3D Surface Modeling, Change Detection, & Geologic Analysis

Landslide Technology's experts in geomorphology have developed techniques for comparisons of various surface data sources, including aerial and terrestrial LiDAR and state-of-the-art photogrammetric methods.  A sample video is provided below.  These comparative techniques are excellent for detecting rockfall activity, landslide movement, remote discontinuity measurements, rock slope scaling effectiveness, and spillway safety.
