LIDAR Image is the an image taken with Light Detection and Ranging (LIDAR) , which is a very newly emerged technology in the field of information technology. LIDAR Imaging is the most suitable for topographic mapping. Though LIDAR is a technology that started developing before 30 days. But the importance of LIDAR Image has gained its popularity in the field of Geographic Information System (GIS) as well as Remote Sensing and Information Technology in the last five years. The importance LIDAR Image has gained popularity because of some reasons. These are as follows-

As LIDAR Image provides very accurate information, it is used by local, federal and state governments world wide. Generally those information are used for land resource development. The images are captured using airborne LIDAR system. Those LIDAR can create very explanatory and highly precise elevation data with thousands of laser pulses sticking the surface of the earth. These data are further processed using different photogrammetric techniques to create valuable information and some important facts. Those are used for the generation of various types of maps. These topographic maps created from LIDAR Image are used to study –

In the field of slope changes LIDAR Imaging plays a very important role in determining data with precise result. The accurate data are get using LIDAR data acquisition system. The accurate elevation data is collected using “return signal strength”. The return pulses are reflected back from the target and this signal is detected by the detector of LIDAR system. LIDAR Image sometimes give faulty result. The result varies due to the following reasons.
These are –

In LIDAR Image, as the result is varying, the interpretation needs experts opinion ti generate a proper information.
Advantages of using LIDAR image :
