# Currently a Proof of Concept:  
# Script parses kismet *.xml log files for GPS data and creates a map of access points.
# output is URL for google maps API, requires maps API Key - http://code.google.com/apis/maps/signup.html
#
# N.B. Google maps appears to have limit to the length of URLs it can handle, 
#  for this reason the script is limited to plotting only the first 50 encounted access points
#
# Limit should be sufficient for site-surveys, not so good for outputting war drive findings
#
# Unsecured APs are green, WEP secured are yellow, and WPA are red
