Extraction of building outline using LiDAR datasets / Muhamad Akmal Hilmi

LiDAR is a new tool that can provide very precise, accurate and high-resolution images of the surface of the earth, vegetation and environment. LiDAR uses a laser range which is mounted in a navigated aircraft to scan earth surface at very high rates and collect very dense cloud which has x y and z...
