[Geowanking] rendered 3d scene

[Brian Russo]

There are a variety of higher-end tools that can do this.. ArcGIS 3D
Analayst, World Construction Set/other 3D Nature products, most R/S
software (e.g. ENVI). I'm assuming you don't have these tools though.

You could use 3DEM (no longer developed, but works okay last I checked
- http://www.visualizationsoftware.com/3dem).

If you have any kind of spatial analysis GIS software you could output
a DEM with the suitable berm modifications. I've done this a lot for
cut/fill type of studies (typically related to modifications to
riparian systems for construction). It's really not that hard to do
though getting a decent elevation model can be challenging. If it's a
shooting range there should be an engineering study which would have
the suitable data, though data format may be a challenge if you don't
have the right software.
