Description: This is a vector polygon file showing the historic range forest types at Great Smoky Mountains National Park. The data was collected from a historic map drawn by Frank Miller, Assistant Forester, in 1938. The map was scanned using a Vidar color scanner and the digital images were brought into ArcMap. The map was originally divided into 4 seperate panels, thus there were 4 seperate image files. Each image was Georectified, Clipped and then the Mosaic tool was employed to create one large map image. Two feature classes, one a point feature class and the other a polyline feature class, were then created. The polyline class was used to digitize the boundary of each area of vegetation and a point containing the attributes of each area was placed within. After digitizing, the polyline layer was converted to a polygon feature class and the attribute table from the point layer was joined to the corresponding polygon within the feature class.
