Abstract: The U.S. Army Corps of Engineers (USACE) field operating activities invest significant amounts of project time and funding on survey data collection by conventional methods. This data collection supports a variety of Civil Works projects spanning wide-ranging geographies and site conditions to include hard to access terrain. Innovations in small unmanned aerial systems (sUAS) (e.g., drones), and data processing techniques purport to produce survey grade data more efficiently and with greater coverage than conventional survey collection in hard to access terrain conditions. USACE involvement in construction of our Nation’s aging infrastructure will require extensive surveying. These efforts will support design and site assessments, cultural resources, and environmental determinations typically required by the National Environmental Policy Act, Endangered Species Act, Clean Water Act, National Historic Preservation Act, Migratory Bird Treaty Act, Clean Air Act, and the Archaeological Resources Protection Act. Efforts using sUAS provide an efficient and effective technology to support these initiatives. However, sUAS technology also offers many diverse platforms and collection sensors that provide varying types of results. An evaluation of sensor types and sUAS platforms is provided.
