Key checks for accurate site mapping with drone photogrammetry

Key checks for accurate site mapping with drone photogrammetry involve ensuring high ground control point density, consistent overlap in flight paths, and stable lighting conditions. These factors matter for surveyors and engineers needing reliable topographic data, as they directly affect the precision of orthomosaics and 3D models. Without attention to overlap percentages and GCP spread, distortion or elevation errors can creep in, undermining the map's value for planning and analysis.
