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. Photointerpreters delineated initial polygons through manual interpretation of 2003/2004 1:12,000-scale true color aerial photography supplemented by occasional computer screen digitizing on a mosaic of digitized aerial photos. These polygons were labeled with base map classes during photointerpretation. Field visits verified interpretation concepts.

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. Vegetation and land use were interpreted to as detailed a level as possible from high-resolution, 9” x 9” stereo pairs of 1:12,000-scale true color aerial photography. Polygons representing vegetation or land use map classes were delineated on Mylar overlays on aerial photographs (where signatures were confusing) and with the heads-up digitizing technique (where signatures had high contrast), then transferred to a spatial database. The project used the national program standard minimum mapping unit of 0.5 ha with few exceptions.

Vegetation and land use were interpreted to as detailed a level possible from high-resolution, 9” x 9” stereo pairs of 1:12,000-scale true color aerial photography. Polygons representing vegetation or land use map classes were delineated directly on-screen through heads-up digitizing using ArcGIS editing tools and transferred to a spatial database. The project used the program standard minimum mapping unit of 0.5 ha with few exceptions.

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. Vegetation and land use were interpreted from high-resolution, true color digital orthoimagery and 9” x 9” stereo pairs of 1:12,000-scale true color photographs flown specifically for this project. Polygons representing vegetation or land use map classes defined by RMGSC, in consultation with other project partners, were delineated on orthophotos in a digital environment. With few exceptions, occurrences smaller than approximately 0.5 ha were not delineated.

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 imagery we used was acquired by Digital- Globe Inc.’s Quickbird satellite on December 3, 2007, as a new, tasked acquisition for this project. Image preprocessing and initial interpretation to the formation level were done at the Arizona Remote Sensing Center, University of Arizona. The imagery product purchased was the “Ortho-ready Standard” bundle of four spectral bands (blue, green, red and near-infrared) at 2.4-m spatial resolution, plus the broadband panchromatic data at 0.6-m resolution. This imagery is intended to be orthorectified by the user and is only coarsely geo-registered, with a nominal spatial accuracy of 23 m CE90—meaning that 90% of features in the imagery must be within 23 meters of their true location on the ground.
