Terrestrial Light Detection and Ranging (T-LiDAR) Technology

T-LiDAR technology utilizes reflected laser pulses sent from a tripod-mounted scanning instrument to determine distances to targets of interest. The resulting dataset is a 3 dimensional model or "point cloud" of millions of XYZ data points, spaced only a few millimeters apart. This highly detailed dataset is used by USGS scientists to create topographic models, make detailed measurements, and...
