... It was proposed, therefore, that a broad cross section of users and potential users be queried to obtain a representative response. A representative sample of each of the user communities was surveyed by means of a questionnaire mailed to a targeted list of over 1,000 individuals, supplemented by questionnaires published in sources that provided exposure to the largest marine audiences (e.g., nautical magazines and the U.S.

... In 1986 the International Maritime Organ~zation's Maritune Safety Committee agreed on the need to produce a standard that would ensure recognition of an electronic chart display and information system (ECDIS) as the "legal equivalent of a paper chart" within the meaning of the internationally mandated Safety of Life at Sea carriage requirement for nautical publications (Kite-Powell, 19921.

... Professional mariners generally wanted less cluttered charts, while recreational boaters wanted more supporting information. The respondents who were using electronic navigation systems seemed universally well satisfied with them and expressed the conviction that electronic navigation is the "wave of the future." WORKSHOP ON USER NEEDS The workshop i .ncluded representatives of all of the user communities identified for the questionnaire mailing.

... While having the most current chart is generally important to the recreational boater, chart update information is generally not a critical requirement. · Nonnavigational users use nautical charts as a geographic basis for analyzing and displaying other oceanographic, geophysical, or topographic information.

... Loran grids extending into harbors, waypoint definitions, bridge names and opening schedules, tidal ranges, bottom types, and chart symbol definitions would all be welcomed. · Military users' needs encompass both the needs of professional mariners and those of the emerging nonnavigation users:

... of the paper chart as a basis for commercial navigation in the near future" is the lack of availability of digital data sets issued on the authority of national hydrographic agencies. Although private firms have digitized selected features from many of the worId's charts for use in simple electronic charts on fishing vessels and recreational boats, these data sets cannot be used as the legal equivalent of paper charts by commercial vessels because they do not carry the legal certification of government hydrographers.

... Second, an expanding community of nontraditional users is creating a different set of needs for nautical data that can serve as the basis for analysis of various coastal and ocean processes and environmental parameters. The workshop discussions indicated that nautical information products must be tailored to meet the needs of individual users and that no single product line could meet the needs of all users.
