Ranging
The acronym stands for Light Detection and Ranging, or Laser Imaging, Detection, and Ranging. LIDAR is a remote sensing method for determining ranges (variable distance) by targeting an object with a pulsed laser and measuring the time for the reflected light to return to the receiver. The light pulses — combined with other data — can generate precise, 3D images of the shape of the Earth and its surface. It is commonly used to make high-resolution maps, with applications in surveying, geodesy, geomatics, archaeology, geography, geology, geomorphology, seismology, forestry, atmospheric physics, laser guidance, airborne laser swath mapping (ALSM), and laser altimetry.
