                         accuracy of the data generated byradar sensors, which offer the 
                         Digital Elevation Model (MDE) and its local derivations, comparing 
                         by means ofthe Kappa index its accuracy to the topographic truth 
                         Of the catchment area of the Capivara watershed. Adetailed 
                         analysis was performed to detect, improve, validate and correct 
                         some errors related to the altimetricdimensions belonging to the 
                         respective level curves, where the TIN interpolation tool 
                         (irregular mesh oftriangulation) was applied, thus generating the 
                         Digital Elevation Model (MDE) in matrix format representing 
                         theEarth Truth. The TOPODATA database altimetry MDE was imported 
                         into the QGIS 2.2.0 software, isolating theareas of real interest, 
                         resulting in a new representative matrix file for crossing the 
                         matrix of confusion andvalidation through the Kappa Index. Some 
                         places with flat relief, such as the case of classes 1 and 
                         2,TOPODATA presented some overestimations of the topographic 
                         classes and, in relation to areas with ruggedrelief and marked 
                         slope, the data analyzed showed an underestimation of the 
                         topographic classes. Based on theresults obtained, the evaluation 
                         of the accuracy of TOPODATA processed to the Topographical Truth 
                         of theCapivara watershed presents a MDT of good classification 
                         with more than 50%, which enables such a productas an economically 
                         feasible and fast alternative for mapping and environmental
