The basis for these features is the Willamette Flood Insurance \nStudy \u2013 Phase One (2013). The hydraulics and hydrology for the FIS were reused in the production of \nthese polygons; the reports and information associated with the FIS are applicable to this product. The \nDigital Elevation Model (DEM) utilized for the Willamette FIS submittal was produced by combining \nmultiple overlapping topographic surveys for the Middle Fork and Coast Fork of the Willamette River. \nThis DEM was created from four sources: LiDAR of the Springfield area that was flown in 2008, LiDAR \nof Silk Creek that was flown in 2011, LiDAR of Fall Creek that was flown in 2012, and photogrammetry \nof the Middle Fork and Coast Fork of the Willamette River that was flown in 2004. In areas where no \nhigh-resolution elevation data were available, USGS National Elevation Dataset (NED) data were used \nto supplement the DEM. The shapefiles Hi_Res_Extents.shp and Low_Res_Extents.shp define the \nlimits of these areas. The horizontal datum of the DEM is NAD 1983 State Plane-Oregon South HARN \nwith units of International Feet (NAD83). The vertical datum of the elevation model is NAVD 1988 with \nunits of international feet (NAVD-88). In addition, some areas show surveyed bathymetry within the \nchannel. These can be noted by the sharp increase in apparent depth, creating a stripe across the \ndepth grid when compared to the LiDAR data, which represents the water surface elevation at the \ntime of the aerial data collection. Bridge decks are generally removed from DEMs as standard practice. \nTherefore, these features may be shown as inundated when they are not. An effort to clip flood extents \non bridge decks was made, but judgement should be used when estimating the usefulness of a bridge \nduring flood flow. Comparing the bridge to the surrounding ground can be more informative in this respect \nthan simply looking at the bridge itself. The features and depth grids stop as the Coast Fork approaches \nthe Middle Fork on the northern end of the reach. See cfwgoshOR.shp for information regarding this file. \nThis represents the depth grid for the 46,800 cfs profile.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P93TLJ9G", "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.c5e8806e-9433-402b-a649-6ebfce65e849.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_c5e8806e-9433-402b-a649-6ebfce65e849", "keyword": ["Coast Fork Willamette River", "Creswell", "Goshen", "Oregon", "USGS:c5e8806e-9433-402b-a649-6ebfce65e849", "Willamette Valley", "elevation", "environment", "flood", "flood-inundation maps", "flooded area", "geoscientificInformation", "geospatial analysis", "high-water marks", "inlandWaters", "river/stream"], "modified": "2020-11-17T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-123.048840045, 43.909466547, -122.949900456, 44.011530659", "theme": ["geospatial"], "title": "SIR2016-5029_cfwgoshor_7: Flood Inundation Depth for a Flow of 46,800 cfs at the Gage Coast Fork Willamette River at Goshen, Oregon"}
