These days i am thinking about to put all the Navigation stuff i have implemented in JAVA as an opensource package.
This includes: a database compiler (written in JAVA) for GDF input files,
a route calculator, visualization module in Java2d, awt, swt and opengl, a Maneuver generation module, a guidance module, voice output module, position control module including a map matching module .... and a lot of other useful services.
All this stuff is running currently under linux, win32 and WindowsCe (Dell Axim x51).
To get a full opensource solution we needed to implement a database compiler for e.g. Openmap data.
What do you mean?
