Boundary FAQ Metadata

Frequently-anticipated questions:


What does this data set describe?

    Title: National Park System Boundary Dataset
    Abstract:
    This dataset contains 340 National Park System unit boundaries. Under the jurisdiction of the National Park Service (NPS), these park units are located throughout the United States (U.S.) and its territories. Almost all the parks are located north of the equator in the western hemisphere; although a couple parks are south of the equator or in the eastern hemisphere. The dataset was compiled (and edited) from a variety sources: park-based GIS databases; U.S. Geological Survey 7.5' 1:24,000 quadrangles; NPS Park Land Status Maps; legal.

  1. How should this data set be cited?

  6. How does the data set represent geographic features?

    1. How are geographic features stored in the data set?

      This is a Vector data set.

    2. What coordinate system is used to represent geographic features?

      Grid_Coordinate_System_Name: Universal Transverse Mercator
      Universal_Transverse_Mercator:
      UTM_Zone_Number: 13
      Transverse_Mercator:

      Latitude_of_Projection_Origin: 0
      False_Easting: 0
      False_Northing: 0
      Scale_Factor_at_Central_Meridian: .9996

      Planar coordinates are encoded using coordinate pair
      Abscissae (x-coordinates) are specified to the nearest 1
      Ordinates (y-coordinates) are specified to the nearest 1
      Planar coordinates are specified in meters

      The horizontal datum used is North American Datum of 1927.
      The ellipsoid used is Clarke 1866.
      The semi-major axis of the ellipsoid used is 6378137.
      The flattening of the ellipsoid used is 1/298.257.

  7. How does the data set describe geographic features?

    Entity_and_Attribute_Overview:
    Three basic attributes are assigned to each park boundary: (1) a unique four character code; (2) a full park name; and (3) boundary source information. The four character code is generally a combination of the first two letters of the first two words in a park's name (or the first four letters if the park has a one word name). For example, Yosemite National Park is YOSE while Rocky Mountain National Park is ROMO. The park's full name is the actual given name of the park. The boundary source information provides the date, scale, and originator of the particular park boundary.
    Entity_and_Attribute_Detail_Citation: NA

Why was the data set created?

These digital park unit boundaries should not be used for any legal boundary disputes. They are intended solely for use only in identifying the general locations of national park units throughout the U.S. This dataset was compiled to assist the NPS Water Resources Division in determining the proximity of certain hydrographic features to national park units and whether national park units are contained in other management units.


How was the data set created?

  1. From what previous works were the data drawn?

    NPSWRDPARKBDYSVer.2 (source 1 of 1)
    National Park Service, Water Resources Division, 199904, National Park System Boundary Dataset.

    Type_of_Source_Media: electronic file
    Source_Contribution: National park unit designated boundaries.

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

    Date: 1992 (process 1 of 1)
    This national park boundaries dataset was compiled by combining park boundaries from a variety of sources: extant digital park-based GIS databases; analog U.S. Geological Survey 7.5' 1:24,000 quadrangles; analog NPS Park Land Status Maps; legal descriptions; etc.). Digital boundaries from existing park GIS databases were converted to ATLAS*GIS format and thinned as necessary to reduce the number of points describing the boundary to a maximum of 4,096. Analog boundaries from the U.S. Geological Survey 7.5' 1:24,000 quadrangles and from NPS Park Land Status Maps were digitized in ATLAS*GIS and directly incorporated into the master dataset.

  3. What similar or related data should the user be aware of?


How reliable are the data; what problems remain in the data set?

  1. How well have the observations been checked?

    The attribute accuracy was tested by manual comparison of the source with hard copy printouts. Attributes were further verified by visual inspection.

  2. How accurate are the geographic locations?

  3. How accurate are the heights or depths?

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

    Dataset contains boundaries for only 1 of 375 park units. Park boundaries are generally the legislative boundary only. No attempt has been made to include or exclude inholdings within the designated boundary.

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

    Tests for logical consistency are performed by digitizing software (ATLAS*GIS).


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:
This digital national park unit boundary should not be used for any legal boundary disputes. To obtain the most accurate, current boundary, users should contact the specific park. The National Park Service shall not be held liable for improper or incorrect use of the park boundary data described and/or contained herein. These data are not legal documents and are not intended to be used as such. The information contained in these data is dynamic and may change over time.
