Terrain analysis for armed forces

Abstract

The main activities of armed forces take place in the terrain. Knowledge of terrain impact on such activities is very substantial for their achievement. Terrain impact on chosen activities can be described using mathematical models and these can be applied in GIS. Beside the quality of mathematical models, the quality of used data, mainly their vagueness, has fundamental influence on final results of terrain analysis. When calculating parameters for complex models, it is necessary to consider data quality which influences the level of vagueness of the resulting calculations. To express this level of vagueness, a method of fuzzy logic was chosen and then fuzzy functions were used when calculating chosen tasks—model of terrain passability and model of helicopter landing sites selection. The complete procedures were applied in the environment of ArcGIS 10.
