Light Detection and Ranging
LiDAR, similar to radar, is a highly sophisticated sensor that transmits a multiple laser pulse rate to the surface of the ground from the belly of an aircraft. The pulse rate when processed, provides elevation information at the ground surface.

The first commercial LiDAR unit in the U.S. was made available around 1993. Today, there are many in use around the world.

For several years, ACA has provided LiDAR primarily for evaluating stormwater basins, land development and flood insurance maps. When LiDAR alone may not be the total solution, ACA combines photogrammetry to improve the overall accuracy. Sometimes referred to as "LiDARgrammetry" it has become the preferred method for developing 3D breaklines.

ACA provides LiDAR for small to large land areas. Our quality control and quality assurance is dedicated to achieving final results that meet or in some cases have exceeded FEMA specifications.

If you need LiDAR, give ACA a try!
