This document discusses the benefits of using unmanned aerial systems (UAS) for infrastructure inspections and environmental monitoring. UAS provide improved timeliness and quality of data collection at a lower cost compared to traditional methods. They allow access to difficult or dangerous locations and provide high-definition photos, near-immediate data downloads, and the ability to stream information anywhere. The document outlines various applications of UAS for infrastructure inspections, environmental facilities and ports, pipeline security and construction monitoring, environmental inspections, and 3D modeling. It notes advantages of UAS include new opportunities, scalability, flexibility, multi-disciplinary capabilities, and cost savings.
