GIS representation of Chesapeake's corporate boundary. Not official.

This data set contains small-scale base GIS data layers compiled by the National Park Service Servicewide Inventory and Monitoring Program and Water Resources Division for use in a Baseline Water Quality Data Inventory and Analysis Report that was prepared for the park. The report presents the results of surface water quality data retrievals for the park from six of the United States Environmental Protection Agency's (EPA) national databases: (1) Storage and Retrieval (STORET) water quality database management system; (2) River Reach File (RF3) Hydrography; (3) Industrial Facilities Discharges; (4) Drinking Water Supplies; (5) Water Gages; and (6) Water Impoundments. The small-scale GIS data layers were used to prepare the maps included in the report that depict the locations of water quality monitoring stations, industrial discharges, drinking intakes, water gages, and water impoundments. The data layers included in the maps (and this dataset) vary depending on availability, but generally include roads, hydrography, political boundaries, USGS 7.5' minute quadrangle outlines, hydrologic units, trails, and others as appropriate. The scales of each layer vary depending on data source but are generally 1:100,000.

The Digital Geologic Map of Chesapeake and Ohio Canal National Historical Park and Vicinity, District of Columbia, Virginia, Maryland and West Virginia is composed of GIS data layers complete with ArcMap 9.3 layer (.LYR) files, two ancillary GIS tables, a Map PDF document with ancillary map text, figures and tables, a FGDC metadata record and a 9.3 ArcMap (.MXD) Document that displays the digital map in 9.3 ArcGIS. The data were completed as a component of the Geologic Resources Inventory (GRI) program, a National Park Service (NPS) Inventory and Monitoring (I&M) funded program that is administered by the NPS Geologic Resources Division (GRD). Source geologic maps and data used to complete this GRI digital dataset were provided by the following: U.S. Geological Survey and Maryland Geological Survey. Detailed information concerning the sources used and their contribution the GRI product are listed in the Source Citation sections(s) of this metadata record (choh_metadata.txt; available at http://nrdata.nps.gov/choh/nrdata/geology/gis/choh_metadata.xml). All GIS and ancillary tables were produced as per the NPS GRI Geology-GIS Geodatabase Data Model v. 2.1. (available at: http://science.nature.nps.gov/im/inventory/geology/GeologyGISDataModel.cfm). The GIS data is available as a 9.3 personal geodatabase (choh_geology.mdb), and as shapefile (.SHP) and DBASEIV (.DBF) table files. The GIS data projection is NAD83, UTM Zone 18N. The data is within the area of interest of Chesapeake and Ohio Canal National Historical Park, as well as Antietam National Battlefield, Harpers Ferry National Historical Park, and George Washington Memorial Parkway.

This layer represents the boundary of the Chesapeake Bay watershed. The Chesapeake Bay is the largest estuary in the U.S. and supports roughly 3,600 species of plants and animals, including 348 species of finfish, 173 species of shellfish, and 2,700 species of plants. Nearly one million waterfowl winter on and near the bay – approximately one-third of the Atlantic Coast’s migratory population. The birds stop to feed and rest during their annual migration along the Atlantic Flyway.This boundary was extracted from the USGS Watershed Boundary Dataset using the hydrologic unit codes (HUCs) by the US Fish and Wildlife Service for use in the Chesapeake Watershed Investments for Landscape Defense Program, known as Chesapeake WILD. For more information on Chesapeake WILD visit https://www.fws.gov/program/chesapeake-wild. HUCs have two to eight digit numbers based on the four levels of classification in the hydrologic unit system. The Chesapeake Bay watershed is delineated in the HUC 4 (four digit) layer. For more information about hydrologic units visit https://water.usgs.gov/GIS/huc.html.

The dataset contains locations and attributes of HUC-11 watersheds. The USGS presents a detailed explanation of HUCs at https://water.usgs.gov/GIS/huc.html. HUC-11 boundaries are compiled by each state. The export files of HUC-11 at the state level were provided by each respective state and are unmodified. HUC-11 boundaries for Delaware are not yet available. Also, a small portion of the Chesapeake Basin in NY State has not yet been completed.

Open the Data Resource: https://gis.chesapeakebay.net/server/rest/services/ChesapeakeProgress/cpFish_Passage_Streams_Opened/MapServer/1 This Chesapeake Bay Program indicator of progress toward the Fish Passage Outcome shows the fish passages that were installed after the 2011 baseline in order to open rivers and streams to targeted migratory and resident fish species (e.g., brook trout, eels, river herring and shad). Data were obtained from mulitple state and federal sources and edited by The Nature Conservancy for use in the Northeast Aquatic Connectivity project and in Chesapeake fish passage prioritization. These data were "snapped" to the U.S. Geological Survey's high-resolution (1:24,000) National Hydrography Dataset, so that dam points are geometrically coincident with stream lines. The data underwent several quality control checks to help ensure dams are in the proper location.

Benthic data were aggregated from multiple sources to create a baywide record of seabed material in the Chesapeake Bay. Habitat polygons are classified with an adaptation of the Coastal and Marine Ecological Classification Standard (CMECS) Substrate Component (SC). Source data were collected during the interval 1842-2014. Because of potential temporal changes in bottom conditions and deficiencies in survey methodology, benthic habitat characterizations may be in error in some areas. These are, however, the best data currently available.This is a subset of an original dataset which may be found here: http://ftp.ncbo.cgclientx.com/ecoscience/Chesapeake_Bay_Coastal_and_Marine_Ecological_Classification_Standard_CMECS/Metadata/MD_Bay_Bottom_Survey/.

These data provide an accurate high-resolution shoreline compiled from imagery of PUNGOTEAGUE CREEK TO CHESAPEAKE BAY BRIDGE-TUNNEL, VA . This vector shoreline data is based on an office interpretation of imagery that may be suitable as a geographic information system (GIS) data layer. This metadata describes information for both the line and point shapefiles. The NGS attribution scheme 'Coastal Cartographic Object Attribute Source Table (C-COAST)' was developed to conform the attribution of various sources of shoreline data into one attribution catalog. C-COAST is not a recognized standard, but was influenced by the International Hydrographic Organization's S-57 Object-Attribute standard so the data would be more accurately translated into S-57.
