The Digital Geologic Map of Kenai Fjords National Park and vicinity, Alaska is composed of GIS data layers complete with ArcMap 9.3 layer (.LYR) files, three 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 digital data used to complete this GRI digital dataset were provided by the following: U.S. Geological Survey (Alaska Science Center). Detailed information concerning the sources used and their contribution the GRI product are listed in the Source Citation sections(s) of this metadata record (kefj_metadata.txt; available at http://nrdata.nps.gov/kefj/nrdata/geology/gis/kefj_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 (kefj_geology.mdb), and as shapefile (.SHP) and DBASEIV (.DBF) table files. The GIS data projection is NAD83 Alaska Albers. The data is within the area of interest of Kenai Fjords National Park.
