* These GIS overlays were prepared from coverages compiled at various scales and resolutions.  To account for the differences in scales and resolutions, a percent-area by attribute was calculated for each characteristic overlay layer.  The acres in each roadless category/characteristic attribute were calculated by multiplying percent-area and total acreages from the Inventoried Roadless Area coverage.  Derived acres have been rounded to the nearest 1,000 acres.
