Zion National Park 20020801 vector digital data http://www1.usgs.gov/vip/zion/zionbdy.zip doi:10.5066/F7DV1GVB This is an Arc/Info coverage containing one polygon representing the boundary (current as of April 2002) of Zion National Park, Utah. This coverage is in NAD 83. This dataset representing the boundary of Zion National Park is used to determine land ownership, shared boundaries, and fencelines. This coverage is also used in almost all map compositions created in the park, showing the extent of Zion National Park, Utah. It is important to note that this dataset may appear to be inaccurate when compared to topographic maps and DLG's, but that it is, in fact, the most accurate available coverage for the Zion National Park boundary. This dataset has been updated with data from the BLM's GCDB (Geographic Coordinate Data Base), GPS locations of BLM monuments, and coordinates derived from certified land surveys. This dataset also includes all boundary changes up to the date of the dataset (April 2002); no further changes occured between that date and the metadata date (August 2002). This coverage was created using NAD 27 and converted to NAD 83 in early 2002. The conversion to NAD 83 is to adhere to NPS spatial guidelines. 20020801 observed Complete As needed Zion National Park and environs -113.229572 -112.860781 37.509871 37.135824 None Land Ownership Boundary Park Boundary land ownership None Zion National Park Utah Southwest Desert North America NPS USA United States National Park Service Washington County None None Zion National Park, National Park Service GIS Specialist mailing and physical address

This coverage has been minimally attributed; REV-DATE, ACRES, and NAME are the user-defined attributes. The remaining five attributes are Arc/Info default attributes which are computed internally by the software. This dataset was processed following Zion National Park, GIS Program Standards. These standards verify that every dataset created in, imported to, and exported from the park adheres to certain processing standards that are FGDC compliant. This coverage was revised in August 2000 to reflect corrections to the boundary and is now considered 100% complete. This is the most accurate available data for the park boundary, and is based on GPS points, Public Land Survey System, and surveyors' (BLM Cadastral) coordinate data. Accuracy is tested by visual and measured comparisons of DOQ's, GPS features, and other source data geospatial datasets. This is the most accurate available data for the park boundary, and is based on GPS points, Public Land Survey System, and surveyors' coordinate data. Bureau of Land Management, Cadastral Division Unknown map This data consisted of a listing of geographic coordinates for boundary changes and corrections (for accuracy), a legal description of the boundary change (land acquired in a land swap which occurred in 1997), and maps depicting the areas involved in the land swap. This data was received at Zion from the BLM on 10/10/1997. The date of the original survey from which the coordinates were derived, is unknown. For details on the Cadastral data used in creating this coverage, contact Larry Judd at the BLM Cadastral Division; 176 East D.L. Sargent Dr., Cedar City, UT 84720; 435/865-3016. certified surveyor data (Microsoft Word document) Unknown the publication date certified surveyor's data Provided coordinates used with the Arc/Info GENERATE command to create vectors for park boundary; also provided legal descriptions for newly acquired land.

Zion National Park 1996 database 24000 digital database file 1996 the publication date GPS data Provided GPS coordinates for locations along the park boundary. Inaccuracies and discrepancies in the boundary coverage were discovered and corrected between 1996 and 1999; in addition, a land swap which necessitated a boundary change occurred in 1997. Corrections and updates were made as follows: Segments of the Zion National Park boundary were GPSed when possible. In some areas of the park the geographical terrain is so extreme that using GPS to obtain the boundary would be impossible. The remaining segments of the boundary were taken from certified surveyors' data and the Geographic Coordinate Data Base (GCDB). A series of digitized segments were snapped to these points, while the GPSed sections remained unedited. The boundary was then verified and tested in Arcedit for discrepancies and errors. certified surveyor's data GCDB GPS data 19990809 Zion National Park, National Park Service GIS Specialist mailing and physical address

ACRES = the number of acres of the polygon. Arc/Info automatically calculates polygon areas in square meters as the default. This number was divided by 4046.8564 (square meters per acre) to obtain the figure for acres. This coverage consists of one polygon which represents the entire park, and its area is 148,02951129 acres. NAME = Zion National Park. The coverage consists of one polygon representing the park as a whole.
