This paper deals with geometric quality analysis of an interest 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.
