Carl Sandburg Home National Historic Site

The CRMS, NPS and NatureServe worked to develop a geographic database of forest communities for several national parks in the Southeast, including the Carl Sandburg Home National Historic Site (CARL).  The polygons delineating vegetation communities are manually interpreted from 1:12,000 scale color-infrared aerial photographs in conjunction with inventory analyses from NatureServe field plots within the Park.  Polygons are then converted to a GIS database using ESRI ArcView and ArcGIS.  The final map products consist of a registered color infrared orthophoto and vegetation map.

Vegetation community classes were developed in cooperation with NatureServe.

The three dimensional model was generated from ortho-rectified imagery draped 
over a USGS digital elevation model and park building polygons extruded from it's surface.
