Errors in the source geospational data; < # 2. Cases involving irregularly shaped boundaries, such as those formed < # by rivers and roads, etc.; or < # 3. Errors in the methods or programs that are used to compute the < # approximations. < # < # Airspace information for special use airspace, including Prohibited, Restricted,< # Alert, Military Operation, and National Defense areas are taken from AIXM < # files published via the Facility Aeronatical Data Distribition Service of the< # National Flight Data Center. < # < # Note that the software used to produce the approximations contained herein < # has not been certified for navigational use -- CONSEQUENTLY, THIS < # INFORMATION SHOULD NOT BE RELIED UPON FOR NAVIGATION.
