Abstract	Neste trabalho, apresenta-se e discute-se os resultados da avaliacao de dados ERS-1/SAR em conjunto com dados Landsat-5/TM, avaliando-se o grau de sinergismo entre os dados opticos e de microondas na deteccao e mapeamento de mudancas de uso e cobertura vegetal atual do solo. Foram aplicados, aos dados, a tecnica de transformacao do espaco IHS. Desta forma, foi possivel gerar mapas de uso e cobertura do solo, atraves de classificacao supervisionada, usando-se o algoritmo MaxVer, onde a acuracia do conjunto de informacoes geradas foi avaliada com base nos resultados obtidos a partir da matriz de erros, atraves da analise estatistica Kappa. Os resultados foram comparados com mapas de uso obtidos de imagens orbitais e dados de campo. A partir da analise, concluiu-se que a integracao dos dados opticos e de microondas nos possibilitou distinguir diferentes caracteristicas especificas de uso do solo atraves de imagens em composicao colorida, mostrando o sinergismo entre as informacoes multiespectrais e texturais.
