  • Need outdoor mobile platform for environmental assessment, etc.
  • Particularly interested in applying Augmented Reality concepts to GIS data.
  • Provide advanced features of visualization, 3D, etc.
  • Tablet PC platform would be good, plus cameras and multiple sensors (digital compass, gps, accelerometers)
  • Frustrated with current windows options

???

  • iPod-based solution

  • Provide foundations for mobile GIS development.
  • GUI independent.

David

  • Working in an european project devoted to develop a mobile gis client for tourist, with LBS and based in open source and open standards.
  • Web apps for mobile phones and pda devices.
  • Contribute: exchange of experiences, testing.

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:

What GIS components we have ready to use?

  • 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
