This is a Vector data set. It contains the following vector data types (SDTS terminology):
Horizontal positions are specified in geographic coordinates, that is, latitude and longitude. Latitudes are given to the nearest 0.002. Longitudes are given to the nearest 0.002. Latitude and longitude values are specified in Decimal Degrees.

Polygon files from the three states were converted to raster grids with 200-meter cell sizes. The individual grids were merged, then smoothed with a majorityfilter function, then converted back to vector polygon format. The most generalized attributes from the three states were used to ensure uniformity within the regional view.
