Abstract: | Geographic information system (GIS) can be used on the extrapolation of the specific information, allowing more rapid, lower cost and high accuracy in the land use planning at catchments. The goal of this study was to use GIS as support in the land use planning at Posses catchment (Extrema, MG, Brazil). For this, the digital elevation model (DEM) was determined using the method topogrid and the interpolation quality was evaluated of two ways: comparing contour lines from survey of the catchment (scale 1:10,000) and contour lines derived from DEM and identification of model error by root mean square error (RMSE). From the DEM class of land use planning were expanded and interpreted for the catchment according the Land Use Capability Classification System used for the Brazil. Land uses recommended for the Posses catchment were native grasslands, reforestation and environmental conservancy. Posses catchment has 11% of its lands underutilized, 12% with use above the land use capability, 58% in the appropriate use, 18% of the permanent preservation areas and 1% of the roads. |
