Chesapeake Bay Watershed 2011 Edition Land Cover Data Release

The US Geological Survey Chesapeake Bay Watershed Land Cover Data Series, 2011 edition, (CBLCD-e11) consists of Level I Land Cover data for the years 1984, 1992, 2001, 2006 and 2011. It consists of a series of five 8-bit unsigned integer raster data files of 30 meter spatial resolution in Albers Conic Equal Area projection, NAD83 datum. The 1984 – 2006 data layers were created by aggregating most Level II Anderson classes of the USGS CBLCD Land Cover Data Series released in 2010 (Irani and Claggett, 2010).

USGS 1:1,000,000-Scale Federal Lands of the United States - Parkways and Scenic Rivers 201506 Shapefile

This map layer portrays the linear federally owned or administered land features (i.e., national parkways, wild and scenic rivers, etc.) of the United States and Puerto Rico. Some features may be administered in conjunction with local governments. The map layer was created by extracting and combining linear federal land features from the 1:1,000,000-scale Roads and Streams files that are part of The National Map. There are no Parkways or Scenic Rivers in Hawaii or in the U.S. Virgin Islands.

USGS Small-scale Dataset - 100-Meter Resolution Satellite View with Shaded Relief of the Conterminous United States 201304 GeoTIFF

The Satellite View with Shaded Relief of the Conterminous United States map layer is a 100-meter resolution simulated natural-color image of the United States, with relief shading added to accentuate terrain features. Vegetation is generally green, with forests in darker green and grasslands or shrublands in lighter green. Areas of high reflectance, including urban areas, rock, and dry bare soil, are shown in shades of tan and pink. Very bright areas, such as snow and ice, are light blue. The image was produced by combining a mosaic of Landsat Thematic Mapper (TM) imagery from the Landsat 4 and Landsat 5 satellites with shaded relief generated from 100-meter elevation data extracted from the National Elevation Dataset...

Percent impervious surface for selected Chesapeake Bay watersheds

This dataset contains watershed means of estimated percent impervious surfaces for three time periods: 1992, 2002, and 2012. Estimates are based on coefficients derived from comparing land use of the 2012 NAWQA Wall-to-wall Anthropogenic Land-use Trends (NWALT) product to the 2011 National Land Cover Database (NLCD) imperviousness, then applying those coefficients to previous years (1974-2002) of the NWALT dataset.

USGS Small-scale Dataset - Satellite View of the Conterminous United States, with Shaded Relief 200512 GeoTIFF

The Satellite View of the Conterminous United States, with Shaded Relief map layer is a 200-meter-resolution simulated-natural-color image of the United States. Vegetation is generally green, with forests in darker green and grasslands or shrublands in lighter green. Areas of high reflectance, including urban areas, rock, and dry bare soil, are shown in shades of pink. Very bright areas, such as snow and ice, are colored blue. The image was produced by combining Landsat Thematic Mapper (TM) imagery from the Landsat 4 and Landsat 5 satellites with relief enhanced by shading. This map layer was previously distributed as Satellite View of the Conterminous United States.

USGS Small-scale Dataset - Color Conterminous United States Shaded Relief - 200-Meter Resolution, Albers projection 200603 GeoTIFF

The color conterminous United States shaded relief data were derived from National Elevation Dataset (NED) data, and show the terrain of the conterminous United States at a resolution of 200 meters. The NED is a raster product assembled by the U.S. Geological Survey, designed to provide national elevation data in a seamless form with a consistent datum, elevation unit, and projection. Data corrections made in the NED assembly process minimize artifacts, permit edge matching, and fill sliver areas of missing data. The National Atlas also includes a Lambert Azimuthal Equal Area projection shaded relief file; this file is the same data in an Albers projection.

GAGES-II: Geospatial Attributes of Gages for Evaluating Streamflow

This dataset, termed "GAGES II", an acronym for Geospatial Attributes of Gages for Evaluating Streamflow, version II, provides geospatial data and classifications for 9,322 stream gages maintained by the U.S. Geological Survey (USGS). It is an update to the original GAGES, which was published as a Data Paper on the journal Ecology's website (Falcone and others, 2010b) in 2010. The GAGES II dataset consists of gages which have had either 20+ complete years (not necessarily continuous) of discharge record since 1950, or are currently active, as of water year 2009, and whose watersheds lie within the United States, including Alaska, Hawaii, and Puerto Rico. Reference gages were identified based on indicators that they...

1) Best management practice implementation in the Chesapeake Bay watershed from 1985 to 2014

This metadata record documents 11 comma delimited tables representing the amount of reported best management practice (BMP) implementation for the years from 1985 to 2014 at three geographic scales: county or land-river modeling segment, River Input Monitoring (RIM) station drainage areas, and the entire Chesapeake Bay Watershed (CBWS). Data originated from the Chesapeake Bay Watershed jurisdictions including Maryland, Pennsylvania, Virginia, Delaware, New York, West Virginia, and the District of Columbia. Data were reported to the Chesapeake Bay Program for an annual review of progress toward meeting nitrogen, phosphorus, and sediment reduction goals.
