Stereo Compilation: - Stereo compilation refers to the mapping of vector features from oriented stereo pair (pair of overlapping photographs) in 3 dimensions.
A digital terrain model (DTM) also consists of mass points (X, Y) with elevation values (Z) but unlike the DEM, the mass points are not in the form of a regularly spaced grid.
Earth On Mapping has the entire photogrammetric workflow and expertise in house. We employ a bundle of SW packages, together with our own priority algorithms to enable fast, accurate .
Light Detection and Ranging (LiDAR) can determine how far objects are away from each other by shining a laser onto a target and analyzing the light that bounces back.
