I've just posted my work of the extracts ouf the RSM Database. To display the location of all the Cell Sites of all the mobile providers as per what is registered in the RSM Database as KML files that can be used with Google Earth, or Google Maps online.
This doesn't necesarily mean that the telco actually has a transmitter there, it just means they are allowed to transmit from there.
It's based on the new LAT/LONG Geocodes in the RSM Database, so the pin-points should be more accurate than they were before.
Check it out in my blog.
