Evaluation and Analysis of building Height with LiDAR Data

Measuring the height of a building is very crucial for various factors like understanding residential and commercial building permit, to find out how many buildings are violating the height limit set by the government, studying the structural capacity of the area, thus infer something about the population density of the area etc. This paper presents a technique to estimate building height. This is completed utilizing LiDAR data. Nowadays LiDAR remote sensing technology is getting spotlight in the field of research and development. Airborne-LiDAR sensor usually fitted in an aircraft uses laser pulses for scanning the surface of earth. The LiDAR data is processed in software, LAStools and various models are derived like Digital Terrain Model (DTM), Digital Surface Model (DSM), and Canopy Height Model (CHM) and so on. These models are used for determining shape, height and peak location of building. This can be a little contribution to smart city modelling and urban development also.
