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. 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.

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. 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.

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.

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.

Kucera International, Inc., acquired color infrared, stereo pair 1:12,000 scale aerial photographs for a digital orthophoto mosaic of Upper Delaware Scenic and Recreational River on March 28 and 29, 2004, during leaf-off conditions. A total of 648 aerial photographs that cover the park, as well as a relatively large buffer area outside the park, were delivered to the National Park Service (NPS), quality checked, accepted as provided, and sent to North Carolina State University (NCSU).

During the planning and coordination phase, CTI staff reviewed all available existing digital imagery for its potential use as the base-map for the vegetation mapping at AMIS. The most promising and easy to access was the data catalog found on the Texas Natural Resource Information System (TNRIS) website. Navigating to the orthoimagery-statewide web page, the list of existing imagery covering AMIS included multiple products produced annually by the U.S. Department of Agriculture’s National Aerial Imagery Program (NAIP). The corresponding NAIP 2010 1-meter (pixel resolution) quarter-quad datasets for AMIS were downloaded and used during the preliminary planning and mapping stages. Since 2012, other orthoimagery covering AMIS was made available on TNRIS and was downloaded by CTI. These included the 2012 and 2016 versions of the NAIP 1-meter quarter quads and the 2015 Texas Orthoimagery Program (TOP) 50-cm quarter quads (Figure 13). All contained an infrared band and the NAIP 2016 product was determined useful for supplying the most up-to-date vegetation patterns (especially in the dynamic inundation zone and other recently disturbed sites) and as an ancillary dataset if needed for hard to view canyons and within shadows along the river bluffs. Overall the 2015 TOP product was found to be superior to the 2016 NAIP imagery due to its finer resolution and higher contrast. The 2015 TOP imagery was then selected and used as the primary basemap for the remainder of the mapping efforts.
