Program to view GTopo data

[Guest]

Hi everybody,I am looking for a program that would allow me to extract the GTopo30 altitude data for a certain georeferenced point or a small region. Can anyone recommend such a freeware program?-osman

Hi Osman:if reading a few altitude data is all you want, this might be a bit of an overkill, but MicroDEM will certainly do that (and much, much more):MicroDEM 6.0 (August 2002) freeware, by Professor Peter Guth of the Oceanography Department, U.S. Naval Academy: http://www.usna.edu/Users/oceano/pguth/website/microdem.htmCheers, Holger

I discovered 3DEM a few days ago and find it excellent. Sorry I don't have the URL at hand.

Here's the link for 3DEM:http://www.visualizationsoftware.com/3dem.htmlI found it to be much easier to use than MicroDEM. MicroDEM does lots more, but I think it _is_ overkill for what most of us need to do.I used 3DEM to merge several DEM's for my scenery, in preparation for using the SDK tools to generate mesh.andy
