LIDAR (Light Detection and Ranging)
LIDAR is an active remote sensing system that allows exceptionally accurate and rapid determination of terrain and structural features (e.g. height). LIDAR produces highly accurate three-dimensional data measurements that can then be utilized by mapping, guidance, and navigation systems. For example, LIDAR data utilized by Geographic Information Systems (GIS) software, and coordinated with differential Global Positioning System (GPS) data can produce extremely accurate terrain maps that be integrated with other tactical data (e.g. location of targets, etc). LIDAR technology measures distance by calculating the time delay between the emission and ...
