The files linked to this reference are the geospatial data created as part of the completion of the baseline vegetation inventory project for the NPS park unit. Current format is ArcGIS file geodatabase but older formats may exist as shapefiles. For four of the map units – 3-SDF, 4-SDAF, 27-POHV, and 31-LBY – modeling using GIS principles was also employed. Modeling involves using environmental conditions of a map unit, such as elevation, slope, and aspect, which were determined by the field-collected ecological data. Data satisfying these conditions were obtained from ancillary data sources, such as USGS DEM data. These data were fed into a model that will result in locations (pixels) where all the desired conditions exist. For example, if a certain map unit was a shrubland that predominantly occurs above 8000 feet, on slopes of 3-10%, and on west-facing aspects, the correctly-constructed model will output only locations where this combination of conditions will be found. The resulting areas were then examined manually with the traditional photo interpretation process to confirm that they indeed could be accepted as that map unit. If photo interpretation determines that the areas were not acceptable, then they were changed to a more appropriate map unit.

This reference contains the imagery data used in the completion of the baseline vegetation inventory project for the NPS park unit. Orthophotos, raw imagery, and scanned aerial photos are common files held here.\ Natural color aerial photographs were acquired from three different photo missions between 1995 and 1997. A total of 13 photos along three flight lines were used. The photo missions cover the entire project area, which includes the entire park and environs. Skytech Aero, Inc. (North Little Rock, AR) took aerial photographs for the western portion of the project on August 27, 1995. The photos were taken at a flight height of approximately 13,000 feet with a Jena MRB 15/2323 camera using color negative film. The scale of the 9 x 9-inch paper prints was approximately 1:26,500. Skytech Aero, Inc. (North Little Rock, AR) took aerial photographs for the central portion of the project on September 5, 1996. The photos were taken at a flight height of approximately 12,000 feet with a Jena MRB 15/2323 camera using color negative film. The scale of the 9 x 9-inch paper prints was approximately 1:23,700. Skytech Aero, Inc. (North Little Rock, AR) took aerial photographs for the eastern portion of the project on September 28, 1997. The photos were taken at a flight height of approximately 11,000 feet with a Jena MRB 15/2323 camera using color negative film. The scale of the 9 x 9-inch paper prints was approximately 1:22,000. Two sets of ancillary aerial photography were used as collateral information. The first was a set of CIR paper prints. Intrasearch (12424 E Weaver Place, Ste 100, Englewood, CO 80111) took aerial photographs on August 9, 1983. The photos were taken at a flight height of 12,000 feet above mean ground level with a RC8 camera using Kodak 2443 Infrared film. The scale of the 9 x 9-inch paper prints was approximately 1:24,000. The second ancillary photography was a set of black-and-white paper prints. Rocky Mountain Aerial Surveys, Inc (14 Inverness Drive East, Building G-136, Englewood, CO 80111-6406) took aerial photographs on October 18,1997. The photos were taken at a flight height of 6000 feet above mean ground level with a Zeiss RMKA/15/23 camera using Kodak 2405 XX Black and White film. The scale of the 9 x 9-inch paper prints was approximately 1:12,000. Other source information supplied by the NPS includes (all digital): the park boundary, surficial geology, soils, and noxious weeds. The USGS supplied Digital Raster Graphic data (DRG), Digital Elevation Model data (DEM), and Digital Orthophoto data (DOQ). Slope and aspect data was derived from the DEM.
