google elevation data?

[MKH-VB]

I have heard that there is some elevation data from google maps that is downloadable.  I am in need of a large area of contours. I know I can get it from the National Map Viewer, but wondering if this comment about google is true?  Anybody know anything?  thanks

MKH,

You'll need to install Google Earth Pro. I haven't used it, but here's where to go :

With Civil 3D you can use freely available GIS Contour data :

You can also download the SRTM 1 arc second (30m resolution) digital elevations from the Earth Explorer at the USGS website. http://earthexplorer.usgs.gov/

I doubt Google Earth would have any data with greater resolution.

I saw the chosen solution and I was really desperate! Do they really suggest that procedure?

I can't believe you really have to "paint" on Google Earth!

Rather than wasting time on that stuff, I think it's way better to specify exactly for which points or the intervals to get elevations for an area...

B,

Pretty cool!

Thanks Dave,

Actually that's a "productivity" tool for my work, so I'm glad if it helps...

I just saw to the other video in Plex.Earth tutorials, the one for draping imagery to terrain!

Maybe less usefull, but cool (hmm... clients may like it though) 🙂
