets and information for consumption by other stakeholders
- Submit Feedback - An online form for specifying bugs, data issues and suggested improvements, formatted to prompt users to describe what they were doing, what they expected as a result and what they observed.

|11. Drift-X WPS: An atmopsheric dispersion simulation Web-GIS platform
||Our past research treated the problem of integrating Drift-X, a Gaussian based atmospheric dispersion model within a desktop GIS framework. A dedicated pesticide spray drift model was implemeted within Quantum GIS using its Python bindings capabilities and the results were presented at FOSS4G2008.

The present work aims now to adapt this model to Web-GIS platform using the ZOO Open WPS Platform . WPS implementation is aimed in order to automate the model setup and to perform on-line simulations. The main idea is to use WPS service that are inbuilt in the ZOO Kernel that can respond with XML document to the Getcapabilities, DescribeProcess and ExecProcess requests sent from the client browser. Input parameters needed by the model are sent to the ZOO server from an advanced OpenLayers client.

Subsequently, the Drift-X WPS module processes the DEM layer for the given extent, deliver it to the model with other user-defined parameters, run the model and then send the results to a WMS MapServer installation in a standard GIS format. The results are finally tiled by MapServer and potrayed within the OpenLayers client. The present WPS implementation will be useful for better agricultural practices by minimizing pesitiside use. Further, the ZOO Open WPS Platform implemented in this research could be enhanced with Sensor Network functionality to support precision farming.

|12. Application of SWAT for Sediment Yield Estimation in a Semi-arid Mountainous Basin
||The advanced SWAT (Soil and Water Assessment Tool) model is based on hydrologic process and needs to be calibrated and validated prior to its application. This paper presents a case study conducted in Chaohe river upstream to verify the applicability of SWAT for predicting sediment yields in a semi-arid mountainous basin, in which the parameterization of HRU is particularly carried out to reflect the impact of rugged topography on hydrologic process in comparison of the default computation methods. With the historical gauge records, the above modification was well tested in the study area. The monthly measured runoff and sediment yields at Dage guage during the period 1985-1987 was used to calibrate the model while data from 1988 to 1990 was used for model validation. The simulation results revealed that the SWAT with the above improvement could be applied in a rugged mountainous region for erosion control and watershed management.

|13. Use of Open Source Geospatial Software within the Remote Sensing Centre, QLD.
||The Remote Sensing Centre (RSC), within the Queensland Department of Environment and Resource Management (DERM), is a leading group within remote sensing in Australia. The RSC currently uses a combination of various open source software to meet much of its geospatial processing requirements. Indeed, the systems in place at the centre have been largely developed around open source tools, which is unusual for a government agency. Principal software includes: PostGIS, QGIS, GDAL/OGR, Python and R. This poster discusses the systems in place and our experience with their implementation and use.

|14. Developing a 3D Indoor Pedestrian Simulator using a spatial DBMS.
||Most crowd simulation models for pedestrian dynamics are based on analytical approach using experimental settings without being related to real world data. In order for the models to be adapted to real world applications such as fire evacuation, some technical aspects first must be resolved. First, the base data should represent the 3D indoor model which contains semantic information of each space. Second, in order to communicate with the indoor localization sensors to capture the real time pedestrians and to store the simulation results for later uses, the data should be in a DBMS instead of files. The purpose of this paper is two folds. One is to suggest a DBMS-based 3D modeling approach for pedestrian simulations. The other is to improve the existing floor field based pedestrian model by modifying the dynamic field. We illustrated the data construction processes and simulations using the PostGIS DBMS and the enhanced pedestrian model.

|15. Developing a Campus Spatial Information System using the PostGIS.
||Most 3D models found in the literature focus on theoretical topology for exterior volumes. However, implementing a full topology for the indoor spaces is less practical due to the computational complexity and current spatial DBMSs do not support explicit 3D topological relations between geometric components. In this study, an alternative method to build a 3D indoor model with less complexity using a spatial DBMS is suggested. Focusing on the fact that semantic attributes can be stored on the floor surface, we suggest a multi-layered 3D model for indoor spaces. We show the process to build the proposed model in the PostGIS. And, then, as an example application, we illustrate the process to build and run a campus building information system.

|17. Automated Segmentation and Generalisation of Raster Imagery
||This study reviews past and current research activity in the area of generalisation of spatial data and presents a new methodological framework for segmentation and generalisation of raster data. In order to overcome drawbacks associated with supervised classification and generalisation of raster data, an Interactive Automated Segmentation and Raster Generalisation Framework (IASRGF) was developed and tested. Test results of the IASGRF shows that all objects derived from the generalisation of landuse data over Canberra, Australia, were well classified and mapped. The error assessment indicates that the percentile classification accuracy is 85.5%, whereas the commission error is relatively high (38.5%). More importantly, the maximum likelihood classifier using training sites and associated ground truth data suggests that the Kappa index is 0.798, which can be interpreted as a reliable and satisfactory classification result. In order to further enhance supervised classification, a post-classification was carried out. As a result, this extra process improved the overall classification accuracy.

|18. A Knowledge-Based Algorithm for Generalization of Line and Polyline Data
||Current map production systems provide reasonably complex tools and procedural cartographic protocols, however, cartographers’ interactions are essential for selecting information, symbolizing features, maintaining topological relationships, and visualizing graphical conflicts. Although an efficient generalization technique would improve the graphical quality and legibility of maps, existing techniques use an “ill-structured” approach because it is hard to devise an algorithm to solve the problem. On the other hand, expert systems use a collection of “rules of thumb” that are mainly heuristics methods or principles for decision making. It is an alternative solution to the aforementioned problem. In this research, “Generalization Expert System (GES)”: a knowledge-based solution is developed. Key steps undertaken in building GES and its components are presented here. GES is developed in Java and Python for the delivery of simplified spatial data. Its capabilities are demonstrated in a case study through simplifying roads, native vegetation and elevation data to derive 1:500,000 scale from the source maps at 1:250,000 scale over Canberra, Australian Capital Territory, Australia. Although a number of advanced applications have been developed with high technical skills, GES has a simple and user-friendly GUI that can benefit users with lesser technical skills and knowledge of spatial data management.

| 3. An open source geo-transformation library for data custodians.
|| The KMStrlib geo-transformation library, which has been in active use and development since the 1960s at KMS (National Survey and Cadastre, Denmark), is now finally being released under an open source licence.

KMStrlib provides a unified interface to a large number of cartographic projections, and geophysical transformations (including change of vertical and horizontal datums and epochs).

Due to KMS's role as a long term geodata custodian, care has been taken to ensure that the transformations implemented are two way symmetric (to the extent possible: some transformations are inherently vaguely defined, and must be implemented by stochastic predictions, rather than projections). This has led to the adoption of a technique of dual self-checking transformations, effectively doing a roundtrip "forward-inverse" operation for all library calls. While elaborate, this ensures that uncaught implementation blunders, and asymmetric singularities are diagnosed and reported. This is essential for long term (multiple century scale) geodata interoperability.

The poster presentation will include schematic details of the dual self-checking procedure, and illustrate the characteristics of the KMStrlib implementation of a fast, highly precise transverse mercator projection, remaining accurate at the 0.03 mm level even at distances 7500 km from the central meridian.

| 4. Quality control of digital elevation models.
|| In this poster presentation, we describe how the PINGPONG program (FOSS distributed under the GPL) has been used to implement a quality control procedure for laser scanned DEMs. The approach used is independent of navigational (GPS/INS) data and ground control points.

Fundamentally, PINGPONG is a high speed gridding program for scattered geodata. It uses a simple, but efficient, data management technique to speed up the gridding procedure.

The speed of PINGPONG makes it feasible to include a large amount of gridding in our quality control procedure, even for national scale datasets (in our case involving in the order of 20 billion data points), so the procedure is based on analysis of the local difference of a digital surface model, and a digital terrain model.

Effectively, this means that we are generating two interim elevation models in order to test one point cloud for its suitability for generating a final model. While this may seem somewhat extravagant, experience shows that it is actually both useful and efficient.

| 5. INSPIRE compliant geoservices for topographic databases of the Lombardy Region in Italy.
|| Aim of the work is the implementation of geoservices compliant with the European INSPIRE Directive for distributing Lombardy Region geotopographic databases at scale 1:2000.
The services are based on OpenGIS Catalogue Service Implementation Specification (CS-W 2.0.1) and OpenGIS Web Map Service (WMS 1.3.0) Implementation Specification as required by the Directive itself. They were implemented with Open Source Software: UMN Mapserver for WMS service and Geonetwork for metadata handling (CS-W).
Test data used for the prototype are compliant with the Standard for modelling geographic data recently approved by the Lombardy Region (february 2008).
The infrastructure is freely available for all territorial Authorities having such a kind of geotopographic database. A website with a demo version is already online (http://ows.como.polimi.it) and will be shown if an internet connection is available.

| 6. Electronic Tag Data Visualisation
|| In 1981 CSIRO Marine and Atmospheric Research (CMAR) began development of a database to house data on conventional tagging of marine fishes. Since that time CMAR’s tagging projects have expanded and incorporated a wide range of tags from the simple conventional through to the latest electronic tags, and have began tagging marine mammals and birds. The amount of data being generated has vastly increased since 1981. CMAR has promoted a centralisation of tag data to ensure data are widely accessible, secured against loss, and to reduce redundancy amongst projects. One criticism of this approach has been a difficulty in data access within and across sites. Through the Electronic Tag Support Systems project CMAR has developed a web portal, using SVG, to the tagging database allowing users to browse through the electronic tag data and easily extract data of interest for further analysis. Tag tracks are displayed on an interactive map and archival data displayed in interactive graphs.

|11. Drift-X WPS: An atmopsheric dispersion simulation Web-GIS platform
||Our past research treated the problem of integrating Drift-X, a Gaussian based atmospheric dispersion model within a desktop GIS framework. A dedicated pesticide spray drift model was implemeted within Quantum GIS using its Python bindings capabilities and the results were presented at FOSS4G2008.

The present work aims now to adapt this model to Web-GIS platform using the ZOO Open WPS Platform . WPS implementation is aimed in order to automate the model setup and to perform on-line simulations. The main idea is to use WPS service that are inbuilt in the ZOO Kernel that can respond with XML document to the Getcapabilities, DescribeProcess and ExecProcess requests sent from the client browser. Input parameters needed by the model are sent to the ZOO server from an advanced OpenLayers client.

Subsequently, the Drift-X WPS module processes the DEM layer for the given extent, deliver it to the model with other user-defined parameters, run the model and then send the results to a WMS MapServer installation in a standard GIS format. The results are finally tiled by MapServer and potrayed within the OpenLayers client. The present WPS implementation will be useful for better agricultural practices by minimizing pesitiside use. Further, the ZOO Open WPS Platform implemented in this research could be enhanced with Sensor Network functionality to support precision farming.

|12. Application of SWAT for Sediment Yield Estimation in a Semi-arid Mountainous Basin
||The advanced SWAT (Soil and Water Assessment Tool) model is based on hydrologic process and needs to be calibrated and validated prior to its application. This paper presents a case study conducted in Chaohe river upstream to verify the applicability of SWAT for predicting sediment yields in a semi-arid mountainous basin, in which the parameterization of HRU is particularly carried out to reflect the impact of rugged topography on hydrologic process in comparison of the default computation methods. With the historical gauge records, the above modification was well tested in the study area. The monthly measured runoff and sediment yields at Dage guage during the period 1985-1987 was used to calibrate the model while data from 1988 to 1990 was used for model validation. The simulation results revealed that the SWAT with the above improvement could be applied in a rugged mountainous region for erosion control and watershed management.

|13. Use of Open Source Geospatial Software within the Remote Sensing Centre, QLD.
||The Remote Sensing Centre (RSC), within the Queensland Department of Environment and Resource Management (DERM), is a leading group within remote sensing in Australia. The RSC currently uses a combination of various open source software to meet much of its geospatial processing requirements. Indeed, the systems in place at the centre have been largely developed around open source tools, which is unusual for a government agency. Principal software includes: PostGIS, QGIS, GDAL/OGR, Python and R. This poster discusses the systems in place and our experience with their implementation and use.

|14. Developing a 3D Indoor Pedestrian Simulator using a spatial DBMS.
||Most crowd simulation models for pedestrian dynamics are based on analytical approach using experimental settings without being related to real world data. In order for the models to be adapted to real world applications such as fire evacuation, some technical aspects first must be resolved. First, the base data should represent the 3D indoor model which contains semantic information of each space. Second, in order to communicate with the indoor localization sensors to capture the real time pedestrians and to store the simulation results for later uses, the data should be in a DBMS instead of files. The purpose of this paper is two folds. One is to suggest a DBMS-based 3D modeling approach for pedestrian simulations. The other is to improve the existing floor field based pedestrian model by modifying the dynamic field. We illustrated the data construction processes and simulations using the PostGIS DBMS and the enhanced pedestrian model.

|15. Developing a Campus Spatial Information System using the PostGIS.
||Most 3D models found in the literature focus on theoretical topology for exterior volumes. However, implementing a full topology for the indoor spaces is less practical due to the computational complexity and current spatial DBMSs do not support explicit 3D topological relations between geometric components. In this study, an alternative method to build a 3D indoor model with less complexity using a spatial DBMS is suggested. Focusing on the fact that semantic attributes can be stored on the floor surface, we suggest a multi-layered 3D model for indoor spaces. We show the process to build the proposed model in the PostGIS. And, then, as an example application, we illustrate the process to build and run a campus building information system.

||Parallel processing has been established as the best way to scale performance in the near future. Most of the GIS algorithms are amenable to parallel processing. We present herein some preliminary results from parallelization of common GIS modules on IBM Cell Broadband Engine, which forms the core of playstation3. We also show results of our OpenMP implementation, and some programming practices necessary for large scale applications.

|17. Automated Segmentation and Generalisation of Raster Imagery
||This study reviews past and current research activity in the area of generalisation of spatial data and presents a new methodological framework for segmentation and generalisation of raster data. In order to overcome drawbacks associated with supervised classification and generalisation of raster data, an Interactive Automated Segmentation and Raster Generalisation Framework (IASRGF) was developed and tested. Test results of the IASGRF shows that all objects derived from the generalisation of landuse data over Canberra, Australia, were well classified and mapped. The error assessment indicates that the percentile classification accuracy is 85.5%, whereas the commission error is relatively high (38.5%). More importantly, the maximum likelihood classifier using training sites and associated ground truth data suggests that the Kappa index is 0.798, which can be interpreted as a reliable and satisfactory classification result. In order to further enhance supervised classification, a post-classification was carried out. As a result, this extra process improved the overall classification accuracy.

|18. A Knowledge-Based Algorithm for Generalization of Line and Polyline Data
||Current map production systems provide reasonably complex tools and procedural cartographic protocols, however, cartographers’ interactions are essential for selecting information, symbolizing features, maintaining topological relationships, and visualizing graphical conflicts. Although an efficient generalization technique would improve the graphical quality and legibility of maps, existing techniques use an “ill-structured” approach because it is hard to devise an algorithm to solve the problem. On the other hand, expert systems use a collection of “rules of thumb” that are mainly heuristics methods or principles for decision making. It is an alternative solution to the aforementioned problem. In this research, “Generalization Expert System (GES)”: a knowledge-based solution is developed. Key steps undertaken in building GES and its components are presented here. GES is developed in Java and Python for the delivery of simplified spatial data. Its capabilities are demonstrated in a case study through simplifying roads, native vegetation and elevation data to derive 1:500,000 scale from the source maps at 1:250,000 scale over Canberra, Australian Capital Territory, Australia. Although a number of advanced applications have been developed with high technical skills, GES has a simple and user-friendly GUI that can benefit users with lesser technical skills and knowledge of spatial data management.

== Steps to create an Australian OSGeo Chapter ==
Here are my thoughts [[User:tbowden | (Tim Bowden)]] on what has to be done to get an Australian Chapter of OSGeo up and running. Feel free to edit ferociously where needed;

Following the [http://osgeo.org/content/chapters/guidelines.html Local Chapter Guidelines] we need to address the following
issues;
* '''''Chapter Roles'''''
# ''Provide member networking opportunities for support and job opportunities''
#* An active mailing list, chapter wiki and occasional face to face events should answer this need
#* Forums also provide an excellent source of community support
#* Documentation pages where you can share you experiences, tips and traps installing/running OSGeo software
# ''Software Internationalization and Localization''
#* Anything to be done here for Australia (& NZ?)
#* Some resources could be useful here, for example proj4 parameters for local projections [http://wiki.nomad-labs.dyndns.org/melbmap/published/Australian+Projections (e.g. from Melb. Mapserver User Group's Wiki]
# ''Development of prototype applications to demonstrate Open Source geospatial capabilities to local and regional audiences''
#* There are already a number of publicly available applications (wms/wfs mainly?) that are using osgeo software. Perhaps a web page pointing to them that details what software is being used in each would be a good start.
# ''Software Packaging and Customization for local and regional needs''
#* I can't see a need for Packaging or customisation for Australia. Possibly one of the biggest regional needs I can think of is pointers to free local geospatial data. Anyone got anything else?
# ''Training, Support and Development of e-Learning Contents in local languages''
#* English local enough <grin>? As far as hands on training goes, that's firmly in the hands of local contractors responding to client demand.
# ''Support Open standards and Open access to geospatial data in region''
#* Supporting Open Standards and Open acces to geospatial data is a sine qua non for OSGeo, so our chapter should publicly support this position. Previous comments about lack of formal OSGeo policy on the issue of open access to geospatial data are incorrect (thanks Arnulf).
# ''Promoting OSGeo and enhancing visibility in various forums''
#* We could look at getting an article in the local GIS print media from time to time. This should probably be driven by the contractors earning a living off GeoFOSS.
* '''''Chapter Responsibilities'''''
# ''"OSGeo Chapter" officially represents OSGeo and is formally recognized as OSGeo Project.''
# ''"OSGeo Chapter" must support the OSGeo Mission and Objectives of OSGeo.''
#* 1 & 2 require that we conduct our business with the appropriate level of equanimity and circumspection with regard to the stated goals of OSGeo. We should have a formal system of oversight of positions publicly held or stated by our chapter; Perhaps as simple as ensuring that any statements/ web content are checked by several committee members before being made "public" or official.
# ''"OSGeo Chapter" must hold regular meetings (at least annual) and provide annual report of activities to chapter membership and OSGeo Board.''
#* Australia being what it is, I'm expecting that most meetings will be virtual; probably irc with an annual face to face meeting of some sort.
# ''"OSGeo Chapter" will not entail any financial commitment from or on-behalf of OSGeo. OSGeo will also not provide any budget assistance to the "OSGeo Chapter".''
#* So if we want to spend money we have to find it ourselves. Isn't that always the way of the world? I don't think we're going to need much anyway, at least until we get enough members to look at hosting our own conf, but that's a long way off.
# ''"OSGeo Chapter" is encouraged develop and maintain "Directory Listing" of companies, people, universities and organizations involved with or using OSGeo projects.''
#* Easy to start, hard to keep up to date but worthwile anyway. At the very least a wiki page should get us started here.
# ''"OSGeo Chapter" must strive at networking with organizations to enlist participation and support for OSGeo.''
#* So what organisations should we network with? [http://www.spatialsciences.org.au/ SSI], [http://www.gita.org.au/ GITA], any others?
#* University Departments (members with close ties to their local Uni's can encourage the use of OSS in GIS/Geomatics/Surveying/Geography/Archeology courses). Melbourne guys could talk to [http://www.gs.rmit.edu.au/ RMIT] & [http://www.geom.unimelb.edu.au/ MelbUni]
#* Other collaborative OSGeo based initiatives like [http://www.seegrid.csiro.au/ Seegrid]
# ''OSGeo reserves the right to terminate its relation with an "OSGeo Chapter" if OSGeo has reasons to believe that the activities of the "OSGeo Chapter" are contrary or detrimental to the Mission and Objectives of OSGeo.''
#* Can't see that we'll have a problem here.
* '''''Chapter Benefits'''''
# ''"OSGeo Chapter" is permitted to use OSGeo Logo and other branded resources for promoting the Mission and Objectives of OSGeo.''
#* To what extent can chapter members use the OSGeo Logo and branding? As far as I'm aware, that's still an open issue of OSGeo. I'd like to see it resolved sooner rather than later.
# ''OSGeo will provide necessary infrastructure to promote communication and visibility of "OSGeo Chapter". The infrastructure will include mailing list, hosting of wiki pages, domain service for "OSGeo Chapter".''
#* Should suit us. I don't think we're going to need anything to fancy. The simpler the better. Let's not set ourselves up with anything that will lead to an onerous maintenance burden. After all, no one's paying the bills; It's all volunteer work.
* '''''Chapter Formation'''''
# ''"OSGeo Chapter" should self-organize (for instance in the OSGeo wiki, via OSGeo mailing list, etc), seeking to determine if a critical mass of interest exists to justify a chapter.''
#* Well, the self-organisation is happening, let's see how many put their hands up to do the hard yards. I'd like to think we will have a critical mass of interest and activity.
# ''"OSGeo Chapter" should prepare a mission and objectives indicating the scope of the planned chapter (geographic or linquistic extent for instance).''
#* Can't we just lift the OSGeo Mission statement and add "... for Australia" to the end?
# ''"OSGeo Chapter" should propose an official representative to liaise with the OSGeo Board. If accepted by the board, the representative will be an officer of OSGeo. ''
#* Shouldn't be a problem.
# ''"OSGeo Chapter" should submit an official expression of interest to form a chapter to the OSGeo board, listing initial members, mission, representative, legal form (incorporated?) and other supporting information. ''
#* As far as legal form is concerned, until we look at running a conf of our own, we can probably get away with some sort of non-profit club type association. Anyone have any experience/recommendations here?
# ''The OSGeo board shall then consider passing a motion forming the chapter, and designating the liason officer.''
#* If we do our bit, we shouldn't have a problem.
* '''''Other issues to consider'''''
# ''Does the mandate (geographically or linguistically) conflict with other existing chapters or chapters-in-formation?''
#* No.
# ''Does the chapter appear to have sufficient interest to justify official formation''?
#* It's starting to look that way.
# ''Does the chapter appear to be open to broad membership, and representative of the target geographic or linguistic community? (eg. if a chapter had the objective to cover all Spanish speakers, it would be inappropriate if the only interest demonstrated was from one country)''
#* Given our Geographic focus we have interest from across the country. We need to work out what form our membership takes. Is there any reason we can't just duplicate the OSGeo membership model for our chapter?
# Any other issues?

= outcome of discussions =
There was a lot of discussion at LCA2007 about the roles and functions that an Australian OSGeo chapter might provide. I will eventually try integrate them into the thoughts listed above:
* Facilitation - OSGeo Au has a role in linking people with common interests and issues. This includes people, technology and projects.
** Including broader contacts such as ASK-OSS, AGIMO, OSDM and others
* Strategy - OSGeo Au might formulate a strategy to progress the adoption of FOSS geospatial solutions (aka notes further up this page)
* Projects - Identify and progress discrete projects to promote and enhance the attractiveness of FOSS solutions
** Demonstration projects
** Reference Implementations & architectures. i.e. secure WFS proxy for corporate DMZ environments
** Contributions to existing software projects i.e. funding of further Geoserver enhancements
* Documentation - Collect and create case studies, reference implementations, business cases and other documentation required to implement FOSS solutions
** technical
** business/adminstrative
