Extraction of Micro-Terrain Features

Abstract : 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 detection, based on imagery alone, problematic. This report describes an automated method for extracting high fidelity models of small-scale ravine features by augmenting a hydrological analysis with computer vision techniques.
