<div>== Code Sprint - what's that? ==<br />
<br />
[[Image:Code-sprint-foss4g2010.jpg|thumb|400px|FOSS4G 2010 code sprint, in Barcelona]]<br />
A code sprint is about getting a group together to work on Open Source software, sitting around a table and sharing ideas. It's not just about writing code, as you know a project has many needs including documentation, testing, and providing feedback. What a better way to give feedback and give back to the project that you love than to spend a day with the project's developers. There are roles needed to be filled, no matter what your expertise.<br />
<br />
With such a short timeframe (one day) you should probably use this page to set a specific goal for your project. But don't worry, if all you get done is actually sitting at the same table with the project's developers and talking about the next release, that is also great :)<br />

<br />
== What to Bring ==<br />
<br />
* power bars (only outlets for 30 computers exist)<br />
<br />
== How to get there from the Sheraton ==<br />
<br />
The easiest way to get there from the Sheraton is to catch the free shuttle bus along 16th Street to Larimer, then it's about a half mile walk from there (7-10 minutes) - just take a left on Larimer and keep going straight into the campus. More detail to come shortly on how to get to the exact rooms etc.<br />

<div>== Overview ==<br />
This is not a formal OSGeo project, just a spot for a few OSGeo folks to share some ideas.<br />
The idea is to elaborate foundations of design and implementation of [http://www.opensource.org Open Source] GIS application(s) for mobile devices. The homepage for this project can be found at [http://mobile.maptools.org/ Mobile GIS]. If you have any comments about the homepage, please visit the [http://mobile.maptools.org/index.phtml?page=mailinglist.html Mobile GIS Support] page, and post/subscribe to the mailing list.<br />
<br />
<br />
Our main objectives are to discuss:<br />
* principles of mobile software design<br />
* high usable User Interface on mobile devices<br />
* key functions automation<br />
* usage of latest communication techniques<br />
* portability<br />
<br />
== Hardware ==<br />
<br />
Mobile GIS will be made to work on a variety of hardware platforms. It should be usable on desktop systems, laptops, tablet PCs, and other various pocket computers. Support for cell phones with Java capability is also an option.<br />
<br />
''TODO: List pros/cons for devices on which Mobile GIS can be run.''<br />
<br />
== Operating Systems / Platforms ==<br />
<br />
This section is devoted to discuss features as well as pros and cons (+/-) of various mobile operating systems and software platforms.<br />
<br />
Here are listed platforms we have discussed, in alphabetical order:<br />
<br />
=== Linux ===<br />
<br />
From [http://www.openembedded.org/project-overview OpenEmbedded Overview]:<br />
<br />
''OpenEmbedded is a full-featured development environment allowing users to target a wide variety of devices.(...)OpenEmbedded is a tool which allows developers to create a fully usable Linux base for various embedded systems. It has been designed to be able to handle different hardware architectures, support multiple releases for those architectures, and utilize tools for speeding up the process of recreating the base after changes have been made. Currently it can run on any Linux distribution, and plans are in place to allow it to work under Windows.''<br />
<br />
'''Note:''' Familiar's Linux distribution is entirely based on OpenEmbedded system.<br />

=== Key Features ===<br />
<br />
''TODO: List of key features''<br />
<br />
==== Brainstorm ====<br />
<br />
'''Note:''' ''Please, feel free to extend the list of features here.''<br />
<br />
'''Question:''' ''What do you think about rank features listed in this brainstorm section? It could be achived by putting asterix (*) next to features you think are important. Any other ideas?''<br />
<br />
This section is devoted to a summary of our discussion on the OSGeo mailing list.<br />
List of ideas of Open Source Mobile GIS features:<br />
<br />
* User Interface<br />
** configurable UI: turn on/off UI elements, switch to [http://en.wikipedia.org/wiki/Kiosk_software kiosk mode]<br />
** create a wizard type tool for the desktop (for example in [http://www.qgis.org QGIS]) to create data collection forms, etc. to be transported to the handheld device (similar to as [http://www.esri.com/software/arcgis/arcpad-appbldr/about/forms.html ArcPad Forms])<br />
** binding UI action to hardware elements, for example zooming with hardware keys or scrolls<br />
** use of voice capabilities<br />
*** ask for operation confirmations (Yes, No, Cancel) and accept answering by speech recognition or by pushing hardware keys<br />
** use of LEDs, for example to indicate states of various operations: GPS location accuracy/low PDOP, edited layer has not been saved, no network connection, synchronization is in progress, catching tracklog/feature vertices with GPS, etc.<br />
** Internationalization<br />
** Client UI should have an option for a 'simplified' UI, so that those with less computer experience can still use the software effectively. Advanced option can be used by those with more experience/who need the most functionality from the client.<br />
<br />
* GIS functionality<br />
** map tools: zoom-in, zoom-out, pan<br />
** integration of map and attributes database<br />
** data query tool<br />
** features editing<br />
*** automated and configurable functions like: snapping, polygon closing, layers autosave<br />
** measures<br />
** projections, for example [http://mateusz.loskot.net/projects/proj4/ PROJ.4 for Windows CE]<br />
<br />
* data sources and providers, see [[#Spatial Data Formats]]<br />
** remote<br />
*** accessed via [http://en.wikipedia.org/wiki/Web_Feature_Service Web Feature Service]<br />
** local<br />
*** file based<br />
*** local RDBMS, for example [[#SQLite]]<br />
<br />
* data synchronization<br />
** network-based:<br />
*** on-demand - temporal network connection required<br />
*** continuous - permanent network connection required<br />
** file-based:<br />
*** with files copied from flash memory card<br />
*** with files transfered by [http://en.wikipedia.org/wiki/Infrared_Data_Association IrDA], [http://en.wikipedia.org/wiki/Bluetooth Bluetooth] or cable<br />
<br />
* GPS functionality<br />
** navigation<br />
** routing from current position<br />
** querying data based on current position<br />
** catch location from GPS, for example to create point on a layer<br />
** signal/protocol logging<br />
** automated map large-scale switching while measuring/catching features with GPS, for example from 1:500 or 1:1000 <br />
<br />
* Other<br />
** ''some kind of'' integration with external devices, for example laser range finder, camera<br />
<br />
=== Spatial Data Formats ===<br />
<br />
This section discusses data formats considered for local spatial datastore on a mobile device.<br />
Proposed formats are listed in alphabetical order.<br />
<br />
==== Spatial Data File (SDF) ====<br />
<br />
From [http://usa.autodesk.com/adsk/servlet/index?siteID=123112&id=5169479#section4 Autodesk's FAQ] about the SDF format:<br />
<br />
''Autodesk’s new spatial data file (SDF) is a powerful single file that provides many of the capabilities of a relational database (RDBMS). Each SDF file can contain multiple geometry types (lines, polygons, and points) as well as feature attributes. A spatial data file enables you to organize and manage your data as GIS features, providing a solid foundation for a smooth transition to an RDBMS in the future if the need arises.''<br />
<br />
Some additional info on the SDF format available at [https://fdo.osgeo.org/nonav/docs/SDF/index.html https://fdo.osgeo.org/nonav/docs/SDF/index.html]<br />
<br />
''TODO: We need more details about SDF format! If you know anything about this format, please share your knowledge here. Thanks!''<br />
<br />
''TODO: Is there any specification available to download?''<br />
<br />
==== ESRI Shapefile ====<br />
<br />
ESRI Shapefile is a file-based format, simple and easy to use in mobile application, though it does not support complex data relations natively.<br />
Important features of ESRI Shapefile format:<br />
* availability of portable libraries: [http://shapelib.maptools.org Shapelib] and [http://ogr.maptools.org/drv_shapefile.html OGR], both work on Windows CE and Linux<br />
* easy to use and create on mobile devices<br />
* very popular format in GIS world<br />
* well-documented format<br />
<br />
See:<br />
* http://en.wikipedia.org/wiki/Shapefile<br />
* [http://www.esri.com/library/whitepapers/pdfs/shapefile.pdf ESRI Shapefile Technical Description]<br />
<br />
==== SQLite ====<br />
<br />
From the [http://www.sqlite.org SQLite] website:<br />
<br />
''SQLite is a small C library that implements a self-contained, embeddable, zero-configuration SQL database engine.''<br />
<br />
SQLite engine seems to be a good candidate for a local geospatial database managed on a mobile device. SQLite features which are mostly interesting for Open Source GIS system for mobile devices include:<br />
<br />
* easy to use and create on mobile devices<br />
* highly portable library, works well on Linux PDAs and Windows CE devices (see [http://sourceforge.net/projects/sqlite-wince sqlite-wince])<br />
* Open Source Software<br />
* single-file format<br />
* it's been used in GIS, see [http://www.gdal.org/ogr/drv_sqlite.html SQLite driver for OGR] and [http://grass.itc.it/grass61/manuals/html61_user/sqlite.html SQLite driver for GRASS]<br />

=== Spatial Data Formats ===<br />
<br />
This section discusses data formats considered for local spatial datastore on a mobile device.<br />
Proposed formats are listed in alphabetical order.<br />
<br />
==== Spatial Data File (SDF) ====<br />
<br />
From [http://usa.autodesk.com/adsk/servlet/index?siteID=123112&id=5169479#section4 Autodesk's FAQ] about the SDF format:<br />
<br />
''Autodesk’s new spatial data file (SDF) is a powerful single file that provides many of the capabilities of a relational database (RDBMS). Each SDF file can contain multiple geometry types (lines, polygons, and points) as well as feature attributes. A spatial data file enables you to organize and manage your data as GIS features, providing a solid foundation for a smooth transition to an RDBMS in the future if the need arises.''<br />

''TODO: Is there any specification available to download?''<br />
<br />
==== ESRI Shapefile ====<br />
<br />
ESRI Shapefile is a file-based format, simple and easy to use in mobile application, though it does not support complex data relations natively.<br />
Important features of ESRI Shapefile format:<br />
* availability of portable libraries: [http://shapelib.maptools.org Shapelib] and [http://ogr.maptools.org/drv_shapefile.html OGR], both work on Windows CE and Linux<br />

''OpenEmbedded is a full-featured development environment allowing users to target a wide variety of devices.(...)OpenEmbedded is a tool which allows developers to create a fully usable Linux base for various embedded systems. It has been designed to be able to handle different hardware architectures, support multiple releases for those architectures, and utilize tools for speeding up the process of recreating the base after changes have been made. Currently it can run on any Linux distribution, and plans are in place to allow it to work under Windows.''<br />
<br />
'''Note:''' Familiar's Linux distribution is entirely based on OpenEmbedded system.<br />

''TODO: List of key features''<br />
<br />
==== Brainstorm ====<br />
<br />
'''Note:''' ''Please, feel free to extend the list of features here.''<br />
<br />
'''Question:''' ''What do you think about rank features listed in this brainstorm section? It could be achived by putting asterix (*) next to features you think are important. Any other ideas?''<br />
<br />
This section is devoted to a summary of our discussion on the OSGeo mailing list.<br />
List of ideas of Open Source Mobile GIS features:<br />
<br />
* User Interface<br />
** configurable UI: turn on/off UI elements, switch to [http://en.wikipedia.org/wiki/Kiosk_software kiosk mode]<br />
** create a wizard type tool for the desktop (for example in [http://www.qgis.org QGIS]) to create data collection forms, etc. to be transported to the handheld device (similar to as [http://www.esri.com/software/arcgis/arcpad-appbldr/about/forms.html ArcPad Forms])<br />
** binding UI action to hardware elements, for example zooming with hardware keys or scrolls<br />
** use of voice capabilities<br />
*** ask for operation confirmations (Yes, No, Cancel) and accept answering by speech recognition or by pushing hardware keys<br />
** use of LEDs, for example to indicate states of various operations: GPS location accuracy/low PDOP, edited layer has not been saved, no network connection, synchronization is in progress, catching tracklog/feature vertices with GPS, etc.<br />
** Internationalization<br />
** Client UI should have an option for a 'simplified' UI, so that those with less computer experience can still use the software effectively. Advanced option can be used by those with more experience/who need the most functionality from the client.<br />
<br />
* GIS functionality<br />
** map tools: zoom-in, zoom-out, pan<br />
** integration of map and attributes database<br />
** data query tool<br />
** features editing<br />
*** automated and configurable functions like: snapping, polygon closing, layers autosave<br />
** measures<br />
** projections, for example [http://mateusz.loskot.net/projects/proj4/ PROJ.4 for Windows CE]<br />
<br />
* data sources and providers, see [[#Spatial Data Formats]]<br />
** remote<br />
*** accessed via [http://en.wikipedia.org/wiki/Web_Feature_Service Web Feature Service]<br />
** local<br />
*** file based<br />
*** local RDBMS, for example [[#SQLite]]<br />
<br />
* data synchronization<br />
** network-based:<br />
*** on-demand - temporal network connection required<br />
*** continuous - permanent network connection required<br />
** file-based:<br />
*** with files copied from flash memory card<br />
*** with files transfered by [http://en.wikipedia.org/wiki/Infrared_Data_Association IrDA], [http://en.wikipedia.org/wiki/Bluetooth Bluetooth] or cable<br />
<br />
* GPS functionality<br />
** navigation<br />
** routing from current position<br />
** querying data based on current position<br />
** catch location from GPS, for example to create point on a layer<br />
** signal/protocol logging<br />
** automated map large-scale switching while measuring/catching features with GPS, for example from 1:500 or 1:1000 <br />
<br />
* Other<br />
** ''some kind of'' integration with external devices, for example laser range finder, camera<br />
<br />
=== Spatial Data Formats ===<br />
<br />
This section discusses data formats considered for local spatial datastore on a mobile device.<br />
Proposed formats are listed in alphabetical order.<br />
<br />
==== Spatial Data File (SDF) ====<br />
<br />
From [http://usa.autodesk.com/adsk/servlet/index?siteID=123112&id=5169479#section4 Autodesk's FAQ] about the SDF format:<br />
<br />
''Autodesk’s new spatial data file (SDF) is a powerful single file that provides many of the capabilities of a relational database (RDBMS). Each SDF file can contain multiple geometry types (lines, polygons, and points) as well as feature attributes. A spatial data file enables you to organize and manage your data as GIS features, providing a solid foundation for a smooth transition to an RDBMS in the future if the need arises.''<br />
<br />
Some additional info on the SDF format available at [https://fdo.osgeo.org/nonav/docs/SDF/index.html https://fdo.osgeo.org/nonav/docs/SDF/index.html]<br />
<br />
''TODO: We need more details about SDF format! If you know anything about this format, please share your knowledge here. Thanks!''<br />
<br />
''TODO: Is there any specification available to download?''<br />
<br />
==== ESRI Shapefile ====<br />
<br />
ESRI Shapefile is a file-based format, simple and easy to use in mobile application, though it does not support complex data relations natively.<br />
Important features of ESRI Shapefile format:<br />
* availability of portable libraries: [http://shapelib.maptools.org Shapelib] and [http://ogr.maptools.org/drv_shapefile.html OGR], both work on Windows CE and Linux<br />
* easy to use and create on mobile devices<br />
* very popular format in GIS world<br />
* well-documented format<br />
<br />
See:<br />
* http://en.wikipedia.org/wiki/Shapefile<br />
* [http://www.esri.com/library/whitepapers/pdfs/shapefile.pdf ESRI Shapefile Technical Description]<br />
<br />
==== SQLite ====<br />
<br />
From the [http://www.sqlite.org SQLite] website:<br />
<br />
''SQLite is a small C library that implements a self-contained, embeddable, zero-configuration SQL database engine.''<br />
<br />
SQLite engine seems to be a good candidate for a local geospatial database managed on a mobile device. SQLite features which are mostly interesting for Open Source GIS system for mobile devices include:<br />
<br />
* easy to use and create on mobile devices<br />
* highly portable library, works well on Linux PDAs and Windows CE devices (see [http://sourceforge.net/projects/sqlite-wince sqlite-wince])<br />
* Open Source Software<br />
* single-file format<br />
* it's been used in GIS, see [http://www.gdal.org/ogr/drv_sqlite.html SQLite driver for OGR] and [http://grass.itc.it/grass61/manuals/html61_user/sqlite.html SQLite driver for GRASS]<br />
