ECDIS will prove invaluable in keeping the shipping lanes open, pointing out that when visibility is traditionally poor around the

Great Lakes during the autumn, an ECDIS system can be used to successfully navigate through the bad weather and through the locks.

One test data set has been pro- vided to the Lake Carriers

For a system to have the designation of ECDIS, it must fulfill all of the require- ments laid down by the IMO's "IMO Performance Standards for

ECDIS."

To date, the Electronic Chart

Display and Information System (ECDIS) is the only type of elec- tronic charting system approved by the International Maritime

Organization (IMO) for the replacement of paper charts, which is an important disctinction. (Final approval is due in the spring by IMO and IHO of S57, version 3.0; equipment type approvals are expected in the fall). (Continued on page 62)
