Field data for the Vegetation Mapping Inventory Project of Palo Alto Battlefield National Historical Park

This reference is an assemblage of field data collected as part the baseline vegetation inventory for the park unit. Typical files here are vegetation plot data, accuracy assessment data, field photos, PDF showing locations of vegetation plots and accuracy assessment data, and other data for this type. We collected 46 field sites throughout the PAAL by recording vegetation occurrences and coverages, and documenting these occurrences with 35-mm slide photography. All field site data were assigned to a physiognomic level (class, subclass, group, subgroup, formation) and a floristic level (alliance, association) as required by the NVCS convention. An additional 92 field site locations were added in our second field trip from 15 to 19 March 2001, resulting in a total of 138 field sites distributed throughout the PAAL. Field site locations and descriptive data including 35-mm photography were entered into a geographic information system (GIS). The GIS included a visual portrayal of field site and GCP locations that were hotlinked to map identifiers overlain on 1999 mosaic photography coverage (Fig. 10). Clicking on a map identifier retrieved a tabular and visual display of all data and photography available for each field site and GCP location. The GIS project that contained GCP locations and descriptions (some with photography), field site locations and descriptions including photography was delivered to the PAAL personnel on October 11, 2000.
