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.

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. Spatial data from field observation points and quantitative plots were used to edit the formation-level maps of Richmond National Battlefield Park to better reflect vegetation classes. Using ArcView 3.3, polygon boundaries were revised onscreen over leaf-off photography. Units used to label polygons on the map (i.e. map classes) are equivalent to one or more vegetation classes from the regional vegetation classification, or to a land-use class from the Anderson Level II classification system. Each polygon on the Richmond National Battlefield Park map was assigned to one of twenty-one map classes based on plot data, field observations, aerial photography signatures, and topographic maps. The mapping boundary was based on park boundary data obtained from Richmond National Battlefield Park in June 2004.

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. A geodatabase containing various feature class layers and tables was constructed to show the locations of vegetation types and general land cover (vegetation map), vegetation plot samples, AA sites, project boundary extent, and aerial photographic centers. The feature class layer for the KEMO vegetation map provides 296 polygons of detailed attribute data covering 1419.2 hectares, with an average polygon size of 9.4 hectares. Of the area mapped, 195 polygons (65.9% of all polygons) represent natural/semi-natural vegetation types in the NVCS, encompassing 1,129.1.6 hectares (79.6%) of the total map extent.

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. 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.

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. The polygons on the plastic overlays were then corrected using photogrammetric procedures and converted to vector format for use in creating a geographic information system (GIS) database for each park. In addition, high resolution color orthophotographs were created from the original aerial photographs for use in the GIS. Upon completion of the GIS database (including vegetation, orthophotos and updated roads and hydrology layers), both hardcopy and softcopy maps were produced for delivery. Metadata for each database includes a description of the vegetation classification system used for each park, summary statistics and documentation of the sources, procedures and spatial accuracies of the data. At the time of this writing, an accuracy assessment of the vegetation mapping has not been performed for most of these parks. Thus, those procedures and results are not included in this report.
