Download and extract the latest version of kisgearth.
To convert kismet logs to a google earth .kml-file use the kisgearth.pl perl script:
./kisgearth.pl -G /var/log/kismet/Kismet-Jul-05-2009-1.gps -oN mymap.kml -n 1 -s -- /var/log/kismet/Kismet-Jul-05-2009-1.xmlFor more options use
./kisgearth.pl -hNow start Google Earth and open the mymap.kml file and you are done.
The drawback of this method is the need of having google earth installed. On the other hand you can browse your collected data with many details about the networks available, while other solutions such as the "gpsmap" command only creates static images with the found networks on them.
