This is a Vector data set. It contains the following vector data types (SDTS terminology):
Horizontal positions are specified in geographic coordinates, that is, latitude and longitude. Latitudes are given to the nearest 0.000001. Longitudes are given to the nearest 0.000001. Latitude and longitude values are specified in Decimal degrees.
The horizontal datum used is D_WGS_1984.
The ellipsoid used is WGS_1984.
The semi-major axis of the ellipsoid used is 6378137.000000.
The flattening of the ellipsoid used is 1/298.257224.

RITA/BTS quality checks the attributes after the shapefile was downloaded. RITA/BTS quality checks were to cross reference the place dataset with the state dataset, to determine that the spatial data and attribute data were accurate. Several records have no state listed in the state column, have inaccurate states associated to the polygon, or their polygons were associated to the wrong state. RITA/BTS found these errors and contributed with building the dataset. RITA/BTS went through the US territories and updated the FIPS code.
Dataset is believed to be 100% complete. Please contact originator with corrections and updates.
The data set is complete but subject to continual updates to reflect boundary amendments, legislation, and acquisitions, and improved processing techniques. The data is being regularly updated with verified boundaries from NPS Land Resources Division. Please contact the data originator with corrections and update suggestions.
Tests for logical consistency are performed by digitizing software (ATLAS*GIS). Each park unit is comprised of one or more polygons.
Are there legal restrictions on access or use of the data?

- To be used for display and general analysis purposes only. These digital national park unit boundaries should not be used for any legal boundary disputes. To obtain the most accurate, current boundary, users should contact the specific park.

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. The data are no better than the original sources from which they were derived. In fact, the data are likely less accurate than the original sources as no attempt has been made to thoroughly error check the data.
