Science, education, commerce, planning, and resource management have relied for centuries on the availability of accurate maps. In coastal regions, high-quality maps are essential for safe navigation, resolving jurisdictional boundaries, understanding processes, mitigating hazards, tracking environmental changes, establishing inventories of resources and habitats, and developing new programs and policies.

The committee was tasked to identify highpriority needs, evaluate the potential for meeting those needs based on the current level of effort, and suggest steps to increase collaboration and ensure that the nation's need for spatial information in the coastal zone is met in an efficient and timely manner. In order to understand the needs and activities of the very large and diverse community involved with spatial information in the coastal zone, the committee and staff sought information and perspectives from agencies and individuals involved in numerous aspects of coastal zone mapping.

Differences between agency missions, onshore topographic versus offshore bathymetric mapping techniques, differing vertical reference frames, and the inherent difficulty of collecting source data in the surf and intertidal zones have combined to produce this fundamental incompatibility. It will be nearly impossible to properly understand processes, undertake planning, and establish boundaries in the coastal zone while two sets of

Recommendation 1: In order to combine onshore and offshore data in a seamless geodetic framework, a national project to apply Vdatum tools should be initiated. This will involve the collection of real-time tide data and the development of more sophisticated hydrodynamic models for the entire U.S.

With a seamless bathymetric/topographic dataset across the land-water interface, appropriate difference or tidal models, and consistent horizontal and vertical reference frames, any shoreline definition can be transformed and integrated within the common framework. The Vdatum tool kit and associated Web sites will be the key to establishing internally consistent shorelines between and among disparate surveys and studies.

Coordination of such a site logically falls under the purview of the FGDC and is fully consistent with the Geospatial One-Stop concept. DATA INTEGRATION, INTERCHANGEABILITY, AND ACCURACY Providing easy access to data through a single Web portal is a critical starting point for addressing the needs of the coastal zone community.

Recommendation 7: All federally funded coastal zone mapping and charting activities should be registered at a common, publicly avail able Web site. This combined registry should be accessible through the single Web portal for coastal zone information.

. A less appealing alternative might be either a new government office or an extragovernmental body charged with establishing oversight of all national coastal mapping and charting activities.

Given the number of agencies and private-sector companies involved in coastal mapping and their disparate missions and budget directives, it is unrealistic to expect agreement on one unified and prioritized national mapping initiative. While each agency has responsibility for its own mapping priorities, a strong and enforceable mechanism for tracking and coordinating existing, ongoing, and planned mapping efforts (Recommendation 7)

The recommendations and strategies outlined above call for the establishment of a consistent geospatial framework and the application of innovative new acquisition, integration, and data management technologies that should allow coastal zone scientists, engineers, and managers to efficiently produce easily accessible, fully interchangeable, accurate, timely, and useful geospatial data and mapping products that seamlessly extend across the coastal zone. The recommendations also suggest simple mechanisms to enhance collaboration and cooperation among those charged with acquiring data in this complex region.
