value added Benefits, High Definition Surveying (HDS), Laser Scanning


The purpose of this paper is to depict and illustrate the benefits of High Definition Surveying (HDS), also known as 3-dimensional laser scanning, in contrast to field surveying methods, such as Real-time Kinematic Global Positioning System (RTK-GPS), on a hydrologic study (topographic) application. This research investigates how the improvement of application software within laser scanning, coupled with constant advancements in computer processing as well as data acquisition methods, has made the use of HDS cost effective and applicable in the surveying community. The time and cost benefit aspects of HDS applications in comparison to RTK-GPS surveying methods were analyzed, and the efficacy of both methodologies were presented for an actual production project in the conclusion.
