I am not sure if I following this but how do we know what kind of maps we need to import. We have a campus with 4 buildings on it. Wireless APs are in all buildings. Do I need obtain ground plans / floor plans in electronic format that can be added to WCS. If so, what scale is recommended and can google map assist with this?
I found that importing the maps in PNG format offers the best defintiaion in WCS. If you have your electronic plans in DWG or similar format, play around with doing a PrtScn and dropping it into Powerpoint and doing as 'Save as picture' and save it as a PNG.
Once the mpa is in this format, I import it into WCS and then open Google Earth (the proper stand alone product) and go to the tool bar at the top of the screen and use the measurement tool there.
I find the building I want on our campus, zoom in, rotate it so it matches my drawing and then use the measurement tool to measure the external walls in metres.
Seems to work fine for me
