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. Base Imagery = BOR-supplied 2002, True-color, 3-band, 1-meter, 1:12,000-scale ortho-image, NAIP 2009, True-color, 3-band, 1-meter, 1:12,000-scale ortho-image All of the ground information obtained in 2007 was documented and summarized to apply to the NAIP ortho-imagery and the final list of NVC associations for LARO in 2008 and 2009. CTI created preliminary map classes based on the ORNHIC preliminary list of plant associations developed from previous projects and all developed areas, roads, streams, badlands exposures, and other obvious features were manually digitized and incorporated with the project boundary into a draft GIS layer.

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.

Orthophotos, raw imagery, and scanned aerial photos are common files held here. 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.

Orthophotos, raw imagery, and scanned aerial photos are common files held here. William Frament, USDA Forest Service (Northeastern Area State and Private Forestry, Durham, NH) acquired color infrared, stereo pair 1:8,000 scale aerial photography for digital orthorectified photomosaics of Gateway National Recreation Area on December 17, 2002, during leaf-off conditions. Hoffman and Swinburne islands of the Staten Island Unit were excluded from this air photo coverage, and thus excluded from the vegetation map. Frament scanned the aerial photographs at 600 dpi and delivered the scanned image files, in TIFF format, and the hard copy photographs to North Carolina State University (NCSU). The photographs, the camera calibration certificate, and a shapefile of photo centers provided by Frament are stored in the archive that NCSU maintains for the NPS Northeast Region Inventory & Monitoring Program.

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).
