• Interested in development of mobile GIS framework, a set of libraries and components usable in other projects, end-user solutions.
• Provide foundations for mobile GIS development.
• GUI independent.

Project output

We can see three different applications for mobile devices: a) End-user application, a kind of viewer or editor b) Data collecting solution, with GPS, editing and automation features c) The third one, is a kind of LSB solution for mobile phones or other small devices with GPS/GSM capabilities.

a) and b) are main lines of development proposal. c) is very different application to a) and b)

Development platform

a) Langauge: - C/C++ - it seems to be our language of choice - Java - mainly used on mobile phones - Python - who has worked with Python on mobile devices?

b) Operating platform - Windows Mobile >= 5.0 - the main OS on the mobile devices market at the moment; target platform of the first prototype - Linux - most of us would prefer to develop for Linux, but it's not very popular yet, no commercial support for Linux-based mobile devices, etc.

b) Tools: - Visual Studio 2005 - a commercial toolset, the only option for Windows Mobile development :-( - gcc-based toolset for cross-compilation, but there is no debugger

Type of application

- standalone application (most of participants likes this one) - thin client (a web-based solution) - strong client (standalone application or a combination)

Data

Data sources localization we want to support:

• local
• remote

Main data types we want to support:

• vector
• raster

Various data sources and formats possible to use:

• vectors:
  • local files (ie. shapefiles, mapinfo)
  • GML and WFS
  • database (ie. SQLite)
• rasters:
  • tile server for rasters
  • WMS

Available libraries to access and operate spatial data:

• GDAL/OGR for Windows CE
• Shapelib

What GIS components we have ready to use?

• Windows Mobile
  • OGR
  • PROJ.4 and PROJ.4 port for Windows CE
  • SQLite

• Linux
  • most of currently available portable libraries are runnable on Linux on mobiles

GPS

All Mobile GIS BOF participants agree that we need a GPS support.

Windows Mobile

• GPS API and GPS Intermediate Driver (GPSID) - see short overview
• gpsd does not officially run on Windows-based systems, what about porting it?
• There is always an option to develop our own portable library for reading and parsing NMEA sentences

from serial/... port in a separate thread (no TCP/IP server/listener required)

Linux

• gpsd works very well on Linux
