Resumo


This paper presents a classification system for landform elements. The classification and mapping methods for landform elements with a DEM are based on the principle of pattern recognition and the concept of geomorphons. These elements are classified using a relative classification model based on surface shape and position. We identified 13 different landforms units in Tocantins state in the northern region of the Amazon based on the definition of the dominance and relationship of the geomorphon elements. The developed geomorphon maps are a valuable new resource for both manual and automated geomorphometric analyses. In Tocantins state, this method allowed the classification of units that correspond to geomorphologically-recognized units.
