watches data from a dump1090 instance for low flying planes and logs to kml files.
To buid the fork of gps-utils from my github here. The software will work without but the kml files will not have altitude data.
This needs dump1090 running in net mode:
dump1090 --net
You should now be able to visit the machine running dump1090 and see the map overlay.
node plane.js http://$address $height
$height is the height in feet for anything that you wish to log / be notified for.
