Imagery data for the Vegetation Mapping Inventory Project of Zion National Park
Description
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.
Horizons, Inc. (Rapid City, SD) flew true-color aerial photography for ZION at scales of 1:12,000 and 1:40,000 on June 22 and 23, 1999. We chose true-color film because of its ability to penetrate shadows allowing shapes of vegetation to be discerned through dim light. At the 1:40,000 scale, Horizon’s exposed approximately 135 frames along 16 flightlines to cover the project area. The digital mosaic was then magnified to 1:12,000 and rectified or corrected through a mathematical process that warps and stretches the image between known control points.
