Orthophotos, raw imagery, and scanned aerial photos are common files held here. Photo Date: 10/24/2000, Scale: 1:12,000 Area(ac): 3955 The CIR aerial photographs in transparency format were scanned at 600 dpi (42 μm) using an Epson Expression 10000XL flatbed scanner. This scanner is capable of scanning materials up to 11x17‖ in size at optical resolutions up to 1200 dpi and is equipped with a backlight attachment for scanning transparent materials. The 600 dpi scanning resolution was selected to balance the resolution requirements for the orthophotos with data storage and processing considerations. The photographs were laid on the scanning surface and, to reduce distortions, a heavy piece of clear glass was placed on top to ensure flatness of the film during scanning. Each photo was then scanned using Adobe Photoshop and saved as a 24-bit color TIFF file. During scanning, care was taken to scan the full frame of the photograph, including the corner fiducial marks and marginal data. File names for the scanned photographs were assigned according to the flight line and frame number. For example, photo 13 from flight line 2 was named 2-13.tif. Photos from each park were stored in separate folders on the CRMS Data server. All photos from each flight line were scanned. For original photos of 1:12,000 and 1:16,000 scales, the resulting pixel sizes were approximately 0.5 m and 0.67 m, respectively. After the photos were scanned, the original film transparencies were turned over to the photointerpreters while the photogrammetric operations continued using the digital data.

Orthophotos, raw imagery, and scanned aerial photos are common files held here. The Southeast Coast Network contracted with Aero-Metric, Inc., through the USGS Rolla, Missouri office to provide color-infrared (CIR) aerial photographs. Airborne GPS data and CIR images were provided by Richard Crouse & Associates, Inc. These images were scanned by HAS Images, Inc. Ground check point data was provided by Aero-Metric, Inc. The project was referenced horizontally to the North American Datum of 1983 (NAD83), Universal Transverse Mercator Zone 16, and vertically to the North American Vertical Datum of 1988 (NAVD88). Features were interpreted using 1:12,000 scale digital color-infrared aerial photography (flown 31 May 2009) through heads-up-digitizing in ArcGIS (Version 10.0, © 2010 Environmental Systems Research Institute, Redlands, California). Polygons were mapped to a 0.5-hectare minimum mapping unit (MMU).

Imagery Date: 10/25/2001, Scale: 1:12,000, Area 3,960 ac Overstory vegetation was interpreted from the 1:12,000 to 1:16,000 scale leaf-on color infrared aerial photographs in 9 x 9 inch film transparency format. A compilation of all field information was used by CRMS photointerpreters to connect the NVCS association-level classes identified in the field with photo signatures for vegetation patches identified on the color infrared aerial photographs. The locations of CRMS field points were transferred from the GPS units to ArcMap and superimposed on orthorectified images of each park.

Orthophotos, raw imagery, and scanned aerial photos are common files held here. We supplied the University of Georgia team with all plot data already collected and a dichotomous key to the communities of the park and we walked throughout the park to help them identify unique mapping units. Since photointerpreters rely heavily on canopy species composition, understory species composition, and disturbance to classify polygons and ecologists rely just as heavily on the shrub and herb layer to classify types, the mapping units and the vegetation classification units do not always “crosswalk” (match up) perfectly. The last step of the project (not detailed in this report) will be to work reconcile mapping units with vegetation associations to produce mapping units that match up well with the ecological units of the National Vegetation Classification.

The files linked to this reference are the geospatial data created as part of the completion of the baseline vegetation inventory project for the NPS park unit. Current format is ArcGIS file geodatabase but older formats may exist as shapefiles. Large scale final map products were created within ArcMap and designed to show both the orthophoto coverage and the vegetation maps. For the vegetation maps, colors were assigned and the polygons labeled with the dominant vegetation and modifier and, where present, the second vegetation and modifier. For the orthophoto maps, the photos were simply plotted at the same scale and area coverage as the vegetation maps. Additional planimetric map data included roads, trails, hydrology, boundaries and a UTM coordinate grid. Legends are designed to provide full definitions of the vegetation and buffer classes and modifiers, as well as information about the park, map projection, data sources and authorship (Figure 19). All maps are projected to the Universal Transverse Mercator Coordinate System, North American Datum of 1984, in the local zone for the specific park.
