Imagery data for the Vegetation Mapping Inventory Project of Great Smoky Mountains National Park
2008. Imagery data for the Vegetation Mapping Inventory Project of Great Smoky Mountains National Park
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. Overstory vegetation was mapped using more than 1000 color infrared aerial photographs of 1:12,000 scale in film transparency format recorded with a Wild RC20 photogrammetric camera, f = 15 cm) in late October by the U. S. Forest Service. The fall photos were acquired when the leaves were still on the trees (leaf-on) and displayed a color diversity that allowed the vegetation communities/species to be identified. Relief displacements were a major problem, in some cases reaching more than 40 mm on the 23 x 23 cm format photographs. The understory vegetation was mapped from 1:40,000-scale color infrared photographs recorded (with a Wild RC30 camera, f = 15 cm) in the winter months as part of the USGS National Aerial Photography Program (NAPP).
