Synthetic ground control point locations used in photogrammetric processing of approximately 13 km of Big Sur coast from McWay Canyon to Gorda Point, 2017–2023

Published by U.S. Geological Survey | Department of the Interior | Metadata Last Checked: September 11, 2025 | Last Modified: 20250903
This portion of the data release presents locations for the synthetic ground control points (SGCPs) used during the structure-for-motion alignment process in Agisoft Metashape v1.7-2.0. The locations were chosen from lidar flown in early 2018 and then tagged in all imagery where they could be found. Following this procedure the alignment was reoptimized prior to development of the dense point clouds presented in this data release. The data contain the easting, northing, and elevation of the SGCPs taken from the lidar, as well as a description of each location. The data are presented in a comma-delimited text file.
