Note I.- See Annex IS, Appendix 8, for graphical illustrations of obstacle data collection surfaces and criteria used to identfi
obstacles in the defined areas.
Note 2.- Implementation of Annex IS provision 10.6.1.2 concerning the availability, as of I8 November 2010, of obstacle data
according to Area 2 and Area 3 specifications would be facilitated by appropriate advanced planning for the collection andprocessing
of such data.
