# > The information in this file is composed of computed approximations of the  <
# > arcs and lines that make up various airspace boundaries, which have been    <
# > derived from lists of points along those boundaries.  The point data has    <
# > been taken from the Federal Aviation Administration National Airspace       <
# > System Resource (NASR) files as published by the National Flight Data       <
# > Center.  Errors in the computed positions of the boundaries themselves will <
# > generally be less than 300 feet (although errors in the estimated positions <
# > of arc center points and radii will be much larger); however, any of the    <
# > following factors may cause errors to be many times greater:                <
