How can google make all the mountains 3d?Normally, sattelite images are just flat. So Google calculated 3D-heights into the images which makes the mountains look 3D.


Are the mountains exactly the same or just a little?In hi-res areas, the should look as in reality, as far as I can tell.


Whn is google going to increase its resoulution for different countries??? :-?You have to ask Google on this one, we don't know. But I think they are already working on that.

I moved this thread to 'Using Google Earth'. A redirect should have remained at 'Great things you've found' where this thread does not belong.

matrix,
How did you check the height?
My calculated estimates proved relatively close.

Hi
3D data is public for more than 1 year from NASA.
I believe US is 30x30m precision, rest of the world is 90x90 and 900x900 meters.
Search for SRTM keyword.
