World Units

Is there any easy way to get an approximate calculation of the size of the PLSM2 terrain?

I read the wiki article already about saying to run across the area and calculate the time to get world units...but my terrain is so big, it might take hours!

I have to demo this engine by Wendsday to the geology department here @ WVU and I know for a fact that thats one question they're gonna ask

Thanks in advance!

The heightmap is the resolution specifier. if your heightmap has a precision of 5m, meaning grid cell is 5m wide, and terrain widht is 1500, then terrain width size is 1500*5. Screen representation is this resolution being by multiplied"Scale" config parameter.
