I been playing around with Google Maps Elevation API and have played around with the example Python code.
There are plenty of places visible in Google Earth/Maps where there are 3D overlays (I guess from photogrammetry). For example, Ferndown Industrial Estate ( 50°48'41.75"N, 1°54'59.85"W) has some regular industrial buildings projected in 3D. If I probe around with the Elevation API here I would expect to find building heights returned. I don't, I just get some pretty constant ground heights.
Can anyone tell me how to access the building heights through Google APIs? Is it possible?
