// about Pix4D
Pix4D turns overlapping drone photos into survey-accurate maps, point clouds, and 3D models, with tools tuned for specific industries like agriculture, construction, and mining. Surveyors use it where centimeter-level accuracy actually matters, since it supports ground control points and RTK/PPK correction rather than just stitching pretty pictures together. It runs as desktop software or in the cloud, and most commercial drone-mapping workflows pass through it or a close competitor at some stage.
