Photogrammetric data collected by small unoccupied aircraft system for vegetation analysis at three study reaches along the Verde River, Arizona, December 2017

The U.S. Geological Survey collected low-altitude airborne visual imagery via a multirotor, small unoccupied aircraft system (sUAS) along with Real Time Kinematic (RTK) GPS survey data at three study sites (Beasley Flat, Childs, and Sheep Bridge) along the Verde River in Arizona in December 2017. Visual imagery was collected in jpg format and Structure from Motion techniques were applied to the visual imagery to derive a time-specific high-resolution orthomosaic for each of the three study sites.
