Technology in the Field
LiDAR (airborne and ground-based)
Light detection and ranging (LiDAR) is a remote sensing method used to examine the surface and features of the Earth. It uses lasers to measure variable distances and helps surveyors create maps more accurately, precisely, and flexibly.
Global navigation satellite system (GNSS) receivers use signals from satellites to collect position, velocity, and time information to accurately map and model the physical world. GPS is an example of a GNSS.
