Creating a GIS for Ocean Planning and Governance
Defining Issue: GIS has traditionally been used for terrestrial applications. Some data sets are problematic when working in the ocean. Sorting through the available shorelines to find the "official" shoreline is an issue. Finding and combining multiple resolution survey data from various sources to create reliable bathymetric data usable on the PC is also a challenge. There is also the issue of resolving the vertical datum when combining bathymetric and elevation data. GIS Solution: NOAA is working to create PC-based data sets and tools in ArcView that can be used for the ocean governance and planning community. Methodology: Key data sets for ocean planning are being created for the southeastern United States. A high-resolution shoreline will be created for this area by vectorizing the scanned by-products of the original tide-controlled photography used for NOAA nautical charting. Bathymetric survey data from NOAA and the Corps of Engineers will be combined with ship-tract soundings from various
sources to create bathymetric contours from the shoreline out to the Exclusive Economic Zone (EEZ), or 200-mile international boundary. These key data sets will be combined with other cadastral and natural resources data layers to create a GIS suitable for the ocean planning and governance community. Software: Esri's ArcInfo will be used for data development with ArcView Version 3.0 as the final software that will serve the ocean planning community.
