Definition of lidar. : a device that is similar in operation to radar but emits pulsed laser light instead of microwaves.
Point cloud of the Grand Coulee Dam symbolized by LAS class code. Source lidar made available by the National Oceanic and Atmospheric Administration (NOAA) Coastal Services Center.

This is accomplished, to a large degree, by the automated collection of measurements that are sampled very densely.
