National Park Service GIS Technical Support Center
This project involves developing protocols for GIS application to National Park management problems. We construct solutions, train personnel, manage data, and assist with overall GIS planning for both individual parks and for the NPS as a whole. The Nature Conservancy and a network of Natural Heritage Programs are developing a hierarchical vegetation classification system. NC State provided the first attempt at implementing a subset of this system. Shiloh National Military Park was one of the National Park Service units selected for application of the classification system.
PETERSBURG HAY
Petersburg National Battlefield resource management maintains a population of horses at the park. Due to the increasing cost of hay needed to feed the horses, creative ideas were discussed. Among them were producing hay on park property. North Carolina State, a designated National Park Service GIS Regional Technical Support Center, used USGS digital orthophoto quarter quadrangles as a backdrop to digitize hay fields. The hay fields were then overlaid with a soils coverage digitized from the county soil survey. The resultant coverage produced the information needed to estimate hay in tons/acre/year.
VALLEY FORGE VEGETATION
Valley Forge National Historical Park is beginning a vegetation mapping program in coordination with North Carolina State University (NCSU) and The Nature Conservancy. Using softcopy photogrammerty, the National Park Service GIS Regional Technical Support Center at NCSU will create a vegetation cover type coverage based on 1:6000 CIR aerial photography acquired during September 1999. NCSU will also produce a seamless digital mosaic of the aerial photography to allow users to visualize current conditions at the park and the distribution of different cover types.
GETTYSBURG MONUMENTS
Gettysburg National Military Park, the site of the largest Civil War battle ever waged in the Western Hemisphere, is the home of several hundred monuments dedicated to the units and soldiers of the Civil War. In an effort to map all the monuments, the National Park Service GIS Regional Technical Support Center at North Carolina State University used global positioning system technology along with traditional aerial photography to map the location of approximately 400 monuments. This information allows the park to plan around the monuments and ensure their story is preserved.
CAPE HATTERAS FUELS
Cape Hatteras National Seashore spans over 70 miles along the coast of North Carolina. Using aerial photography, the National Park Service GIS Regional Technical Support Center at North Carolina State University developed a vegetation cover type data layer for inclusion into the Cape Hatteras NS GIS. The accuracy assessment of the data was based on two strata, interior points and boundary points. A boundary point was defined as one within 75 feet of a vegetation cover type boundary line on the aerial photo. An overall accuracy of 70% was obtained. The same vegetation data was used to derive a fire fuel model data layer for use in resource management.
