Technology in the Field

UAS (drones)

UAS or unmanned aircraft systems are emerging tools for professional surveyors. UAS produce aerial maps that are used for progress monitoring and as-built surveys.

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.

Total Stations

Total stations are instruments that use electronic transits to measure angles and distances to determine the location and elevations of features.
