Kismet-to-KML is a project mainly written in Perl, it's free.
Converts kismet gps log files into kml files.
Kismet to KML converter.
Tried a few converters, wasn't impressed. Hopefully this will eventually use polygons to display a pseudo 3d view of network coverage and whatever other swanky advanced features Google Earth supports
HOWTO: Run the script with the prefix of your gps and xml files:
mykismetrun.[net]xml mykismetrun.gps[xml]
perl kismet2kml.pl mykismetrun
TODO: -Use power levels to weight network centre -Sort gps points by time and stamp them with their timestamp -Color networks distinctly from their neighbours -Add in KML tour to navigate the whole path -Use KML styling to distinguish networks on highlight -Probably a lot of other stuff I can't think of
