Geospatial data for the Vegetation Mapping Inventory Project of Gulf Islands National Seashore
Description
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.
The project geodatabase links the spatial vegetation data layer to vegetation classification, plot photos, project boundary extent, AA points, and the PLOTS database. The geodatabase includes USNVC hierarchy tables allowing for spatial queries of data associated with a vegetation polygon or sample point. All geospatial products are projected using North American Datum 1983 (NAD83) in Universal Transverse Mercator (UTM) Zone 16 N. The final GUIS vegetation map consists of 1,268 polygons totaling 35,769.0 ha (88,387.2 ac). Mean polygon size is 28.2 ha (69.7 ac). Mean polygon size, excluding water, is 3.6 ha (8.9 ac).
