<br/><br/> In Geomatics (or Land Surveying), a wide range of technologically advanced tools are used to collect geospatial data, such as total stations, satellite positioning systems (e.g. Global Positioning System (GPS)), digital imagery/photogrammetry (satellite, air-borne and terrestrial), three dimensional (3D) Laser Scanning (LS) (air-borne and terrestrial), and Geographic Information Systems (GIS). LS is a non-contact measurement method where a surface is sampled or scanned using laser technology to rapidly collect 3D point cloud data. The collected data can be used to construct digital, two dimensional (2D) drawings or 3D models useful for a wide variety of applications. The three different technologies for range measurements that are used with laser scanners are: Time of flight, phase comparison, and triangulation. Terrestrial laser scanning (TLS) or High Definition Surveying (HDS) is a practical non-contact close range 3D measurement system using laser technology. The main advantages of TLS include speed, accuracy, safety, portability and flexibility. Most TLS systems are assigned to safety class 3R (i.e. low risk). There are many different software packages for processing 3D laser scanning data, with a wide variety of deliverables (e.g. 3D model) and formats. Current trend in TLS is the development of Mobile Laser Scanning (MLS). This paper highlights the important aspects on TLS, together with various applications, TLS research works at UTM, and future potential of TLS.
