3D feature extraction refers to the process of photogrammetrically extracting features from 3D models. Planimetric feature extraction is useful for deriving terrain information along with elevation in a 3D environment. Einfomaps provides accurate digital planimetric feature extraction in various formats. Our advanced photogrammetry suite allows us to capture data from small, medium, and large scale stereo models for developing high quality cartography maps and digital topographic maps.
