This dataset consists of a map depicting the distribution of cedar along the Natchez Trace Parkway. Ground-based vegetation classification was provided by the National Park Service and mapped by the U.S. Geological Survey, National Wetlands Research Center. In the final version of "Mapping the Natchez Trace Parkway," the Cedar class was merged with the Pine class (the alliance most frequently mistaken for cedar).
This dataset consists of a map depicting aquatic vegetation along the Natchez Trace Parkway. Four herbaceous aquatic alliances were manually mapped and aggregated as an aquatic vegetation class. Ground-based vegetation classification was provided by the National Park Service and mapped by the U.S. Geological Survey, National Wetlands Research Center.
This dataset consists of linear features depicting the main road running through the Natchez Trace Parkway and other roads visible on the color infrared photography. The Parkway is a 715-km roadway that historically connected the southern portions of the Mississippi River to the salt licks in central Tennessee. The vector data represent the roadway of the Parkway at an approximate along-track (parallel and perpendicular to the road) with a spatial accuracy of about 3 meters or less.
This dataset consists of a map depicting the distribution of sweetgum-oak mixed forests along the Natchez Trace Parkway. Ground-based vegetation classification was provided by the National Park Service and mapped by the U.S. Geological Survey, National Wetlands Research Center. In the final version of "Mapping the Natchez Trace Parkway," the Sweetgum-Oak class was merged with the Sweetgum class because most of the time it co-occurred with the Sweetgum field sites.
This dataset defines the symbology for the landcover map of the Natchez Trace Parkway. The map shows the distribution of 18 landcover classes based on the National Vegetation Classification Standard. Ground-based vegetation classification was provided by National Park Service (NPS). The mapping output and layer delineate grasses, road-developed areas, scrub-shrub, shrubland, plantation, water bodies, areas of white oak, oak, pine-oak, pine-cedar, pine-sweetgum, sweetgum (including sweetgum-oak), scattered trees, swamp forest, irregular classes, aquatic vegetation, invasive species, canopy gaps, and clouds. Mapped classes that have been digitized are noted with an asterisk (*) in the legend.
This dataset consists of a map depicting suspected sites of invasive species along the Natchez Trace Parkway. Four invasive species were manually mapped and aggregated as an invasive species class. Ground-based vegetation classification was provided by the National Park Service and mapped by the U.S. Geological Survey, National Wetlands Research Center.
This dataset consists of a map depicting the distribution of irregular classes along the Natchez Trace Parkway. Irregular classes are those forest alliances that were usually represented by one or two field sites. In addition, these alliances did not align with any of the major forest classes and for the most part did not contain species that were common to other alliances. Ground-based vegetation classification was provided by the National Park Service and mapped by the U.S. Geological Survey, National Wetlands Research Center.
This dataset consists of a map depicting the landcover of the Natchez Trace Parkway. The mapping output was created using mosaiced color infrared aerial photography of the Parkway. The map shows the distribution of 18 landcover classes based on the National Vegetation Classification Standard. Ground-based vegetation classification was provided by the National Park Service (NPS). The mapping output delineates grasses, road-developed areas, scrub-shrub, shrubland, plantation, water bodies, areas of white oak, oak, pine-oak, pine-cedar, pine-sweetgum, sweetgum (including sweetgum-oak), scattered trees, swamp forest, irregular classes, aquatic vegetation, invasive species, canopy gaps, and clouds.Total mapped area includes...
This dataset consists of a map depicting the distribution of undefined vegetation along the Natchez Trace Parkway. This vegetation could not be identified because there were no field site classification points provided by the National Park Service for this category of trees. However, there were more than 400 examples of this unique spectrally distinct vegetation pattern in mosaic 4 north of the Parkway. Researchers labeled these polygons as scattered trees in the final map output.
