What does this data set describe?
    Title:
    Unpublished Digital Geologic-GIS Map of Hovenweep National Monument, Colorado and Utah (NPS, GRD, GRI, HOVE, HOVE digital map) adapted from Geologic Resources Inventory unpublished mapping by Poole (2000), and a U.S. Geological Survey Map by Haynes, Vogel and Wyant (1972)
    Abstract:
    The Unpublished Digital Geologic-GIS Map of Hovenweep National Monument, Colorado and Utah is composed of GIS data layers and GIS tables in a 10.1 file geodatabase (hove_geology.gdb), a 10.1 ArcMap (.MXD) map document (hove_geology.mxd), individual 10.1 layer (.LYR) files for each GIS data layer, an ancillary map information (.PDF) document (hove_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 (hove_gis_readme.pdf). Please read the hove_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.omeara@colostate.edu; see contact information below). The data is also available as a 2.2 KMZ/KML file for use in Google Earth, however, this format version of the map is limited in data layers presented and in access to GRI ancillary table information. Google Earth software is available for free at: <http://www.google.com/earth/index.html>. Users are encouraged to only use the Google Earth data for basic visualization, and to use the GIS data for any type of data analysis or investigation. 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: National Park Service Geologic Resources Inventory and 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 (hove_metadata_faq.html; available at <http://nrdata.nps.gov/geology/gri_data/gis/hove/hove_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 (127 meters or 416.7 feet for structure contour lines and uranium prospects) 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 Google Earth, 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. 2.3. (available at: <http://science.nature.nps.gov/im/inventory/geology/GeologyGISDataModel.cfm>). The GIS data projection is NAD83, UTM Zone 12N, however, for the KML/KMZ format the data is projected upon export to WGS84 Geographic, the native coordinate system used by Google Earth. The data is within the area of interest of Hovenweep National Monument.

  2. How were the data generated, processed, and modified?

    Date: 14-Jul-2016 (process 1 of 1)
    1.) GIS features were digitized from a TIF image of the source maps scanned at 300dpi and georeferenced in NAD83 UTM coordinates. See the Source Information Contribution section(s) for specific source map details. Geology features were initially digitized into GRI data model compliant coverages. 2.) Line quality was checked against the source scan to ensure that GIS features were represented accurately, both positionally and spatially. 3.) Feature attribution was derived using the source map. 4.) Features were migrated (data loaded) to a file geodatabase in the GRI geodatabase data model version 2.3. For details on the GRI data model see the NPS GRI Geology-GIS Geodatabase Data Model v. 2.3 (available at: <http://science.nature.nps.gov/im/inventory/geology/GeologyGISDataModel.cfm>). 5.) Features from all component quadrangle maps were then data loaded into a compiled map geodatabase, 6.) Data Model topology rules were then validated for all features and any topology errors corrected. 7.) Quality control (QC) consisting of a visual check of the data against its source, as well as running a GRI developed ArcObjects tool to check for GRI data model validation and feature-related consistency, was conducted. 8.) The UNIT and MAP tables were populated and checked against the source (s). Relationship classes were also added and used to ensure attribution consistency between feature class and table attribution. 9.) Feature symbology was produced for all feature classes. An attempt was made to best match symbology to its source map, however, in some cases feature symbology maybe slightly modified, primarily based on the limitations of the ArcGIS geology style. In some cases, however, symbology may have been modified to reconcile differences from multiple sources. 10.) GIS feature classes were exported from the geodatabase to shapefile (SHP) format, and GIS tables exported to DBASEIV (DBF) format. Layer (LYR) files were also exported. 11.) The ancillary map information PDF document, see the Supplemental Information section for additional information, was produced from textual information and figures present on the source map(s) and/or in digital data files. If applicable, source map images were produced at 150dpi or greater resolution and optical character recognition (OCR) software was used to produce text from source map text. The text, source map images and other ancillary source map information were added to a Help & Manual (.HMXZ) template file. The HMXZ file was then compiled to produce the ancillary map PDF document. Any compilation errors were checked and corrected and the document was reviewed for content, usability and grammatical errors. 12.) KML/KMZ files were produced with certain UNIT and MAP table fields appended and calculated for each feature class prior to export.

How reliable are the data; what problems remain in the data set?
  1. How well have the observations been checked?

    Feature and table attribution was derived and checked with the source map(s). Attribution was checked (QCd) for errors. Users of this data are advised to FULLY and CAREFULLY READ the "DISTRIBUTION LIABILITY" section of this metadata before using the data.

  2. How accurate are the geographic locations?

    Data was digitized from a georeferenced source map .TIF image(s) (300dpi) produced from scanned maps. Users of this data are cautioned about the locational accuracy of features within this dataset. Based on the source map scale and United States National Map Accuracy Standards features are within (horizontally) 12.2 meters or 40 feet (127 meters or 416.7 feet for structure contour lines and uranium prospects) 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 portrayed are in Google Earth, ArcGIS or other software used to display this dataset. The PRECISION of any Shapefile (.SHP) files is DOUBLE. Coordinate tics on the georeferenced (registered and rectified) source map image(s) were checked against control points that had the exact specified coordinates of the tic. The direct distance between the image tic and its control point were measured. All measured distances were less than 50% of the required distance to meet National Map Accuracy Standards (1/50th of an inch for maps at 1:20,000 scale and smaller). Features was checked (QCd) after digitizing for positional accuracy errors using the georeferenced source map image.

  3. How accurate are the heights or depths?

    No vertical coordinates are present in this GRI digital dataset.

  4. Where are the gaps in the data? What is missing?

    All data is considered complete to the extent of the source map(s).

  5. How consistent are the relationships among the observations, including topology?

    GIS data in 10.1 file geodatabase and 2.2 KML/KMZ file formats.

How can someone get a copy of the data set?
Are there legal restrictions on access or use of the data?

Access_Constraints: None
Use_Constraints:
Not for use at scale greater than 1:24,000 (source map scale). Users of this data are cautioned about the locational accuracy of features within this dataset.
