Abstract

Today’s society demand faster, easier, safer and more accurate spatial information than ever before. Over the past 15 years surveyors have seen the introduction of reflectorless technology and more recently, laser scanning. Reflectorless technology and laser scanning has become a useful tool in many surveying applications. This technology has opened the door to the majority of demands that the community and other surveyors request. Due to this evolving technology specific laser scanning instruments have been developed. These instruments can cost in excess of half a million dollars and require specific software. In recent times companies have introduced laser scanning capabilities into total stations to reduce costs and integrate technology, which has launched the new evolution in total stations with most now having reflectorless and scanning capabilities included within the instrument. This project was undertaken to address surveyor’s uncertainties regarding reflectorless technology and laser scanning capabilities within total stations. A number of tests were conducted by both the Leica 1205R and the Trimble S6 instruments to compare both accuracy and performance. The three tests performed varied from simple point comparisons to scanning of volumes and the measuring of building encroachments. The results found there to be very small errors when performing simple point comparisons over a small range. The total stations also performed very well in the volume scans as both instruments produced similar results. Lastly, some problems were found with the encroachment testing as software capabilities limited my outputs. Both reflectorless and the laser scanning capabilities performed very well allowing me to test and analyse their full potential
