Orthophotos, raw imagery, and scanned aerial photos are common files held here. Delineation of vegetation map classes was based on interpretation of digital aerial imagery utilizing additional digital and non-digital data sources. The primary imagery used as base layers for mapping were the digital orthophoto mosaics of leaf-off color infrared aerial photography flown for this project in March 2003 and leaf-on color infrared aerial photography flown for this project in October 2004. Additional digital aerial imagery sets which were used included leaf-off color infra-red digital orthophoto quarter quads flown in spring 1996 (USGS 1995) and true color leaf-off orthophoto quarter quads flown in spring 2003 (WVSAMB 2005). Transparencies of leaf-on color infrared aerial photography flown in October 2003 (Vanderhorst et al. 2007) and the original transparencies used to produce the orthophoto mosaics for this project were examined on a light table to help distinguish signatures which were not apparent on the digital imagery. Utilization of these multiple sets of aerial photography often helped to overcome deficiencies (e.g. shading) of the primary orthophoto mosaics. Ancillary GIS layers used to assist photointerpretation included digital rastor graphs of USGS topographic maps and the landform and Ecological Land Unit models developed for this project.

Color infrared, stereo pair, 1:12,000 scale, aerial photography of New River Gorge National River was acquired on March 27, 2003, during leaf-off conditions, by Sanborn Mapping Company, Inc. A digital orthophoto mosaic was produced from 471 color infrared aerial photographs, scanned at 600 dpi with 24-bit color depth. Scanned .tif images of the aerial photographs were imported into ERDAS IMAGINE IMG format where a photo block was created using the airborne GPS and IMU data that Sanborn Mapping Company, Inc. supplied with the aerial photography.

The primary imagery used for the base map for the project was 2016 60 cm National Aerial Imagery Program (NAIP) imagery. Additional imagery supporting the interpretation phase included current and historic true-color Google Earth and Bing Maps imagery, as well as 2015 4-band 30 cm imagery from Cornerstone Mapping Inc., and imagery from Digital Globe, Inc.

Sanborn Mapping Company, Inc. acquired color infrared, stereo pair, 1:12,000 scale aerial photography for a digital orthophoto mosaic of GARI on March 27, 2003, during leaf-off conditions. The aerial photographs were delivered to the NPS, quality checked, accepted as provided, and sent to NCSU. Upon receipt at NCSU, the aerial photographs were counted to make sure that none were missing, scanned and saved in TIFF format, and placed in the data archive that NCSU maintains for the NPS Northeast Region Inventory & Monitoring Program. Associated data and information provided by Sanborn Mapping Company, Inc. that are also stored in the data archive include the airborne global positioning system (GPS) and inertial mapping unit (IMU) data files, the camera calibration certificate, and a digital flight index map.

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. One complete set of aerial photography was provided for the project, including both a set of prints and diapositives. The specifications for the aerial photography are listed below: Color infrared photography (CIR) Flown October 29, 1996 - (height of the leaf change) Nominal scale - 1:6,000 (Nominal refers to the photo scale variability within each aerial photo and across flight lines. In this case the photo scale ranged from approximately 1:5,800 to 1:6,200) Approximate photo size - 9" x 9" Overlap between photos and across flight paths met the standards for photo interpretation using a mirror stereo scope. (Approximately 60% between photos and 10% - 20% between the flight lines)

Orthophotos, raw imagery, and scanned aerial photos are common files held here. The digital aerial imagery used for the onscreen mapping was obtained on September 24, 2012 (CIR imagery), and on October 12, 2012 (true-color imagery), using a plane-mounted digital camera. Many supplemental imagery and data sets were also used by the mappers to visualize and understand the landscape. These layers increased the mappers’ ability to understand historical landscape change and use, determine wet and dry areas, and better visualize conifers. The supplemental imagery and data sets included digital aerial imagery and field data from the field reconnaissance efforts, and vegetation plot and verification site data.
