- Entity_and_Attribute_Overview:
-
Three basic attributes are assigned to each park boundary: (1) a unique four character code (ID_); (2) a full park name (NAME1_); and (3) boundary source information (NAME2_). 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 Hovenweep National Monument, the code is the first four letters of the Hovenweep, or HOVE. 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.

To show the location of the boundaries of all six units of the Hovenweep National Monument, located in Utah and Colorado. The intended use of all data in the park's GIS library is to support diverse park activities including planning, management, maintenance, research, and interpretation.

- How were the data generated, processed, and modified?
- Date: Unknown (process 1 of 1)
-
Selected out from the National Park Service boundaries dataset, using ArcView 3.1. Converted to a coverage and reprojected into NAD83 using ArcInfo Workstation 8.2 and ArcGIS 8.1. This boundary was copied into the vegetation geodatabase as the project boundary (stored as a feature class).

This dataset contains 342 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 descriptions; etc.). The boundaries are in Latitude-Longitude (Clarke 1866-NAD27) decimal degrees. The ID_ field contains the unique 4 character park code identifying each park. The NAME1_ field contains the full park name. The NAME2_ field contains information about the source, scale, and date of the boundary. The boundaries are generally the designated boundary. Inholdings may or may not be shown depending on the park. This dataset was originally created in Environmental System's Research Institute's (ESRI) ATLAS*GIS software and is currently maintained in this software. This version of the dataset was created using ESRI's ArcTools 8.0.2 Import to ShapeFile from .AGF file command. To obtain the most accurate, current boundary, users should contact the specific park.
- How well have the observations been checked?
Attributes were verified by visual inspection. Acreage values may differ from published acreage values.
- How accurate are the geographic locations?
The positional accuracy of this dataset has not been formally tested. It has been compared to fence lines collected using GPS technology. These data do not perfectly match one another. Therefore this dataset should not be used in any kind of legal boundary dispute.
- How accurate are the heights or depths?
- Where are the gaps in the data? What is missing?
The dataset is complete, six polygons representing six individual park units within the Hovenweep National Monument.
- How consistent are the relationships among the observations, including topology?
There are no duplicate features present. Polygon features begin and end at the same point. Topology was created by using the build command in ArcInfo Workstation 8.2.
Are there legal restrictions on access or use of the data?
