Imagery data for the Vegetation Mapping Inventory Project of Cedar Breaks National Monument

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 mapping units 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. A combination of methods was used to delineate and interpret vegetation polygons for the mapping component of the CEBR project area, including the use of ERDAS Imagine software facilitated by heads-up (on-screen) digitizing. The project used the program standard minimum mapping unit of 0.5 ha (1.24 acres) with few exceptions.
