[Geowanking] rendered 3d scene

David,
I've actually got a license for Surfer (I've used it to create
contours, etc), but without an adequate DEM I'm not sure I'd be able to
render a 3d scene.
I've looked at Leveler (and other programs like it) in previous years
for other projects and hadn't considered it for this one; building a
model of the area (with vegetation, mountains, etc) may be a lot of work.
Maybe the "solution" is to take a photo and draw a berm on it with a
paint program. Yuck!
Best Regards,
Brent Fraser
