Hello,
I'm not sure whether this is the right subforum, but I have written a small mapping utility similar to Atlas. It parses the NavAid and Fixes files of an existing Flightgear installation and displays them as an overlay on a map from the openstreetmap project. The program listens on port 5500 (the same as Atlas) for nmea packets from FighGear and displays the current plane location on the map. The airport file of FlighGear can be searched and specific information about an airport can be displayed (in a textfield).
The current version can be downloaded from
http://jmapview.sourceforge.net/
It is still in beta stage (but should work nevertheless), so please report any errors/ideas/requests for enhancements to me
Regards,
Clemens
