This work was developed by use geotechnologies and supported to the diagnosis and environmental management of Cambará do Sul County, Rio Grande do Sul State, Brazil. The forest survey generated map of land use by MAXVER classification on images TM LANDSAT 5. The field survey diagnosed use conflicts based in the Environmental Law.
