The nautical charting world reflects these changes in a growing demand for digital data sets to support electronic charts and other uses of marine geographic information in new, automated nautical chart production systems. As such, the nautical charting effort is part of a broader National Spatial Data Infrastructure (see NRC, 19931.

Surveys of users conducted in conjunction with the earlier NRC report (NRC, 1994a) and a recent series of regional workshops conducted by NOAA indicate that some segments of the marine navigation market will adopt this new technology rapidly, but many mariners, including a substantial portion of the recreational boating population, will have neither the ability nor the interest to use ECDIS, although there is a market in this community for other electronic chart products.

Non-navigation users are generally interested in supplemental digital data that provide information specific to coastal resource management. Data coverage includes shoreline physiography, salinity, turbidity, environmental geology, and "ridded bathymetric data models to support water circulation studies and storm surge predictions, as well as other variables of interest.

These data sets include selected, essential data such as fixed and floating aids, channel limits, highly selective depth information, shoreline, etc. Raster combined with ECDIS.

Although the primary role of NOAA's nautical charting mission is to help assure safety of navigation and support a wide range of maritime enterprises such as commercial transport, naval operations, fishing, and recreational boating, nautical information is of increasing importance to coastal land development, research, conservation, and coastal zone planning. To meet this broad and growing array of user needs, a previous NRC committee recommended that NOAA set its first priority in nautical charting on the development and maintenance of a digital nautical information database (NRC, 1994a)

Chart and Data Production NOAA should be commended for its successful development and quick deployment of the Super Computer-Assisted Revision System and the ComputerAssisted Compilation tool sets that significantly increase the revision rate of paper charts. However, a more comprehensive longer-term solution is needed to support the production of both paper charts and digital data.

to document their procedures and submit to audits by independent registrars. In addition, because of government control over electronic chart presentation, issues of sovereign immunity and product liability remain open to debate.
