* 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 multiply percent-area
and total acreages from the Inventoried Roadless Area coverage. Derived acres have been rounded to the
nearest 1,000 acres. |
