Vector Data

Abstract
Ships routeing systems and traffic separation schemes that have been approved by International Maritime Organization (IMO).
An Area to be Avoided (ATBA) is an area within defined limits that should be avoided by all ships or certain classes of ships, in which navigation is Particularly hazardous or in which it is exceptionally important to avoid casualties.
In general, ATBAs should be established only in places where:
inadequate survey or insufficient provision of aids to navigation may lead to danger of stranding; where local knowledge is considered essential for safe passage; where there is the possibility that unacceptable damage to the environment could result from a casualty; or where there might be hazard to a vital aid to navigation.
