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.

The SCPN acquired new aerial photography of MEVE through the U.S. Department of Agriculture’s Aerial Photography Field Offi ce (APFO). APFO subcontractor Foto Flight Geomatics, of Tucson, Arizona, acquired the imagery on July 10, 2003, and July 2, 2004. Because of dry and excessively windy conditions during 2003, they did not complete the flights until 2004. The imagery was taken in true color, at a scale of 1:12,000, with 20–40% sidelap and 50–60% overlap. The APFO provided two sets of 9 × 9-in contact prints to the SCPN. The FORT and RMGSC mapping team used the images for reference during polygon delineation and labeling. At project completion, one set of contact prints will reside at MEVE and one at the SCPN. Figure 3.1.2.1 shows the fl ight lines and photo centers.

The U.S. Bureau of Reclamation’s Remote Sensing and GIS Group assisted the SCPN in obtaining DOQQ images through a contract with Horizons Inc., Rapid City, South Dakota. True-color DOQQs at 1:12,000-scale were acquired on September 15, 2003.
