Abstract

Terrestrial laser scanners are becoming more familiar in the surveying industry due to the significant technological advances in equipment over the past 10 – 20 years introducing many new types of equipment and methods for the capture of point data in a variety of environments. The introduction of the terrestrial laser scanner in the surveying industry has been slowed by a lack of understanding in comparison with traditional surveying methods. This poses the question to the surveying industry of whether the relative accuracies and potential uses of terrestrial laser scanning systems can be of significant value to the surveying industry much like GPS has become over the last decade. For this project I have conducted testing on various facets of terrestrial laser scanning operation, specifically confirmation of specifications and the ability to establish a method providing legal traceability of measurements obtained from these systems. This project utilised the RIEGL LMS-Z620 terrestrial laser scanner and a Trimble S8 total station. The results from the various scan sessions were then analysed to compare the obtained data to the specified accuracies published by the manufacturer as well as extracting information that members of the surveying industry can use to evaluate the capabilities of this instrument for traditional and non-traditional scanning applications. Terrestrial laser scanning is a relatively new concept for surveyors, with scanners capable of capturing large amounts of three-dimensional coordinated data quickly and very accurately without having to physically access objects and / or environments that may be hazardous or impractical to access. In Australia surveyors have not embraced the technology as quickly as other countries due to the unknown capabilities and questions about the accuracies that can be achieved, when compared to existing equipment
