Remote sensing and GIS techniques applied to highway planning: casestudy ring road project (RODOANEL) surrounding Sao Paulo metropolitanregion, Brazil

摘要

This study presents a remote sensing and GIS application toanalyze the ground appropriateness to locate and construct the Rodoanelhighway, a ring road surrounding the Sao Paulo Metropolitan Region(SPMR). This study was made in close cooperation with the Sao PauloState Department of Roads (DERSA). It corresponds to section 1 ofRodoanel, whose construction will start in 1998. This Road Departmentprovided documents with several alternative locations for the Rodoanel,which is presently the most important highway construction project inBrazil. To evaluate the aptness of this area for huge civil engineeringworks, the authors made a map of land cover units using TM-Landsat(bands 1,4,7), which was associated to maps of slopes and geomorphologyin a GIS environment
