Abstract

Geomorphological mapping with an emphasis on rock landforms was carried out in the Pohořská Mountains (Cz. Pohořská hornatina) and the positional data acquired were further processed using statistical and cartographical methods. The spatial distribution of rock landforms was investigated in relation to lithology, slope, orientation, and elevation based on an analysis using ArcGIS 9.1. The spatial distribution of rock landforms was primarily determined by the index of distribution Wij = Xi / Yj, where Xi is the percentage representation of landforms in the appropriate category and Yj is the percentage quotient of this category in the entire area studied, and wassecondarily determined according to the sum (sum distribution) of the arithmetic mean and the average deviation.
