Extraction and Analysis of Different Terrain Derivatives from Point Cloud Airborne LiDAR Measurements of Reduced Data Volumes

Author(s):

Fahmy FF Asal

Topographic parameters such as slope, aspect, profile curvature, contour curvature and drainage network are usually known as terrain derivatives that enjoy a wide range of engineering and environmental applications. Different Surveying Engineering techniques such as ground surveying, GPS, digital photogrammetry in addition to remote sensing technologies constitute main sources for digital elevation data exploited in extraction of different terrain derivatives at varying qualities. Airborne LiDAR is an efficient technology that can capture very dense and accurate digital elevation data, known as point cloud LiDAR data for extended areas in relatively short times with reasonable costs. However, processing of very high-density point cloud LiDAR data could lead ... view more»
