Hi All, All stressed out trying to find a source for Google Earth Terrain Data. Not just a single point all the data fro a given set of co-ordinates, say a square 100 miles by 100 mies.
 Does anyone
    a) know how to get this info from Google Earth
    b) know of a source for this data

free prefered but paid is Ok if it's reasonable.

Kind Regards
OzNielsen
