Chart management system.

Abstract

The management of nautical charts are indispensable and essential work to hydrographic services. In order to carry out such work efficiently, a management system using an electronic computer has been developed by preparing data base of such information as the numbers and coverage of the charts listed in the Catalogue of Charts as well as their quantities in stock. It can be expected that this system will be effectual in managing, collecting, and retrieving data and information on charts and other hydrographic information, and this will be used as a fundamental chart data base system including such charted information as soundings, coastlines, etc.
