Orthomosaics, point clouds, and 3D models transform aerial and ground imagery into precise maps for surveying, construction, and environmental monitoring. An orthomosaic is a geometrically corrected composite image where every pixel aligns to real-world coordinates, enabling accurate measurement. Point clouds are dense collections of 3D coordinates from laser scanning or photogrammetry, capturing surface details like terrain or structures.
