Currently the management and administration of buildings in Yellowstone National Park is divided among separate divisions. This coverage will provide the first complete inventory of all the buildings in the park. Differential GPS, heads-up digitizing off 1 meter DOQQs or 7.5 minute DRGs, and georeferenced CADD drawings were all used to obtain building location information. GPS information was corrected using local base station information and exported to a GIS format. All associated attribute information was also verified by an in-field survey.
All polygons have valid labels and attributes.
Polygons digitized off the DOQQs and DRGs have a horizontal accuracy of 12.19 meters. Polygons obtained through GPS can have sub-meter accuracy. The information that populated many of the attributes in this coverage were taken from this report. The information that populated many of the attributes in this coverage were taken from this report. PDOP was set to a maximum of 6, and data were only collected when at least 4 satellites were readable.
