A historic golf course in Denver, CO. became the hotspot for a demonstration of next gen integrated UAS mapping technology. Denver Public Works and Denver Parks & Recreation are facilitating a complete redesign and revitalization of the 200-acre City Park Golf Course to integrate storm and groundwater drainage systems as part of a larger f lood mitigation program in the city. The project's contract documents outline some site- specific development requirements to support the storm- water management such as the integration of storm and groundwater drainage systems to temporarily hold and slow f loodwater during major storms. Environmental specifications for reforestation require the contractor to carefully monitor earthwork and site development activities. Working with the general contractor, Frontier Precision, a survey and civil engineering company headquartered in Bismarck, North Dakota with offices in Colorado, used the opportunity to compare the latest in fully integrated UAS-based LiDAR and direct georeferencing with con- ventional survey mapping techniques. Flexibility & Speed To map the 200-acre golf course, Frontier Precision got a first-hand look at Microdrones' new mdLiDAR1000. Designed for ease-of-use, the mdLiDAR1000 is a fully- integrated unmanned aerial system equipped with a LiDAR sensor, software and workf low capable of produc- ing high accuracy geospatial solutions very quickly. Nathan Stephenson, laser scanning engineer in charge of technical scanning services with Frontier Precision, was particularly excited about seeing the mdLiDAR1000 solution for the first time. He added, "We haven't sup- ported aerial LiDAR platforms to-date because the technology was still being developed and wasn't yet at a cost-effective rate. But, from a technology perspective, we are moving more to the use of LiDAR with direct geo- referencing because of the technology's f lexibility, ease of data collection and improved safety because of limited need for ground base stations." Stephenson worked with Yannick Savey, Microdrones LiDAR test pilot, to develop the f light plan. The LiDAR data was collected in four f lights, each about 20 minutes in length at 3.5 m/s at an altitude of 40 m.
