Geospatial data for the Vegetation Mapping Inventory Project of Sagamore Hill National Historic Site
2007. Geospatial data for the Vegetation Mapping Inventory Project of Sagamore Hill National Historic Site
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 2006 revised preliminary map and the final 2007 post-AA maps were created following the USGS/NPS Vegetation Mapping Program protocols. Using ArcMap 9.2 (ESRI 1999–2006), polygon boundaries were revised on screen based on the plot data, field observations, classification analyses, aerial photography signatures, and topographic maps. Each polygon was assigned the USNVC Community Element Global (CEGL) code of a preliminary vegetation association based on the information sources listed above. Second, third, and fourth CEGL code choices were entered in cases of uncertainty, or for polygons representing mosaics of two or more types.
