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

Linux

 * gpsd works very well on Linux
