Digital Geologic Map of the Grand Junction Quadrangle, Colorado (NPS, GRD, GRI, COLM, GRJU digital map) adapted from a U.S. Geological Survey Miscellaneous Field Studies Map by Scott, Carrara, Hood and Murray (2002)
2015. Digital Geologic Map of the Grand Junction Quadrangle, Colorado (NPS, GRD, GRI, COLM, GRJU digital map) adapted from a U.S. Geological Survey Miscellaneous Field Studies Map by Scott, Carrara, Hood and Murray (2002). NPS Geologic Resources Inventory Program. Lakewood, Colorado
The Unpublished Digital Geologic Map of the Grand Junction Quadrangle, Colorado is composed of GIS data layers and GIS tables in a 10.1 file geodatabase (grju_geology.gdb), a 10.1 ArcMap (.MXD) map document (grju_geology.mxd), and individual 10.1 layer (.LYR) files for each GIS data layer, an ancillary map information (.PDF) document (colm_geology.pdf) which contains source map unit descriptions, as well as other source map text, figures and tables, metadata in FGDC text (.TXT) and FAQ (.HTML) formats, and a GIS readme file (grju_gis_readme.pdf). Please read the grju_gis_readme.pdf for information pertaining to the proper extraction of the file geodatabase and other map files. To request GIS data in ESRI 10.1 shapefile format contact Stephanie O’Meara (stephanie.o’meara@colostate.edu; see contact information below). Presently, a GRI Google Earth KMZ/KML product doesn't exist for this map. The data were completed as a component of the Geologic Resources Inventory (GRI) program, a National Park Service (NPS) Inventory and Monitoring (I&M) Division 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. Detailed information concerning the sources used and their contribution the GRI product are listed in the Source Citation section(s) of this metadata record (grju_metadata_faq.html; available at http://nrdata.nps.gov/geology/gri_data/gis/colm/grju_metadata_faq.html). Users of this data are cautioned about the locational accuracy of features within this dataset. Based on the source map scale of 1:24,000 and United States National Map Accuracy Standards features are within (horizontally) 12.2 meters or 40 feet of their actual location as presented by this dataset. Users of this data should thus not assume the location of features is exactly where they are portrayed in ArcGIS or other software used to display this dataset. All GIS and ancillary tables were produced as per the NPS GRI Geology-GIS Geodatabase Data Model v. 2.2. (available at: http://science.nature.nps.gov/im/inventory/geology/GeologyGISDataModel.cfm). The GIS data projection is NAD83, UTM Zone 12N. The data is within the area of interest of Colorado National Monument.
