In 2008, the locations of peak-stage indicators in three short reaches downstream from RM 87 were measured using a handheld GPS unit (see Appendix 1 in the associated USGS-SIR). Total-station measurements were made using an established network of survey control that references the 2011 realization of NAD83 (NAD83 (2011)) (Kaplinski and others, 2017). The measurements were projected into the State Plane Coordinate System of 1983, Arizona central zone (FIPS zone 0202). Vertical positions are provided in both NAD83 ellipsoid heights and in NAVD88 orthometric elevations modeled from GEOID12b.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P9GIQ9ZN", "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.5f31ccca82cee144fb2eace8.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_5f31ccca82cee144fb2eace8", "keyword": ["Grand Canyon", "woody debris", "trash", "surveying", "environment", "USGS:5f31ccca82cee144fb2eace8", "spatial coordinates", "flood history", "river miles", "floods", "driftwood logs", "streamflow", "GPS measurement", "Colorado River", "Arizona", "peak-stage indicators", "field surveys", "pre-dam floods", "river reaches", "elevation", "land surveying", "flow modeling", "field inventory and monitoring", "total-station"], "modified": "2021-06-03T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-112.030, 36.045, -111.615, 36.845", "theme": ["geospatial"], "title": "Surveyed peak-stage elevations, coordinates, and indicator data of strandlines from large floods on the Colorado River in Grand Canyon National Park, Arizona"}
