10 unmanned systems inside   June/July 2016 AIR HARDWARE Amazon and buy a drone and do surveys tomor- row with some cloud-based solution. The reality is you can build a model, but the models that have survey grade accuracy require a lot more knowledge and expertise in order for them to be horizontally and vertically accurate." "You don't want to use a UAV that was de- signed to be a toy or something to play with," said George Southard of GSKS Associates, a geospatial business consulting firm. "You have to use professional equipment to get a good quality product at the end. The whole idea is to have some type of unmanned aircraft that can be controlled from the ground, with the right sensors on board, to collect information about the various features on the ground." At The Beach Dr. Tiffany Briggs and James Gammack-Clark of Florida Atlantic University's Geosciences Department recently invested in an advanced UAS, the Trimble UX5, for ongoing beach restoration efforts in Boca Raton, Fla. Briggs typically uses traditional surveying methods, such as an electronic Total station and an RTK GPS receiver but for this project decided to use a UAS as well and compare the results. Gammack-Clark, who is an instructor and Ph.D. candidate at FAU, is heading the UAS as- pect of the project, which began earlier this year. During flights, the team collected high spatial res- olution and high temporal resolution aerial pho- tography, as well as generated Digital Elevation Models (DEMs) of the rapidly changing surface. "The DEMs and the Topographic Surveys will provide a mechanism for monitoring both the beach morphology change and for quantifying the volumetric changes upon it between the vari- ous surveys," Gammack-Clark said. "This dual technique of change detection will serve to sup- plement one another and provide a unique op- portunity for comparing the two methodologies." Before beginning this project, Briggs and Gammack-Clark knew they would need to cover a wide stretch of the shoreline.
