In the municipality of Cantá, in Roraima State, as well as in the Amazônia, land use activities have been practiced (by loggers, cattle raisers and agriculturers) in an extensive and predatory way, causing, many times, the degradation of the environment. Using Remote Sensing and Geoprocessing techniques this work contributes to land use management of municipality of Cantá and the following tasks have been developed to: analyse the modification occurred in the vegetation canopy of the municipality and its integration to the different components of the physical environment (Geology; Geomorphology, Pedology and Climate); indicate the areas that need to be preserved, recovered, or could be used under management; delimitation of the permanent preservation areas and Indian lands. Other important result is the estimate of the municipality area for maintenance of the legal reserve based on the environmental laws: Federal law Nº 4771 from September 15, 1965 and State law Nº 5887 from May 11, 1965; Resolution Nº 303 from the Environment National Council (CONAMA); Provisory Act nº 2166-67 from August 24, 2001.
