Aerial LiDAR

LiDAR is the process of using a laser beam coupled with a rangefinder to capture the shape and position of all visible surfaces and objects. Aerial LiDAR performed using a laser mounted to an unmanned aircraft system (UAS), or drone, is best used to obtain dense 3D data over larger areas.

LiDAR is sometimes referred to as High-Definition Surveying (HDS) or laser scanning because its use of a laser offers greater data density and increased surface coverage for a higher resolution overall survey. The average laser scan yields more than one hundred million data points. These data points can be grouped into a point cloud database and manipulated using a variety of software applications to produce as-built drawings, contour maps, colorized slope maps, and other deliverables.

Using a UAS-mounted laser scanner, WithersRavenel’s remote pilots can survey large tracts of land more quickly and more completely than conventional surveyors. In addition, our aerial LiDAR equipment is excellent at penetrating vegetation, broadening the range of environments where it can be used. Aerial LiDAR brings flexibility, scalability, and accuracy to the decision-making process.
