摘要

The rapidly increasing need for Electronic Navigational Charts (ENC) has led many Hydrographic Offices to a situation where there are two separate production lines - and two separate databases - for two products, ENC cells and printed charts. The existing modus operandi means that the same updates are done twice in two different databases. This paper starts with a description of the most challenging specific requirements of an application schema and production system supporting the production of ENC cells and printed charts from one common database. The paper outlines possibilities to expand the S-57 object catalogue by adding cartographic features and attributes which would enable presentation of the data according to the presentation requirements of printed charts. The paper then introduces the Finnish Maritime Admimistration's new chart production system, nSector, which uses these cartographic objects and attributes and increases remarkably the level of quality control during the production process. Advances in navigation technology have set new demands on accuracy, reliability and the form of nautical charts. The positional accuracy of the chart should meet the increased accuracy of the positioning systems. To fully benefit from the dynamics of the modern positioning methods, high quality digital chart products should also be available. This allows real-time tracking of a ship's own position on the electronic chart display and also the development of more and more advanced integrated navigation systems.
