Utilisation of Airborne LiDAR Data in Perspective of Department of Survey and Mapping Malaysia

摘要

Geospatial Mapping trend in Malaysia focus more on Light Detection and Ranging (LiDAR) for various precise application. As we knew, there are several forms of LiDAR data capturing techniques ranging from fixed terrestrial LiDAR scanning to mobile and airborne (fixed-wing, helicopter, UAVs). LiDAR data are highly accurate point cloud and commonly used to visualize topographic surface and features in three-dimensional (3D). This type of accuracy will open up a wide dimension of application towards amazing discoveries. Future generation in geospatial data revolution to cater to the abundance of rich dynamic information by manipulating any geospatial input such as LiDAR data. Department of Survey and Mapping Malaysia (JUPEM) as the authoritative government agency for any survey and mapping activities in Malaysia. The Ministry of Energy and Natural Resources has recognized JUPEM's expertise and has appointed JUPEM to lead and be a consultant to any agency in implementing activities or projects related to LiDAR. Therefore, this paper shall highlight related LiDAR technology in JUPEM inclusive standard terrain LiDAR output created such as Digital Surface Model (DSM), Digital Elevation Model (DEM), Digital Terrain Model (DTM). Last but not least, fusion and manipulate of terrain data with other geospatial data for various applications from the perspective of JUPEM.
