Applying Small UAS to Produce Survey Grade Geospatial Products for DOT Preconstruction & Construction Activities

Recent advances in small unmanned aerial systems (UASs) and sensing technologies have enabled relatively low cost and effective surveying methods for preconstruction, construction, and slope sites. However, the commercial software that accompanies these technologies produces inconsistent and unreliable survey results and there are no guidelines for ensuring the quality of the data. Without proper guidelines and specifications, repeated surveying at a designated area over time (e.g., construction site with periodic data collection) is not ideal.   This research proposes to develop a comprehensive set of guidelines, specifications, and recommendations for producing survey-grade geospatial products using UAS solutions for applications in preconstruction, construction, and slope sites.  This research is a systematic approach to the implementation of UASs with nonmetric and LiDAR sensors. The produced guidelines, specifications, and recommendations that result from the work will enable this implementation to be accomplished so that accurate and useful data are available. Moreover, the final products will enable the North Carolina Department of Transportation (NCDOT) UAS Utilization Workgroup to develop a department-wide implementation plan.
