Generación de ortofotografía y modelo digital de elevación (MDE) de alta resolución con puntos de control RTK (Real-Time Kinematic Positioning)

Abstract

The acquisition of high-resolution orthophotos and Digital Elevation Models (DEM) through the use of Real Time Kinematic (RTK) control points has emerged as an advanced and precise technology. This approach involves deploying Unmanned Aerial Vehicles (UAVs) equipped with RTK systems to achieve millimetric georeferencing of captured images. Drones, operating at low altitudes, enable the collection of detailed and high-quality data. The integration of RTK control points ensures exceptional geometric accuracy, crucial for generating three-dimensional orthophotos and DEMs. This process finds key applications in land-use planning, providing detailed information on land use, topography, and urban development. In summary, the combination of UAVs, RTK control points, and high-resolution technology constitutes an essential tool for obtaining accurate geospatial data in various contexts.
