Digital Geologic Map of Chesapeake and Ohio Canal National Historical Park and Vicinity, District of Columbia, Virginia, Maryland and West Virginia (NPS, GRD, GRI, CHOH, CHOH digital map)

Description

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.
