UAVs (Unmanned aerial vehicle) have been widely used in the generation of orthomosaics and digital elevation models (DEM) that give support geospatial analyzes. Sometimes these analyzes require rapid surveys and/or are make in remote areas, which makes it unfeasible to use UAVs associated with the points of support for the correction of position, adjustment and evaluation of the quality of orthomosaic and MDEs. Currently it is possible to automate the generation of these products using pre-established routines available in specialized programs to manipulation UAV´s images. This work evaluates the planimetric quality of the orthomosaics produced from images collected with UAVs associated with the use of automated routines of specialist software, without the use of support points. As a result, it was observed that 100% of the orthomosaics obtained was classified into Class A of the scale 1: 50,000  or higher (PEC-PCD - Cartographic Accuracy Standard of Digital Cartographic Products) and, the best planimetric accuracy was 1:5000. The orthomosaics showed regular pattern of error distribution, not presenting preferred areas of deformation (edge / center). The errors in the measured distances in orthomosaics are less than 1.6% of the measured distance.
