Ground control point locations for 6 islands in the Oregon Coast National Wildlife Refuge Complex, OR, USA
This portion of the data release presents the locations of the temporary ground control points (GCPs) used for the structure-from-motion (SfM) processing of the imagery collected from a helicopter with a hand-held digital camera on 2024-08-15. For 6 islands (Goat Island, Hunters Island, North Crook Point Rock, Saddle Rock, Whaleshead Cove East, Whaleshead Cove West) 3 temporary ground control points (GCPs) were distributed throughout each island to establish survey control. The GCPs consisted of orange 5-gallon bucket lids (diameter 31.4 centimeters). The GCP positions were measured with an Eos GNSS GPS receiver using real time kinematic (RTK) corrections paired with the Field Maps app. For 4 islands (Meyers Creek East, Meyers Creek West, Unnamed Island 073, Unnamed Island 106), GCPs have yet to be collected and SfM products (DSMs and Orthomosaic images) were generated without precision RTK GPS survey control. The GCP positions are presented in a comma-delimited text file.
