THE INTERNATIONAL CONTEXT The International Hydrographic Organization and the International Maritime Organization play significant roles in regulating the use and production of nautical charts. The International Maritime Organization was created as a specialized agency of the United Nations in 1959 and has been the leading forum for international cooperation on issues of maritime trade, including safety standards, such as the international carriage requirement for nautical charts in the Safety of Life at Sea (SOLAS)

While practices and law regarding chart production and copyright vary considerably, in virtually all nations the development and management of a quality hydrographic data base and preparation of associated charts are accepted as a basic responsibility of the national government. From a regulatory viewpoint, international chart carriage requirements and government backing of charts are the primary forces driving the present nautical charting system.

In addition, the Coast and Geodetic Survey provides aeronautical charts and performs geodetic, hydrographic, and photogrammetric surveys and field investigations. It processes air and marine mapping and charting data obtained from various sources to produce approximately 1,000 nautical charts, nine volumes of Coast Pilot publications, approximately 600 bathymetric maps, and approximately 10,000 aeronautical charts.

As a result of the expanding needs for information for use in management as well as navigation, NOAA's nautical charting mission is evolving from that of producing a one-product finished paper chart series to that of creating and maintaining a digital data base from which many products, analyses, and services will flow to customers. The hnpact of Technology The rapid growth of computer technology over the past two decades has enabled a radical departure from the traditional paper chart the electronic chart, which is an electronic digital display of information (a navigation data base and input from a variety of sensors)

PROBLEMS AND CONSTRAINTS LIMITING CHANGE Limited Resources The resources available to NOAA's nautical charting programs over the past 5 years have decreased in constant dollars in relation to NOAA's overall budget (see Figures 1-2 and I-3) and are insufficient to meet the changing user demand for new products, to digitize existing nautical data, and at the same time, to adopt new technologies.
