%X The article presents the results obtained with Unnamed Aerial Vehicle (UAV/UnB) high spatial resolution data to produce a density surface model (DSM). The VANT/UnB was used to obtain remote sensing visible spectral imagery with 6 cm spatial resolution and altitude data. The area of study, located in the city of Brasilia near Lake Paranoá, was imaged with 500 images of 60% common area overlapping in the 1/1000 flight scale. One density surface model (MDS) and one orthomosaic of the study area were produced with Pix4D software using a point cloud algorithm based the UAV`s GPS and attitude parameters. The orthomosaic imagery and MDS obtained from the UAV were registered with similar digital terrain model obtained by aerial photogrammetric survey from Terracap Co. called SIRGAS using 64 ground control point (GCP) by georeferencing tools in ArcGis system. In the ArcGis system, spatial analyst module algorithms (TIN generator, Raster Calculator, Slice Model, Profile Stack and mathematical operators) were used to compare the DSM/UAV with DTM/SIRGAS. Next, it was applied a statics analysis by P-Test using altitudes values measured in the area studied with topographic GPS survey and altitudes values from DSM/UAV and DTM/SIRGAS. The results obtained from the UAV`s high spatial resolution data confirmed its geometric and cartographic qualities to be used in study areas of up to 10Km2, thus making it a quality option in regards to the elevated cost of high spatial resolution obtained from satellite and aerial photogrammetric survey.
