Twenty temporary ground control points (GCPs) consisting of small square tarps with black-and-white cross patterns were distributed throughout the area to establish survey control. The GCP positions were measured using real-time kinematic (RTK) GPS, using corrections from a GPS base station located on a benchmark designated SFML, located approximately 1 kilometer from the study area. The GCP positions are presented in a comma-delimited text file.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P9J9CHOH", "description": "Landing page for access to the data", "format": "XML", "mediaType": "application/http", "title": "Digital Data"}, {"@type": "dcat:Distribution", "description": "The metadata original format", "downloadURL": "https://data.usgs.gov/datacatalog/metadata/USGS.638a95ced34ed907bf79095e.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_638a95ced34ed907bf79095e", "keyword": ["Bathymetry and Elevation", "CHMRP", "Carmel River", "Coastal and Marine Hazards and Resources Program", "Monterey County", "PCMSC", "Pacific Coastal and Marine Science Center", "SfM", "State of California", "Structure-from-motion", "U.S. Geological Survey", "UAS", "USGS", "USGS:638a95ced34ed907bf79095e", "Unmanned aerial system", "aerial and satellite photography", "aerial photography", "altimetry", "elevation", "geomorphology", "geoscientificInformation", "geospatial datasets", "image mosaics", "orthophotography", "photography", "remote sensing", "structure from motion", "topographic maps", "topography"], "modified": "2023-01-11T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-121.66731, 36.37326, -121.66118, 36.38117", "theme": ["geospatial"], "title": "Ground control point locations for the UAS survey of the Los Padres Reservoir delta, Carmel River valley, CA, 2017-11-01"}
