Extraction of Micro-Terrain Features

AUG 1998

Authors: William B. Thompson; UTAH UNIV SALT LAKE CITY DEPT OF COMPUTER SCIENCE

Micro-terrain features are topographic structures relevent to the behavior of a simulation, but with a horizontal extent significantly less than the resolution of the base-level terrain data covering the area in which these structures occur. Thus, these features are not directly extractable from elevation data. While they are often apparent in aerial imagery, micro-terrain features are easily missed or confused with other features, making reliable ...
