Imagery data for the Vegetation Mapping Inventory Project of Knife River Indian Villages National Historic Site
2002. Imagery data for the Vegetation Mapping Inventory Project of Knife River Indian Villages National Historic Site
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 aerial photo contract to Horizons, Incorporated of Rapid City, South Dakota was for the acquisition of color aerial photography for KNRI and vicinity at the standard 1:12,000 scale photography typically used for photointerpretation. Photographs were acquired June 20, 2002. The project area is covered by x 1:12,000 scale photos and 2 flightlines. A total of 22 color photographs were taken at 1:12,000 (1"=1,000') scale and printed on 9"x9" stock. Overlap for these photos were approximately 50-60% and sidelap between flight lines was approximately 20-30%. After receiving the aerial photography from the contractor, all distinguishing ground features were delineated on clear mylar overlays registered to each photograph. Each photograph was then viewed under magnification and a stereoscope so that subtle features could be discerned and mapped.
