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. Natural color imagery was acquired for FOBU on July 21, 2004 and processed into 1:12,000-scale hardcopy prints. The 9-x 9-inch photographs were sent to the USGS, scanned at 1000 dots per inch, and mosaicked into a seamless one-meter digital image orthorectified using a 10 m digital elevation model. NAIP imagery was also obtained as an ancillary dataset for the project area. This imagery was one-meter color-infrared data flown during 2006.

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. 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.

Orthophotos, raw imagery, and scanned aerial photos are common files held here. Since JODA represented a small site, existing sources of imagery were evaluated and the National Aerial Imagery Program (NAIP) products were found to be adequate. Based on the currentness of the 2009 product, this true-color, 1-meter pixel was accepted as the base imagery. The 2005 true-color, 1-meter pixel product was also used as ancillary data.

Orthophotos, raw imagery, and scanned aerial photos are common files held here. The mapping component was produced by identifying land cover on air photos and hand digitizing on-screen. Heads-up digitizing was accomplished at a display scale of not more than 1:1,000 against a back-drop of air photos. Imagery was the most recent available from the National Agriculture Imagery Program. This included 2010 leaf-on true color and 2006 leaf-on color infrared images. The historic black and white photos from 1938 and 1968 showed the location of former croplands that have since been restored to tallgrass prairie, plus the location of former roads that have been removed and restored to native grasses. Former roads were avoided as potential sample plot locations.

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).

Orthophotos, raw imagery, and scanned aerial photos are common files held here. Color infrared (CIR) aerial photographs of the park at 1:12,000 scale were acquired by Aero-Metric, Inc. on May 11, 2011. These photos were scanned and converted to digital orthophotographs at 0.3-meter (1ft) resolution before they were delivered to the National Park Service. Digital orthophotographs and hardcopy photographs in both film transparency and paper print formats were provided to the University of Georgia Center for Geospatial Research. Six photos in two flight lines were required to cover Fort Caroline National Memorial.
