About LIDAR

LIDAR (LIght Distance And Ranging, also known as Airborne Laser Swath Mapping or ALSM) is a relatively new technology that employs an airborne scanning laser rangefinder to produce accurate topographic surveys of unparalleled detail.
Compare high-resolution LIDAR topography with conventional 1:24,000-scale contour topography.
