Description
Summary: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 features. Keywords: DEM, Geomorphology, Modelling, Este trabalho apresenta um sistema de classificacao de elementos do relevo. O metodo de classificacao e mapeamento para elementos do relevo utiliza MDE e se baseia no principio de reconhecimento de padroes e conceitos de geomorphons. Estes elementos sao classificados utilizando um modelo de classificacao relativa, baseada na forma da superficie e posicao dos elementos. Foram identificados 13 diferentes unidades de relevo no estado de Tocantins, localizado na regiao norte, na Amazonia legal, com base na definicao do dominio e da relacao entre os elementos de geomorphons. Os mapas de geomorphons desenvolvidos sao um novo e valioso recurso tanto para analise geomorfometrica manual e automatizada. No estado de Tocantins, este metodo permitiu a classificacao das unidades que correspondem as feicoes geomorfologicas reconhecidas. Palavras Chaves: MDE, Geomorfologia, Modelagem
