ALT A USGS employee prepares an unmanned aerial vehicle for takeoff as part of the Next Generation Water Observing System (NGWOS) in the Delaware River Basin. This particular drone referred to as "Q-Cam" measures surface water stream velocity. Combined with a second drone, non-contact discharge measurements can be made.
ALT Image of drone flying over water. On top of the image is white line and dark blue space with text that reads “Drone-based mapping”. On the top left is a grey oval outlined in white with text that reads “Research & Development”. Text semi-centered over the image reads “Drone sensors could enhance stream mapping and monitoring”. The USGS logo is on the bottom right of the image.
