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. Two sets of digital orthophotography were used in the vegetation/land use mapping process after the 2003 field season: (1) a digital orthophoto mosaic that is referred to as the Battlefield Unit photomosaic and (2) digital orthophotography of the Schuyler House, Saratoga Monument, and Victory Woods areas, located approximately seven mi (11.3 km) north of the Battlefield Unit, referred to as the Old Saratoga Unit orthophotography.

Orthophotos, raw imagery, and scanned aerial photos are common files held here. The initial base map layers were developed using the 2 m resolution color aerial orthophotos, since they had the highest spatial resolution. The regions were designed on their shared physiography: Eastside, Westside, Riverside, USFS, and Tsankawi sub-units. The vegetation map was developed using a combination of automated digital processing (supervised classifications and image segmentation) and direct image interpretation of high-resolution color and color infrared aerial orthophotography in combination with satellite imagery (Landsat Thematic Mapper).

NISI Photo dates: 10/24/2000, Scale: 1:12000, size: 948ac The CIR aerial photographs in transparency format were scanned at 600 dpi (42 μm) using an Epson Expression 10000XL flatbed scanner.

Orthophotos, raw imagery, and scanned aerial photos are common files held here. A set of CIR aerial photographs was collected on October 4, 2006. This photo mission was funded by the NPS VIP, and supervised by GLKN staff. This set of photography covered the entire GRPO vegetation mapping project extent at 1:12,000-scale and was the primary imagery used in photointerpretative mapping. In support of mapping from the CIR photos, we used a set of TC aerial photographs (1:8,000-scale) that was collected May 2, 2003, providing deciduous leaf-off viewing of the entire extent. This photo mission was funded by GRPO and supervised by GLKN staff. Having the TC photos gave interpreters a definite advantage in determining evergreen tree and shrub components within forest communities otherwise obscured by deciduous tree canopy on the fall-season CIR photos, thus giving credence to Avery’s statement regarding lack of a single all-purpose film emulsion. To assure stereo viewing and full aerial coverage, aerial photo missions were planned with a 60% forward-lap and 30% side-lap. Contact prints of both CIR and TC photo sets were produced for fieldwork use by mappers and vegetation crews. Diapositives of the CIR photo set were produced for photointerpretative mapping.

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.
