Abstract

Impervious surface areas (ISA) are indicative of urbanization and through their mapping, it is possible to measure the urbanization impact generated on the urban ecosystem. Remote sensing is a valuable tool that enables both the mapping of land use and land cover types and estimating the percentage of impervious coverage. This study, therefore, aims at contributing to the mapping of ISA in the São José dos Campos - SP urban area, using multispectral images taken by the Thematic Mapper sensor onboard the Landsat-5 satellite. Three methods for estimating impervious surface areas were employed in this study: Normalized Difference Built-up Index (NDBI), Normalized Difference Vegetation Index (NDVI) and Built-up index (BU). The obtained results were validated using an orthorectified Quickbird image with 0.5 meter of spatial resolution.
