UTILIZAÇÃO DE RPAS (DRONES) COMO FERRAMENTA NA ENGENHARIA CIVIL: AEROFOTOGRAMETRIA

In recent years, the use of Remotely Piloted Aircraft (RPAs) for digital aerial photogrammetry has expanded significantly, particularly in the field of engineering. This technology has enabled the efficient, cost-effective, and faster collection of high quality data and essential information across various fields and projects. Among the primary applications of aerial images captured by RPAs in engineering is the acquisition of planialtimetric data, a technique widely used in topography to obtain detailed information on specific areas of the Earth's surface. This study aims to provide an overview of the history of using these devices, present the rules and regulations for their operation, and evaluate the feasibility of using RPAs for planialtimetric surveys and cartographic production of terrain surfaces. A case study is presented, including aerial photographs processed with specific software to create products such as a Digital Surface Model (DSM), Digital Terrain Model (DTM), orthophotos, and contour lines. Results demonstrated that RPAs, when combined with photogrammetry, are viable for planialtimetric topographic surveys, presenting minimal errors and ensuring greater reliability in the generated products.
