DEWS user interface based on uDig and GeoTools, workflows, system architecture, details of information logistics and FOSS usage will be depicted on the poster. || Matthias Lendholt, Martin Hammitzsch || GFZ German Research Centre for Geosciences<br /> |- <br /> | An open source geo-transformation library for data custodians.<br /> || 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.<br /> <br /> KMStrlib provides a unified interface to a large number of cartographic projections, and geophysical transformations (including change of vertical and horizontal datums and epochs).<br /> <br /> 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 &quot;forward-inverse&quot; 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.<br /> <br /> 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.<br /> || Thomas Knudsen, Karsten Engsager, Knud Poder, Simon Lyngby Kokkendorff<br /> || KE: DTU Space, Copenhagen, Denmark; KP: Ølstykke, Denmark (Emeritus, KMS); TK, SLK: National Survey and Cadastre (KMS), Copenhagen, Denmark; <br /> |- <br /> <br /> | Quality control of digital elevation models.<br /> || 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.<br /> <br /> 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.<br /> <br /> 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.<br /> <br /> 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.<br /> || Thomas Knudsen, Brigitte C. Rosenkranz<br /> || National Survey and Cadastre (KMS), Copenhagen, Denmark<br /> |- <br /> <br /> | INSPIRE compliant geoservices for topographic databases of the Lombardy Region in Italy.<br /> || 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.<br /> 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).<br /> Test data used for the prototype are compliant with the Standard for modelling geographic data recently approved by the Lombardy Region (february 2008).<br /> 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. <br /> || Maria Antonia Brovelli, Michele Beretta, Marco Negretti<br /> || Politecnico di Milano, Italy<br /> |- <br /> <br /> | Electronic Tag Data Visualisation<br /> || 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. <br /> || Paavo Jumppanen, Jason Hartog, Scott Cooper<br /> || CSIRO Wealth from Oceans Flagship<br /> |- <br /> <br /> | OldMapsOnline.org: Open Source &amp; Online Tools for Old Maps<br /> || Project OldMapsOnline.org is a research project targeted to the software development specialized to historical map collections. We are designing online tools for collaborative georeferencing, annotation, 3D visualization, accuracy analysis and geometadata specification.<br /> <br /> 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&amp;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.<br /> <br /> 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.<br /> <br /> Our project is in progress but we have already published several software tools and we have prototypes for the complete workflow.

<p>Wiki-Klokan: </p> <hr /> <div>{| {{Prettytable}}<br /> | The Google Summer of Code project is finished. Results and source codes are published on project web page: [http://www.klokan.cz/projects/gdal2tiles/ GDAL2Tiles: Utility for easy tile-based publishing of raster maps and KML generation]. Usage tips and manual page is available on GDAL wiki page [http://trac.osgeo.org/gdal/wiki/UserDocs/Gdal2Tiles Gdal2Tiles Utility]. Project was accepted by GDAL community as [http://trac.osgeo.org/gdal/ticket/1763 #1763]. Utility is going to be distributed with new version of GDAL 1.5.0, but it is usable also now with stable branch of GDAL and FWTools. <br /> |}<br /> <br /> <br /> For suggestions and new ideas please use [[Talk:GDAL2Tiles_SoC_2007]].<br /> <br /> [[Image:Pyramid.jpg|thumb|right|286px|Pyramid Tile Structure]]<br /> Implementation of [http://www.gdal.org/gdal_drivertut.html Raster Driver for GDAL library], which will allow to write PNG/JPG '''Pyramid Tile Structure''' as a newly supported file-format. Generated tiles will contain also XML metadata, so after putting them on any webserver they could be used as data source for:<br /> <br /> *[http://earth.google.com/ Google Earth] (with [http://earth.google.com/kml/kml_21tutorial.html#superoverlays SuperOverlay KML])<br /> *[http://maps.google.com/ Google Maps]<br /> *[http://www.openlayers.org/ OpenLayers]<br /> *[http://www.worldkit.org/ WorldKit]<br /> <br /> and probably other viewers.<br /> <br /> Tile structure will follow recommendation from [http://wiki.osgeo.org/index.php/Tile_Map_Service_Specification OSGEO Tile Map Service Specification]. <br /> Simple utility 'gdal2tiles' for converting [http://www.gdal.org/formats_list.html supported file-formats] into new tile structure will be created.<br /> <br /> Implemetation of the file format driver will allow to export map raster data into Google Earth, Google Maps and other online viewers from any of applications which use GDAL library. <br /> <br /> Idea for this project was suggested by FrankW at [[GDAL SoC Ideas]].<br /> <br /> == Implementation details ==<br /> <br /> === Pyramid Tile Structure and Metadata ===<br /> <br /> * Metadata from [http://wiki.osgeo.org/index.php/Tile_Map_Service_Specification TMS Specification] will be created as a main source of georeference (especially [http://wiki.osgeo.org/index.php/Tile_Map_Service_Specification#TileMap_Resource TileMap Resource XML]). <br /> * KML supports only EPSG:4326 (latlong with WGS84 datum) projection, so reprojection is needed if source projection is different. How to turn off unneeded tiles by Regions in KML?<br /> * It would be nice to support zoom levels of Google Maps tiles (this have to be checked, maybe from [http://mapnik.org/ Mapnik] project, example of [http://mapnik.org/tiling/oxford/ generated tiles]. More info is available here: http://michal.guerquin.com/googlemaps.html and http://docs.codehaus.org/display/GEOSDOC/Google+Maps<br /> <br /> === GDAL Driver ===<br /> <br /> * implements Create() function, so random access to format is possible (so for example direct warping of image into tiles will run).<br /> <br /> === GDAL2Tiles utility ===<br /> <br /> * Command-line utility similar to existing [http://www.gdal.org/gdal_utilities.html GDAL utilities].<br /> * Should be able to process files without proper georeference (to publish X-Ray images, vedute and other large bitmap files too).<br /> <br /> == Possible future extension (not necessarily part of SoC project) ==<br /> <br /> * Support for [http://dev.live.com/virtualearth/sdk/ Microsoft Virtual Earth] - they have generator [http://research.microsoft.com/mapcruncher/ MapCruncher]<br /> * Support for [http://worldwind.arc.nasa.gov/ NASA World Wind]. Tile generation for [http://www.worldwindcentral.com World Wind] is done via GDAL using the dstile utility available [http://www.worldwindcentral.com/wiki/Dstile_howto here].

Generated tiles will contain also XML metadata, so after putting them on any webserver they could be used as data source for:<br /> <br /> *[http://earth.google.com/ Google Earth] (with [http://earth.google.com/kml/kml_21tutorial.html#superoverlays SuperOverlay KML])<br /> *[http://maps.google.com/ Google Maps]<br /> *[http://www.openlayers.org/ OpenLayers]<br /> *[http://www.worldkit.org/ WorldKit]<br /> *[http://www.worldwindcentral.com World Wind]<br /> <br /> and probably other viewers.<br /> <br /> Tile structure will follow recommendation from [http://wiki.osgeo.org/index.php/Tile_Map_Service_Specification OSGEO Tile Map Service Specification]. <br /> Simple utility 'gdal2tiles' for converting [http://www.gdal.org/formats_list.html supported file-formats] into new tile structure will be created.<br /> <br /> Implemetation of the file format driver will allow to export map raster data into Google Earth, Google Maps and other online viewers from any of applications which use GDAL library. <br /> <br /> Idea for this project was suggested by FrankW at [[GDAL SoC Ideas]].<br /> <br /> == Implementation details ==<br /> <br /> === Tile Structure ===<br /> <br /> * Metadata from [http://wiki.osgeo.org/index.php/Tile_Map_Service_Specification TMS Specification] will be created as a main source of georeference (especially [http://wiki.osgeo.org/index.php/Tile_Map_Service_Specification#TileMap_Resource TileMap Resource XML]). <br /> * KML supports only EPSG:4326 (latlong with WGS84 datum) projection, so reprojection is needed if source projection is different. How to turn off unneeded tiles by Regions in KML?<br /> * It would be nice to support zoom levels of Google Maps tiles (this have to be checked, maybe from [http://mapnik.org/ Mapnik] project, example of [http://mapnik.org/tiling/oxford/ generated tiles]. More info is available here: http://michal.guerquin.com/googlemaps.html and http://docs.codehaus.org/display/GEOSDOC/Google+Maps<br /> * WorldWind tile generation is done via GDAL using the dstile utility available [http://www.worldwindcentral.com/wiki/Dstile_howto here]<br /> <br /> === GDAL Driver ===<br /> <br /> * implements Create() function, so random access to format is possible (so for example direct warping of image into tiles will run).<br /> <br /> === gdal2tiles ===<br /> <br /> * Command-line utility similar to existing [http://www.gdal.org/gdal_utilities.html GDAL utilities].<br /> * Should be able to process files without proper georeference (to publish X-Ray images, vedute and other large bitmap files too).<br /> <br /> == Possible future extension (not necessarily part of SoC project) ==<br /> <br /> * Support for more viewers ([http://dev.live.com/virtualearth/sdk/ Microsoft Virtual Earth] with generator [http://research.microsoft.com/mapcruncher/ MapCruncher], [http://worldwind.arc.nasa.gov/ NASA World Wind] with generator [http://www.worldwindcentral.com/wiki/Dstile_howto DSTile], any other?) <br /> * Simple GUI for 'gdal2tiles' under Windows/Linux/Mac done with Python (one of WxWidgets/TKinter/EasyDialogs).<br /> * Implementation of GDAL Reader for generated tile structure (could be based on [https://svn.osgeo.org/svn/gdal/trunk/gdal/frmts/wcs/ gdal/frmts/wcs], thanks FrankW)<br /> * [http://www.staremapy.cz/zoomify-analyza/ Zoomify Tile Structure] as alternative or modification of Zoomify with support for generated structure<br /> * Maybe implementation of georeference for tilestructure by use of GML.<br /> <br /> == Schedule ==<br /> <br /> * May 28: Designing the file format, XML Metadata formats(KML, TMS XML files, MS Virtual Earth, ...?) which will be supported have to be chosen and tested with their respective viewer applications, sample map is published.<br /> * July 9: Alfa version of GDAL Driver for Tile Structure Writer is uploaded into official SVN.<br /> * August 20: Final version of the driver as well as gdal2tiles utility are uploaded and reviewed.<br /> <br /> == Competitors ==<br /> <br /> Commercial applications like: [http://www.arc2earth.com/ Arc2Earth] have similar functionality. Several (mostly commercial) generators for Google Earth tiles were mentioned on http://www.ogleearth.com/.<br /> <br /> Microsoft Research project [http://research.microsoft.com/mapcruncher/ MapCruncher] also generates tiles, but with metadata only for their MS Virtual Earth.<br /> <br /> [http://www.zoomify.com/ Zoomify] could be now used as tiling program for SuperOverlay in GoogleEarth with free [http://www.zoomify.com/express.htm ZoomifyerEZ] and generator [http://www.staremapy.cz/zoomifykml/ ZoomifyKML] (which I created as a part of my Master Thesis).<br /> <br /> == What new functionality this project brings ==<br /> <br /> Clean open-source implementation of tile structure export. Any application which uses GDAL library will easily be able to export files into a tile structure. Supplied utility gdal2tiles will convert [http://www.gdal.org/formats_list.html any supported file format] with georeference into tiles, it will also allow batch mode processing of files.<br /> <br /> GDAL is strong library for processing maps and large raster files, including reprojection, so any already georeferenced maps could be easily converted for simple on-line publishing on a webserver without special server requirements (like MapServer is). Advantages of this approach are described in [http://wiki.osgeo.org/index.php/Tile_Map_Service_Specification TMS Specification].<br /> <br /> Reader could be implemented later, which will (with support on the side of UNM MapServer) allow to access published tile structure using WMS standard, where UNM MapServer will act as a proxy.<br /> <br /> == Who will use results of this project ==<br /> <br /> Several organizations and individuals who handle processing of maps.<br /> <br /> Institutions which will use the 'gdal2tiles' utility from this project, as I am cooperating with them:<br /> * Moravian Library in Brno, Czech Republic<br /> * Historical institute of Czech Academy of Sciences<br /> * Czech National Library<br /> * National Library of Scotland<br /> * University of Connecticut Library (with their grant [http://www.rlg.org/en/page.php?Page_ID=20522#article1 &quot;Building a Globally Distributed Historical Sheet Map Set of Austro-Hungarian Topographic Maps, 1877-1914&quot;], cooperating with New York Public Library, University of Connecticut Library, and Library of the American Geographical Society. It is a grant about building a scalable workflow and toolset for map libraries to add cartographic content to the Web.)<br /> <br /> == Student's Biography ==<br /> <br /> My name is Klokan Petr Přidal, I have finished Master degree in Applied Informatics at [http://www.muni.cz/ Masaryk University in Brno], now I am in the first semester of postgraduate study of Cartography at [http://www.cvut.cz/ Czech Technical University in Prague].

I have experience with Linux/Solaris system administration. I like Python language, but I have also used other languages (C language, PHP).<br /> I have supplied some patches into Gnumeric ([http://bugzilla.gnome.org/show_bug.cgi?id=330129 #330129], [http://bugzilla.gnome.org/show_bug.cgi?id=334257 #334257]).<br /> I founded a http://mplayerosx.sf.net/ project and I also won a competition in programming application for Mac using http://dictosx.sf.net/ (Objective-C).<br /> My primary desktop is Gnome and Linux, but I also use Mac, Windows and Solaris.

Any application which uses GDAL library could easily export files into tile structure. Supplied utility gdal2tiles will be convert any supported file format with georeference into tiles, it will allow batch mode processing of files.<br /> <br /> GDAL is strong library for processing maps and large raster files, including reprojection, so any already georeferenced maps could be easily converted for simple <br /> on-line publishing and a webserver without special server requirements (like mapserver is). Advantages of this attitude are written in TMS Specification.<br /> <br /> Reader could be implemented later, which will (with support on the side of UNM MapServer) allow to access published tile structure by WMS standard, if UNM MapServer will act as proxy.<br /> <br /> === Who will use result of this project ===<br /> <br /> Several organizations and individuals who handle processing of maps.<br /> <br /> Institutions who will use the 'gdal2tiles' utility from this project, as I am cooperating with them:<br /> * Moravian Library Brno<br /> * Historical institute of Czech Academy of Sciences<br /> * Czech National Library<br /> * National Library of Scotland<br /> * University of Connecticut Library (with their grant [http://www.rlg.org/en/page.php?Page_ID=20522#article1 &quot;Building a Globally Distributed Historical Sheet Map Set of Austro-Hungarian Topographic Maps, 1877-1914&quot;], cooperating with New York Public Library, University of Connecticut Library, and Library of the American Geographical Society.

<p>Wiki-Klokan: </p> <hr /> <div>== GDAL Raster Driver for PNG/JPG Tile Structure + gdal2tiles utility ==<br /> <br /> === Overview ===<br /> <br /> Implementation of [http://www.gdal.org/gdal_drivertut.html Raster Driver for GDAL library], which will allow to write PNG/JPG tile structure as a new supported file-format. Generated tiles will contain also XML metadata, so after putting them on any webserver they could be used as data source for [http://earth.google.com/ Google Earth] (with [http://earth.google.com/kml/kml_21tutorial.html#superoverlays SuperOverlay KML]), [http://maps.google.com/ Google Maps], [http://www.openlayers.org/ OpenLayers], [http://www.worldkit.org/ WorldKit] and probably other viewers.<br /> <br /> Tile structure will follow recommendation from [http://wiki.osgeo.org/index.php/Tile_Map_Service_Specification OSGEO Tile Map Service Specification]. <br /> Simple utility 'gdal2tiles' for converting supported file-formats into new tile structure will be created.<br /> <br /> Implemetation of the file format driver will allow to export map raster data into Google Earth, Google Maps and other online viewers from any of applications which use GDAL library. <br /> <br /> Ideas for this project was suggested by FrankW at [[GDAL_SoC_Ideas]].<br /> <br /> === Schedule ===<br /> <br /> * May 28: Designing of file format, all XML Metadata (KML, TMS XML files, MS Virtual Earth, ...?) have to be known and tested with supported viewers, sample map is published.<br /> * July 9: Alfa version of GDAL Driver for Tile Structure Writer is uploaded into official SVN.<br /> * August 20: Final version of the driver as well as gdal2tiles utility are uploaded and reviewed.<br /> <br /> === Implementation details ===<br /> <br /> ==== Tile Structure ====<br /> <br /> * Metadata from [http://wiki.osgeo.org/index.php/Tile_Map_Service_Specification TMS Specification] will be created as main source of georeference (especially ). <br /> * KML supports only EPSG:4326 (latlong with WGS84 datum) projection, so reprojection is needed if source projection is else.<br /> * It would be nice to support zoom levels of Google Maps tiles (this have to be checked, maybe from [http://mapnik.org/ Mapnik] project, example of [http://mapnik.org/tiling/oxford/ generated tiles].<br /> <br /> ==== GDAL Driver ====<br /> <br /> * implements Create() function, so random access to format is possible (so for example direct warping of image into tiles will run).<br /> <br /> ==== gdal2tiles ====<br /> <br /> * Implemetation with simple GUI for Windows/Linux/Mac done with Python (one of WxWidgets/TKinter/EasyDialogs).<br /> * Should be able to process files without proper georeference (to publish X-Ray images, vedute and other large bitmap files too).<br /> <br /> === Possible future extension (not necessary part of SoC project) ===<br /> <br /> * Support for more viewers (Microsoft Virtual Earth - they have generator MapCruncher, NASA World Wind, any other?) <br /> * Implementation of GDAL Reader for generated tile structure (could be based on gdal/frmts/wcs, thanks FrankW)<br /> * Zoomify Tile Structure as alternative or modification of Zoomify with support for generated structure<br /> * Maybe implementation of georeference for tilestructure by use of GML<br /> <br /> === Competitors ===<br /> <br /> Commercial applications like: [http://www.arc2earth.com/ Arc2Earth] have similar functionality. ''Several (mostly commercial) generators for Google Earth tiles should be mentioned here too.''<br /> <br /> Microsoft research project [MapCruncher] also generates tiles, but with metadata only for their MS Virtual Earth.<br /> <br /> [http://www.zoomify.com/ Zoomify] could be now used as tiling program for SuperOverlay in GoogleEarth with free [http://www.zoomify.com/express.htm ZoomifyerEZ] and generator [http://www.staremapy.cz/zoomifykml/ ZoomifyKML] (which I made as part of my Master Thesis). <br /> <br /> === What new functionality this project brings ===<br /> <br /> Clear open-source implementation of tile structure export. Any application which uses GDAL library could easily export files into tile structure. Supplied utility gdal2tiles will be convert any supported file format with georeference into tiles, it will allow batch mode processing of files.<br /> <br /> GDAL is strong library for processing maps and large raster files, including reprojection, so any already georeferenced maps could be easily converted for simple <br /> on-line publishing and a webserver without special server requirements (like mapserver is). Advantages of this attitude are written in TMS Specification.<br /> <br /> Reader could be implemented later, which will (with support on the side of UNM MapServer) allow to access published tile structure by WMS standard, if UNM MapServer will act as proxy.<br /> <br /> === Who will use result of this project ===<br /> <br /> Several instututions/ who handle processing of maps.<br /> <br /> Institutions who will use this project, as I am cooperatin with them:<br /> * Moravian Library Brno<br /> * Historical institute of Czech Academy of Sciences<br /> * Czech National Library<br /> * National Library of Scotland<br /> * University of Connecticut Library (with their grant [http://www.rlg.org/en/page.php?Page_ID=20522#article1 &quot;Building a Globally Distributed Historical Sheet Map Set of Austro-Hungarian Topographic Maps, 1877-1914&quot;], cooperating with New York Public Library,<br /> University of Connecticut Library, and Library of the American Geographical Society. It is a grant about building a scalable workflow and toolset for map libraries<br /> to add cartographic content to the Web)<br /> <br /> === Student's Biography ===<br /> <br /> My name is Klokan Petr Přidal, I have finished Master degree in Applied Informatics at Masaryk University of Brno, now I am in the first semester of postgraduate study of Cartography at [http://www.cvut.cz/ Czech Technical University in Prague].
