【 摘 要 】

Light Detection and Ranging (LiDAR) is one of the most recent and useful active remote sensing tools; it provides accurate horizontal and vertical information by direct time measurement of a short laser pulse's reflection on the Earth surface. The ability of LiDAR data to accurately characterize terrain has led many users in Malaysia, to employ this technology for various applications, including engineering and infrastructure, environment, disaster and natural resource management. However, there are some technical challenges faced by technology operators and users, particularly in Malaysia, in terms of data acquisition, processing and quality control. In this paper, some of the technical challenges, i.e. mismatches between LiDAR and ground land survey data, differences between coordinates derived from the primary GPS network 2000 and the CORS station, MyGeoid and NGVD height differences, changes in topographical features, LiDAR Data management and the lack of a standard for data acquisition and quality control in Malaysia, will be discussed.
