                         area mapping that followed all the steps of a photogrammetric 
                         aerial survey. We performed flight planning, GNSS survey of ground 
                         control points and ground check points, digital aerial imaging 
                         using a small format digital camera onboard a small unmanned 
                         aerial system, GNSS post processing and photogrammetric 
                         processing. Pix4D photogrammetry software was used to process 
                         images and coordinates in order to generate a digital orthophoto 
                         mosaic and a Digital Surface Model DSM, both with and without 
                         Ground Control Points GCP. Our main objective was to evaluate 
                         these generated products regarding positional accuracy compliance 
                         to Brazilian Cartographic Accuracy Standard for Digital Products 
                         PEC-PCD using a mathematical model of statistical analysis and 
                         error vector plot. We also analyzed the information presented on 
                         quality report from Pix4D regarding consistency. All planned data 
                         were collected and the results were fully achieved. The mapped 
                         area using GCP reached a quality level class A at 1:1000 scale in 
                         orthomosaic and class A at 1:500 scale in DSM. Orthomosaic without 
                         GCP reached class A only at 1:10000 scale and DSM without GCP was 
                         not possible to classify in any class or scale due to large 
                         vertical errors.",
