This use of the single photon and Geiger mode lidar for this evaluation is new to the commercial market, according to Woolpert Project Director John Gerhard.
“This technology provides the ability to fly at higher altitudes while acquiring data at an increased point density,” Gerhard said. “The USGS has asked us to provide an evaluation of this sensor technology in support of 3DEP.”
The USGS is developing the 3DEP initiative to respond to the growing need for high-quality topographic data nationwide, to address issues that include flood-risk management, precision agriculture, natural resource management, infrastructure management and hazard mitigation.
Woolpert will then evaluate the data, conduct an accuracy analysis, develop final data products and provide a comprehensive report to the USGS by the end of the year. I hope this will be made public.
