I included it to my favorites website listing and ought to be coming again quickly. Remember to take a look at my website too and inform me what you think.

The brief articles hosted here were meant to give someone unfimilar with machine control a “knocking around knowledge” and being so I took some liberties with certain explinations.

My understanding is that a DTM is typically made up of data that represents a terrain surface. It might be gridded data (eg least squares, min curvature, etc or simply closely spaced observed data - eg LIDAR or laser ranging). A DTM can also be a TIN but a it's not necessary. A TIN is a triangulated surface but has special characteristics. It has "break lines" which are typically breaks in slope which triangles DO NOT CROSS. Examples are ridge lines, streams, curbs, geological fault lines, escarpments etc. Typical programs to generate DTM are gridding programs or triangulation programs (eg TRIANGLE or ACORD by Schewchuk or Watson resp) and are a Delaunay triangulation. TINs are typically NOT Delaunay. I’d clarify your definitions a little more.

Just wondering if you have ever used Terramodel and if so how does it compare to Carlson. Ive been using Terramodel for a little over two years now ( mostly on road project) and found it easy to learn and use. First time blogger, good information.

VB Design was a family, we all learned so much but none of us learned what we should have. We all thought we were so busy.... I just wish Randall could see my family now. See how far we have come, what we are doing now. I have news for R.R. it would be nice to have late night chats with him and Jess again. Maybe a game of Diablo. I miss Randall and his family a lot.

Also Chuck and Se7en was there also. They were quite enertaining. The reason this user conference was not as good as the SWEUG is that I was at that one, and not at this one.
