ACKNOWLEDGEMENT
First and foremost I would like to thank The Almighty and my parents for have blessed me to overcome all the obstacles I came across while proceeding with this dissertation. I am deeply indebted to my guide and coordinator, Ms. Sreedevi Viswanath, Lecturer, Department of Civil Engineering, Sree Buddha College of Engineering, for her sincere guidance, timely help and much appreciated correction during every step of this work. I am thankful to Mr. E.K.Bhass, Head, Dept. of Civil Engineering, Sree Buddha College of Engineering for the guidance and timely advice in preparing this seminar. I would like to thank Dr. Somi Sebastian, Principal, Sree Buddha College of Engineering, Pattoor, for granting me the permission to do my seminar work. I thank our management and all the faculties of Civil Engineering Dept for the support in my endeavor. I express my heartful thanks to all my friends for their precious help. VISAKH.G.NAMPOOTHIRI

ABSTRACT
LiDAR is a remote sensing technology that measures distance by illuminating a target with a laser and analyzing the reflected light. The term LIDAR stands for Light Detection and Ranging. This is a remote sensing method used to examine the surface of the Earth. LiDAR is popularly known as a technology used to make high resolution maps such as flood risk mapping, coastal zone mapping, real estate development, For surveys like oil and gas exploration surveys, engineering or construction surveys, urban modelling, forestry and contour mapping. LiDAR mapping provides an introduction to a maturing technology used to acquire land based Digital elevation Models (DEM), and an existing mature technology used to acquire marine (undersea) DEMs. Common to both the land-based and marine based systems by the use of lasers, integrated into what are known as Light Detection And Ranging systems, or LiDAR. LiDAR uses ultraviolet, visible, or near infrared light to image objects and can be used with a wide range of targets, including non-metallic objects, rocks, rain, chemical compounds, aerosols, clouds and even single molecules. A narrow laser beam can be used to map physical features with very high resolution. Where valid, comparisons of LiDAR to other mapping technologies are presented to provide an understanding of current traditional practices. In many cases the combination of LiDAR with other technology creates a result that is unachievable with a single methodology. Finally, conclusions are presented for discussion purposes that draw on the experiences of LiDAR.
