UAS-based LiDAR for Pre-Construction Survey and Transportation Applications
Transportation professionals continually look for advanced technologies to reduce overall survey costs, staff time in the field, and reduce risk to staff in high traffic volume situations. There is a significant increase in the use of unmanned aircraft systems (UAS) to support the capture of highly accurate terrain models, especially in areas of dense vegetative cover or unstable topographic (geohazard) conditions. This presentation will discuss the technology available and what systems and sensors are currently being utilized to meet DOT data accuracy standards. Additionally, we will cover several State DOT case studies for performing UAS-based pre-construction design and Geohazard surveys.
