Assessment of positional quality in spatial data generated by VANT using point and linear feature for cadastre applications

Currently the validation of the quality of cartographic information has been an issue ever more evident and important. With the emergence of the National Spatial Data Infrastructure (INDE) in Brazil, there were several technical specifications in order to regulate and standardize the many processes related to national cartographic production. In this context, the objective of this study is to evaluate the positional planimetric accuracy of orthophoto generated from an embedded sensor on a UAV platform by applying methods of point and linear features, according to the Brazilian standard for positional accuracy (Decree Law 89 817 combined with ET-ADGV), considering as a reference survey performed using RTK GNSS positioning technology. The results obtained demonstrate that both linear feature method (Double Buffer method) and the pontual feature method showed similar results, obtaining classification Class B to scale 1: 1,000, according to the Decree Law No. 89,817 / ET-ADGV
