Modern Terrain and Trench Modeling
ECI utilizes industry standard 3D structure-from-motion software to generate geospatial datasets derived by drone photos and trench photography. We utilize this technology in a variety of projects including fault investigations, paleoseimic investigations, landslide investigations, terrain change and environmental analyses.
We generate geospatial data of drone and trench photography in a multi-step procedure using AgiSoft™ 3D structure-from-motion software.
During the modeling process, photos are being corrected for scale and topography by creating an orthoimage in a first step. Unlike an uncorrected image, an orthoimage is adjusted for relief, lens distortion, and camera tilt, and can be used to measure true distances and elevation. The resulting image is geometrically corrected such that the scale is uniform.
