In the profession of Land Surveying, new technologies, such as the Total Station (Moffit and Bouchard, 41), Light Detection and Ranging (LiDAR) devices (Campbell and Wynne, 243), and Global Positioning Systems (GPS) (Campbell and Wynne, 393), are appropriately met with some level of skepticism. When first introduced, accuracy and precision are often compared to previously used and accepted technologies and practices to determine their scientific validity. Likewise, the introduction of Unmanned Aerial Systems (UAS) has undergone serious scrutiny regarding precision, accuracy, and therefore validity in surveying by surveyors and their clients alike. This skepticism is often countered by the claims of versatility and capability of UAS by their manufacturers and proponents. Nevertheless, studies are emerging that show that UAS is a viable alternative to traditional more costly surveying methods. For example, a recent study by McKim and Creed (2016) tested UAS to conduct UAS landfill surveys, and found that the data could be collected quickly, results were accurate to about 5cm, with less accuracy in vegetated areas.
The purpose of this study is to compare using UAS for surveying against traditionally accepted methods, so see if advantages exist in cost, time, and accuracy. One advantage of UAS that is universally acknowledged is the level of safety it can bring to the hazardous profession of aerial data acquisition. From 2003 to 2013, the Occupational Safety and Health Administration (OSHA) recorded 258 fatalities in the electric utility industry alone1, many of which involved visual inspections of electrical towers that could have been accomplished utilizing UAS. In 2014, there were five fatalities from accidents in manned rotorcraft, conducting similar visual inspection work.
