DTM examples

[mmyoung]

We're developing soil stabilization and storm water management methods and I'm thinking of adding the Landmark module.

Does anyone have DTM examples he or she could share? Trying to figure out if we can build models of very fiddly terrain with tight granularity, perhaps from a point cloud.

Many thanks

I've got a reasonably fiddly terrain: 3635 points. Tight? Well, it covers over 30 hectares, so not really tight.

The contours are at 1 m interval, so the max elevation is 25 m (the site is at shea sore.)

Forgot to mention: the current DTM-module cannot handle concave terrains. Either the results are plain wrong or the system crashes. I just tested with the afore-mentioned data set with reversed z-values. Crash, boom!

The old one could. Obviously, they do not have concave terrains in the McMansion-country.

I have several, mostly using 2' contours. What are you looking for exactly. Feel free to call or email me with particulars.

Can anyone tell me why VW2009 SP4 each contour polylines do not have their elevations in their properties?

Try the Site Model settings. You should be able to set those types of things there.

I am doomed since I do a lot of soundings so all these DTM are concave so I guess that VW will be crashing forever...
