As I said in a previous post, I don't see why I need to have a GPS to get an approximation of my location. I then suggested using an open source cell list or Google API. So, I have just finished writing a program that parses your kml file from the gsmmap, send the request to Google and it will get your approx location (just like Google Maps on your mobile) and write the result in another kml file. The program is written in Java. To run it under windows: C:\Program Files\Java\jdk1.6.0_17\bin>java -jar glocation.jar Usage: glocation -i <path to input file> -o <output file> C:\Program Files\Java\jdk1.6.0_17\bin>java -jar glocation.jar -i c:\gsm.kml -o final.kml Name : MNC 03 (T-Mobile) Name : LAC 3030 Name : CELL-ID 0031 Name : CELL-ID 0032 Name : CELL-ID 135c Name : CELL-ID 24a7 Name : CELL-ID 4c2a Name : CELL-ID 4c31 Name : CELL-ID 4d10 Name : CELL-ID 51e3 Name : CELL-ID 537b Name : CELL-ID 5567 Name : CELL-ID 5f8a Name : LAC 4010 Name : CELL-ID 4c34 Name : CELL-ID 5b4b --------------------------------------- Sending data to Google... {"location":{"latitude":48.21451,"longitude":16.356414,"accuracy":511.0},"access _token":"2:BaEsaRey871FCt1e:A5vJ-lyJuPrukpMV"} lat=48.21451 long=16.356414
