MAPPING OF RURAL PROPERTIES WITH REMOTELY PILOTED AIRCRAFT TO COMPLY WITH THE RURAL ENVIRONMENTAL REGISTRATION
Resumo
This study evaluates the feasibility of using Remotely Piloted Aircraft (RPA) in mapping rural properties to comply with the Rural Environmental Registry (CAR), emphasizing the positional quality of cartographic products and the methodological standardization of environmental mapping. The survey was conducted on a 21.95-hectare rural property using aerial photogrammetry with RPA, implementation of Control and Verification Points by GNSS/RTK, and photogrammetric processing using open-source software. The cartographic products generated were an orthomosaic, a Digital Elevation Model (DEM), land use and land cover maps, slope maps, and CAR environmental unit maps. Positional accuracy was evaluated based on the Positional Accuracy Standard for Digital Cartographic Products (PAP-PCD), using seven independent verification points. The results showed a Root Mean Square Error (RMSE) of 0.203 m in planimetry and 0.160 m in altimetry, placing the products in Class A for the 1:2000 and 1:1000 scales, respectively. The results demonstrate that the integration between UAV, GNSS/RTK, and normative evaluation constitutes a robust and applicable approach to CAR (Rural Environmental Registry), contributing to greater precision, reliability, and standardization of rural environmental mapping.
