General information about digital terrain models (DTM)
by Rüdiger Köthe

In modern geosciences digital terrain models are now used for most applications concerning the relief of the earth’s surface. Digital terrain models – introduced by MILLER & LAFLAMME (1958) – are much more qualified for the relief representation with modern computer techniques than the well knows contour lines model.

The following explanations should give a brief overview about digital terrain models:

1. What is a DTM?

2. How to create a DTM?

3. Derivations from DTM

4. For which purpose DTM are used?

5. Examples of derivations from DTM in the TRIANET project
