| Abstract | O objetivo deste trabalho é apresentar uma abordagem metodológica para mapear a cobertura e o uso atual da terra, a nível regional, utilizando técnicas de Sensoriamento Remoto e Geoprocessamento. A área de estudo compreendida entre as coordenadas 01o 45' e 08o 20' de Latitude Sul e 44o 00' e 54o 00' de Longitude Oeste é coberta por 17 imagens do sensor "Thematic Mapper" (TM)do satélite Landsat. Esta metodologia consiste na geração de imagens sintéticas (vegetação, solo e sombra), através do modelo linear de mistura espectral utilizando as bandas 3, 4 e 5 do TM, para realçar os alvos de interesse e minimizar o tempo de processamento na tarefa de classificação. Esta tarefa foi realizada utilizando o processo de segmentação de imagens, seguida da classificação não supervisionada por regiões e mapeamento das classes de interesse pré-definidas (legenda temática). O resultado do mapeamento é finalmente editado pelo fotointérprete com a finalidade de corrigir os erros de classificação do sistema, baseado na sua experiência e informações auxiliares disponíveis (fotografias aéreas, mapas, etc.). A abordagem proposta é viável para grandes regiões utilizando imagens do TM ou de outros sensores de alta resolução espacial, produzindo mapa bem confiável, e permitindo a atualização a qualquer tempo e a integração com outras informações do banco de dados gerado. ABSTRACT: The objective of this work is to present a methodological approach for land use land cover regional mapping, using Remote Sensing and Geoprocessing techniques. The study area, comprised between the geographic coordinates 01o 45' and 08o 20' South Latitude and 44o 00' and 54o 00' West Longitude, is covered by 17 Thematic Mapper (TM)images of Landsat satellite. This methodology consists on the generation of synthetic images (vegetation, soil and shade), through the spectral linear mixing model using the TM bands 3, 4, and 5, to enhance the contrast among targets of interest and to minimize computer processing time during the classification task. This task was performed using the image segmentation algorithm, followed by the non-supervised classification of regions and mapping the pre-defined classes of interest (thematic legend). The mapping result is finally edited by the photointerpreter with the purpose of correcting any classification errors, based on his experience and using available ancillary information (aerial photographs, maps, etc.). The proposed approach is feasible for large areas using TM or other high-resolution data, producing very reliable map, and permitting to update it at any time and to integrate it with other information in the data base. |
