Ive made a java file that will convert the summary of a NS1 file to a text file that MapPoint 2002 can inport and map out your AP's.
It does: Latitude, Longitude, SSID, MAC, WEP
just type: java nsmp (not nsmp.class) -h
on how to use it.
It will also tell you what to do after the out.txt file is made.
Also .. delete the out.txt file before making a new one or it will just add it to the out.txt file thats already there.
Just post your questions here about it.
