Utilizing Terrestrial Laser Scanning Dataset for Cadastral Surveying

In the Fourth Industrial Revolution (4.0 IR) era, the adoption of Terrestrial Laser Scanning (TLS) has seen a remarkable upsurge in its application within land development contexts. TLS, a surveying method harnessing laser technology to gauge distances between objects and generate intricate three-dimensional representations of the immediate environment, has become increasingly pivotal in ensuring the precise delineation of property boundaries and establishing dependable land records. This research delves into a crucial aspect of this technological shift, investigating the potential disparities in area measurement accuracy when comparing conventional cadastral techniques Total Station (TS) to TLS, specifically in the Malaysian context. For data collection and processing, the BLK 360 laser scanner and the ES 105 TS were chosen for their capacity to capture high-resolution point cloud data and provide precise angle and distance measurements. The study’s findings unveil TLS as a promising alternative for cadastral surveys in Malaysia, effectively maintaining boundary vector displacement well within the acceptable threshold of 0.050 meters at specified locations. On average, the discrepancies in northing and easting coordinates are impressively low at 0.004 meters and 0.002 meters, respectively. This research highlights the potential of TLS to enhance the accuracy and efficiency of cadastral area calculation in Malaysia, contributing to the establishment of more reliable land records and improved land development practices within the 4.0 IR framework.
