Structure From Motion

Structure-from-motion (SfM) software is photogrammetric technique that produces 3D imagery from 2D images. SfM software and aerial imagery allow the development of low-cost, high-accuracy photographs and elevation datasets. This technique over time creates temporal change analysis at a much lower cost compared to LiDAR imagery.
