The basis for these features is the Willamette Flood Insurance Study \u2013 \nPhase One (2013). The hydraulics and hydrology for the FIS were reused in the production of these polygons; \nthe reports and information associated with the FIS are applicable to this product. The Digital Elevation Model \n(DEM) utilized for the Willamette FIS submittal was produced by combining multiple overlapping topographic \nsurveys for the Middle Fork and Coast Fork of the Willamette River. This DEM was created from four sources: \nLiDAR of the Springfield area that was flown in 2008, LiDAR of Silk Creek that was flown in 2011, LiDAR of \nFall Creek that was flown in 2012, and photogrammetry of the Middle Fork and Coast Fork of the Willamette \nRiver that was flown in 2004. In areas where no high-resolution elevation data were available, USGS National \nElevation Dataset (NED) data were used to supplement the DEM. The shapefiles Hi_Res_Extents.shp and \nLow_Res_Extents.shp define the limits of these areas. The horizontal datum of the DEM is NAD 1983 State \nPlane-Oregon South HARN with units of International Feet (NAD83). The vertical datum of the elevation model \nis NAVD 1988 with units of international feet (NAVD-88). In addition, some areas show surveyed bathymetry \nwithin the channel. 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 time of the \naerial data collection. Bridge decks are generally removed from DEMs as standard practice. Therefore, these \nfeatures may be shown as inundated when they are not. An effort to clip flood extents on bridge decks was \nmade, but judgement should be used when estimating the usefulness of a bridge during flood flow. Comparing \nthe bridge to the surrounding ground can be more informative in this respect than simply looking at the bridge \nitself. The features and depth grids stop as the Coast Fork approaches the Middle Fork on the northern end \nof the reach.See cfwgoshOR.shp for information regarding this file. This represents the depth grid for the 39,900 \nprofile.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P9ANPJMD", "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.03a63300-4e2e-4ec9-a20c-e9666637fef6.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_03a63300-4e2e-4ec9-a20c-e9666637fef6", "keyword": ["Coast Fork Willamette River", "Creswell", "Goshen", "Oregon", "USGS:03a63300-4e2e-4ec9-a20c-e9666637fef6", "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_6: Flood Inundation Depth for a Flow of 39,900 at the Gage Coast Fork Willamette River at Goshen, Oregon"}
