This dataset contains geomorphometry for streams and floodplains in the Chesapeake and Delaware River watersheds. Geomorphometry is a quantitative representation of landscape surface form (e.g., channel width and depth) obtained from digital elevation models (DEMs). This dataset contains geomorphometry derived from running 3-m DEMs through the Floodplain and Channel Evaluation Tool (FACET) version 0.1.0. FACET generates shapefiles and rasters of the stream network, cross sections, streambank point locations, floodplain extent, height above nearest drainage (HAND), and reach-scale summaries of bank height, channel width, floodplain width, and a suite of other metrics outlined in the data dictionary. These data were generated to aid in modeling the amount of sediment and nutrients trapped on floodplains or eroded from streambanks in the Chesapeake and Delaware River watersheds.\n\nFiles are organized into folders by hydrologic unit code (HUC) for subbasins within the Chesapeake and Delaware watersheds. Each folder contains the following files within the main folder and a sub folder called \"post processing.\" \n\nXXXX folder, where XXXX is a 4-digit HUC:\nMain [folder_name] files, where \u201cfolder name\u201d is an 8- or 10-digit HUC: \n[folder_name]_bankpixels.tif \n[folder_name]_dem.tif \n[folder_name]_floodplain.tif \n[folder_name]_hand.tif \n[folder_name]_mask.shp \n[folder_name]_network.shp \n[folder_name]_network.tif \n[folder_name]_channel_xns.shp \n\nPost-processing folder files:\nbankpoints_1D_metrics.shp \nbankpoints_1D_metrics_all_stats.dbf \nchannel_floodplain_2D_metrics.shp \nchannel_floodplain_2D_metrics_all_stats.dbf \nfloodplain_xns_1D_metrics.shp \nfloodplain_xns_1D_metrics_all_stats.dbf \n\nEach file and associated attributes are described in the data dictionary listed in the Attached Files section. Merged files spanning the entire study area are included within the Child Item page called Chesapeake and Delaware Basin Combined Files. The combined files include a shapefile with the stream network and the floodplain extent, as well as a post-processing table with select stream and floodplain metrics.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P9RQJPT1", "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.5cae39c3e4b0c3b00654cf57.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_5cae39c3e4b0c3b00654cf57", "keyword": ["Chesapeake Bay watershed", "Delaware", "Delaware River Basin", "District of Columbia", "Maryland", "New Jersey", "New York", "Pennsylavania", "USGS:5cae39c3e4b0c3b00654cf57", "Virginia", "West Virginia", "ecosystem service", "floodplain", "geomorphology", "geospatial", "lidar", "mapping", "remote sensing", "river", "stream", "streambank"], "modified": "2020-04-28T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-80.540992, 36.669419, -74.357422, 42.987332", "theme": ["geospatial"], "title": "Geomorphometry for Streams and Floodplains in the Chesapeake and Delaware Watersheds"}
