LiDAR Services are the various functions that can be performed by means of the LiDAR technique. LiDAR is one of the premier technologies that is used widely in Optical remote Sensing. LiDAR is Light Detection And Ranging. LiDAR (Light Detection And Ranging) is the Remote Sensing technology that can determine the range and other information about a particular distant object. This is done by means of measuring the properties of scattered lights.
The LiDAR Services are the products of LiDAR survey. The quality of LiDAR Services depend upon the quality or accuracy of data collected during the LiDAR Survey.
A LiDAR (Light Detection And Ranging) sensor emits 500 to 50,000 laser pulses per second in a scanning array. The sensor scan side to side as the aircraft flies over the concerned survey area. This is done by the help of a pulsed laser beam. As this scanning goes on, simultaneously 20,000 to 1,00,000 points are registered or measured per second. The informations about the points or objects are calculated fro the time interval of the LiDAR (Light Detection And Ranging) pulses. The time delay of these transmitted pulses and detected reflected signals are taken as a distance of an object or surface. The spacing of these points depend upon the flying height and scan angle.
The LiDAR (Light Detection And Ranging) System comprises of another three important technologies which work simultaneously with the LiDAR sensor. They are :
