             abstract = "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 Parano{\'a}, 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.",
