Comment on A Word About DTMs and TINS by Dave

I appreciate your clarifications and you will get no argument from me. 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.

I’d clarify your definitions a little more.
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.

First time blogger, good information. 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.

I miss Randall and his family a lot. 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.

You’ve got a point, I never knew what it cost to run the sites but I do know there was several people donating, I realize though that it wasn’t enough to justify the level of time they spent.

I think Randall and Ralph got tired of people taking advantage of the “free” help that was being provided.

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

Great explanation. Even an EE can understand that.
