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 (10.6.x) file geodatabase. To map the vegetation and land cover of the parks within the National Capital Region, the region initiated collective mapping efforts at 10 parks (NPS unit codes: ANTI, CATO, CHOH, GWMP, HAFE, MANA, MONO, NACE, PRWI, WOTR). NatureServe assisted with field plots, accuracy assessment, and building the vegetation classification for the vegetation map. This geospatial dataset only covers Monocacy National Battlefield.

Current format is ArcGIS file geodatabase but older formats may exist as shapefiles. To produce the digital map, a combination of 1:12,000-scale true color digital ortho-imagery acquired in 2003, 1:12,000-scale true color ortho-rectified imagery acquired in 2005, and all of the GPS referenced ground data were used. All of the interpreted and remotely sensed data were converted to Geographic Information System (GIS) databases using ArcGIS© software. All of the resulting map unit names, map unit codes, NVC information, and other relevant attributes were added to each polygon in the GIS layer.

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 Petersburg National Battlefield 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 (Anderson et al. 1976) Level II classification system. Each polygon on the Petersburg National Battlefield map was assigned to one of twenty 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 Petersburg National Battlefield in May 2006. Spatial data depicting the locations of earthworks was obtained from the park and used to identify polygons of the cultural map classes Open Earthworks and Forested Earthworks. One map class used to attribute polygons combines two similar associations that, in some circumstances, are difficult to distinguish in the field. The vegetation map was clipped at the park boundary because areas outside the park were not surveyed or included in the accuracy assessment. Twenty map classes were used in the vegetation map for Petersburg National Battlefield. Map classes are equivalent to one or more vegetation classes from the regional vegetation classification, or to a land-use class from the Anderson (Anderson et al. 1976) Level II classification system.

Current format is ArcGIS file geodatabase but older formats may exist as shapefiles. In 2003, we returned to Stones River National Battlefield to follow-up on the first three goals and to cooperate with the University of Georgia Center for Remote Sensing and Mapping Science on their project to map all vegetation communities in the park. We supplied Phyllis Jackson from the University of Georgia with plot data and a dichotomous key to the National Vegetation Classification (NVC) associations of the park and we walked throughout the park to help identify mapping units. Since photointerpreters rely heavily on canopy species composition, understory species composition, and disturbance to classify polygons and ecologists also rely on the shrub and herb layer to classify types, the mapping units and the vegetation classification units do not always crosswalk or match up perfectly. The last step of the project was to reconcile mapping units with vegetation associations to produce mapping units that match up well with the ecological units of the National Vegetation Classification (NVC). We continue to work with Phyllis Jackson of the University of Georgia on the mapping; the vegetation map will be produced separately by the Center for Remote Sensing and Mapping Science and will include any crosswalk as specified in the cooperative agreement.

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. Collectively, the MOCR spatial database layer is composed of 83 polygons covering 173.0 acres, with an average polygon size of 5.4 acres. Map classes representing natural/semi-natural types in the NVCS apply to 49 polygons (59.0% of all polygons) covering 128.7 acres (74.4 % of entire area) with an average polygon size of 2.4 acres. Of these natural/semi-natural types, the Early to Mid-Successional Loblolly Pine Forest dominates, both in frequency of polygons (22), and in size (57.6 acres). A close second, in terms of size, is the Atlantic Coastal Plain Bald-cypress-Blackgum Swamp which covers 40.6 acres. The Early to Mid-Successional Loblolly Pine Forest dominates drier upland sites on the eastern section of the park; whereas, the Atlantic Coastal Plain Bald-cypress-Blackgum Swamp is commonly found along the floodplain of Moores Creek.

The GIS included a visual portrayal of field site and GCP locations that were hotlinked to map identifiers overlain on 1999 mosaic photography coverage. 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.
