Resumo: | The aim of this research is to develop an object-based methodology for semi-automatic mapping of relief units. The study area is the municipality of São José dos Campos, located in São Paulo State, Brazil. For this end, a multilevel hierarchical semantic network (meant for the storage and reproduction of expert knowledge) together with fuzzy logic and a set of multispectral, geomorphometric and textural variables were used. The geomorphometric and textural variables were extracted from a DEM, obtained from a stereo pair of ASTER/Terra images. The DEM altimetric accuracy was evaluated. The validation of the final relief units map was accomplished by means of object-based statistical indices derived from an error matrix, obtained by means of a comparison between the classified scene and a reference map. This reference map was produced from a visual interpretation of the stereoscopic images. Based on the obtained results, the object-based approach has shown to be a suitable method for relief units mapping. |

O objetivo desta pesquisa foi desenvolver uma metodologia semi-automatizada de mapeamento de unidades de relevo, que utiliza análise orientada a objeto (AOO). A área de estudo é o município de São José dos Campos (SP). Com esse intuito, utilizou-se uma rede semântica hierárquica multinível para representação do conhecimento do especialista/geomorfólogo, além de lógica nebulosa e um conjunto de variáveis multiespectrais, geomorfométricas e texturais. As variáveis geomorfométricas e texturais foram derivadas de MDE obtido de imagens estereoscópicas do sensor ASTER/Terra. A acurácia altimétrica desse MDE foi avaliada. A validação do mapa de unidades de relevo foi realizada, considerando os objetos (ou segmentos) por meio de estatísticas derivadas de uma matriz de erros, obtida da comparação com um mapa de referência gerado a partir da interpretação visual das imagens estereoscópicas. Com base nos resultados obtidos, concluiu-se que AOO é uma metodologia viável para a semi-automação de procedimentos relacionados ao mapeamento de unidades de relevo.
