A data processing task was needed by National Park Service to transpose field tabular and spatial data into various digital formats of the 1994 Aquatic Plant Survey Report. A survey of aquatic vascular plants was conducted in a 122 mile stretch of the Upper Delaware River between Hancock, New York and the Delaware Water Gap in 1991 and 1992. A total of 196 sites were inventoried and twenty-eight species of plants were recorded. The aquatic vascular plant flora in this section of the Delaware River appeared to be thriving, due in large part to good water quality and moderate impacts by man. The purpose of this task was the digitizing of hand-drawn field mapping data from hardcopy paper maps into digital map products. These digital mapping files are in the NPS standard GIS format and in National Park Service's accepted coordinate and projection systems. This is a data set composed of field survey of aquatic vegetation in the Delaware Water Gap and the Upper Delaware Scenic and Recreational Area National Parks. Data were compiled by field sampling with GPS coordinates and underwater imaging and bathymetry. Data were compiled by teams composed of personnel from the National Park Service, the U.S. Geological Survey and the Western Pennsylvania Conservancy. The data were used as training and ground truth for remote sensing image analysis of hyperspectral collected by the Civil Air Patrol with the Airborne Real-time Cueing Hyperspectral Enhanced Reconnaissance, also known by the acronym ARCHER. Archer is an aerial imaging system that produces ground images far more detailed than plain sight or ordinary aerial photography can. It is the most sophisticated unclassified hyperspectral imaging system available, according to U.S. Government officials. ARCHER can automatically scan detailed imaging for a given signature of the object being sought (such as a missing aircraft), for abnormalities in the surrounding area, or for changes from previously recorded spectral signatures. ARCHER was used in this project, to evaluate its potential for mapping submerged aquatic vegetation.
