Current format is ArcGIS file geodatabase but older formats may exist as shapefiles. GIS Database 2011 - 2012: Pea Ridge National Military Park = 4,267 acres (1,727 hectares) Base Imagery used for mapping (acquired by MoRAP): 2009, Benton County, AR, leaf-on, true color, 0.61 m (2 feet) 2009, Benton County, AR, leaf-off, 4-band CIR, 1 m Minimum Mapping Unit = 0.5 hectares (ha) Minimum Patch Size = .005 hectares (ha) Total Size = 300 Polygons Average Polygon Size = 14.22 acres (5.75 ha) Overall Thematic Accuracy = 93.1% Project Completion Date: 11/2012

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 used for mapping (acquired by MoRAP): 2009, Benton County, AR, leaf-on, true color, 0.61 m (2 feet) 2009, Benton County, AR, leaf-off, 4-band CIR, 1 m The mapping component was produced by identifying land cover in a three-step process: (1) image objects were generated at 1 m resolution using e-Cognition applied to stacked leaf-on and leaf-off air photos, (2) image objects were coded with land cover classes on-screen, and (3) image objects were cut and corrected via heads-up digitizing at a display scale of 1:1,500 against a back-drop of air photos. The best available imagery was from the NAIP. This included 2009 leaf-on true color and 4-band color infrared (CIR) 1 m resolution photos, and 2007-2009 leaf-off true color 2 foot resolution photos.

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.

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.
