Geospatial data for the Vegetation Mapping Inventory Project of Saint Croix National Scenic Riverway
2009. Geospatial data for the Vegetation Mapping Inventory Project of Saint Croix National Scenic Riverway
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 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 SACN vegetation map provides 32,751 polygons of detailed attribute data and covers 68,216.7 ha, with an average polygon size of 2.1 ha. Of the area mapped, 30,891 polygons (94.3%) represent natural/semi-natural types in the NVCS, encompassing 51,523.7 ha (75.5%) of the total map extent.
