Imagery data for the Vegetation Mapping Inventory Project of Fort Necessity National Battlefield

Metadata Updated: June 5, 2024

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.

Color infrared, stereo pair 1:6,000 scale aerial photography for a digital orthophoto mosaic of Fort Necessity National Battlefield was acquired from an overflight on April 13, 2003 (i.e., during leaf-off conditions) by Kucera International. The photography was delivered to the National Park Service (NPS), quality checked, accepted as provided, and sent to North Carolina State University (NCSU). Upon receipt at NCSU, the air photos were counted to make sure that none were missing, scanned, and placed in the air photo archive maintained at NCSU for the NPS Northeast Region Inventory & Monitoring Program. Associated data and information provided by Kucera, and also stored in the air photo archive, include the airborne GPS/IMU files, the camera calibration certificate for the camera, and the hardcopy flight report for the photography that crosswalks the airborne GPS/IMU data to the photo frame numbers. The mosaic was produced from 41 color infrared air photos scanned at 1200 dpi with 24-bit color depth. The scanned images of the air photos were imported into ERDAS Imagine (.img) format where a photo block was created using airborne GPS and IMU data that Kucera International supplied with the aerial photography. After receiving the digital orthophoto mosaic from North Carolina State University, ecologists at the Pennsylvania Natural Heritage Program developed a formation-level vegetation map. Aerial photointerpretation was informed by viewing the diapositives through a stereoscope, viewing the digital mosaic onscreen, and overlaying the formation-level polygons onto digital topographic quad maps.
