The 43 pages that link to LiDAR, each with the reason it gives.

• Remote sensingBroader topic: Airborne and spaceborne laser returns map terrain and vegetation structure.

• RadarCompared with: Unlike radar, it uses optical wavelengths and can provide finer spatial detail in clear conditions.

• LaserRelated: Short laser pulses or modulated beams reveal range and shape from return signals.

• Rayleigh scatteringRelated: Molecular backscatter can contribute to lidar signals in clear air.

• Inverse-square lawRelated: Its return signal strength depends partly on distance-related spreading and target geometry.
