Abstract :
In the surroundings of large Brazilian cities, such as Sao Luis, State capital of Maranhao, there has been a very fast and chaotic growth of population, frequently at the cost of landscape degradation. This study presents the results of a joint analysis of optical and microwave sensor data, for the classification of land use features, as well as the change of landscape, at the northern section of this island. Data integration allowed the discrimination among different land use/land cover types, showing the synergism between multispectral and textural information
