Comparison between Airborne and mobile LiDAR in channel features
Track: 3D and Lidar Data

LiDAR has become a popular technology for high resolution topographic features and surface representation, which constitutes one of the most important input to flood hydraulic modeling. In this study, two different LiDAR platforms are used (mobile and Airborne LiDAR) to generate Digital Terrain Models for diversion channel in Madinah, west of Saudi Arabia. ArcGIS was used to process the Las flies and extract the channel geometric features (i.e. channel length, slope, width, depth, side slope).
