Prototype Global Shoreline Data (Satellite Derived High Water Line Data)
|
| The NGA Office of Global Navigation, Maritime Division is in the process of developing a new version of World Vector Shoreline (WVS®) and in support of this effort has acquired a prototype Global Shoreline Data set. This new shoreline is an approximation of the High Water Line; it is NOT a Mean High Water Line since the source data have not been tide coordinated. Regions 2, 3, and part of 10 have been updated with post December 2004 imagery. Plans are in work to fill cloud gaps. As segments of the prototype version are gap filled, they will replace the original shoreline segments. These segments are being made available in the interest of supporting outside users who may have immediate application for these higher resolution data.
IMPORTANT: These prototype data are not currently intended for safety of navigation products and do not necessarily reflect recognition of the political status of an area by the coastal nations affected or by the United States Government. (Region 29 shoreline is not available.)

Digital Nautical Chart (DNC®)
|
| The Digital Nautical Chart® is produced by the National Geospatial-Intelligence Agency (NGA) and is an unclassified, vector-based digital database containing maritime significant features essential for safe marine navigation. DNC’s 018, 026, 027, and 028 are produced in partnership with Canadian Forces Mapping and Charting Establishment Hydrographic Services Office (Esquimalt). Initial data collection of the database is from a portfolio of approximately 5,000 nautical charts that will ultimately provide global marine navigation between 84° North latitude and 81° South latitude and supports a variety of Geographic Information System applications.

Vector Product Format Database Update (VDU)
|
| NGA's VPF Database Update (VDU) software was designed to meet digital correction and update requirements of VPF data products resident at remote user sites. The U.S. Navy and NGA believe that "commercial patch" technology has matured significantly in the past several years, to the point where it is now a viable solution to VDU requirements. Although there is a need for future rapid update of all VPF data, the immediate need for this capability is to support the Digital Nautical Chart (DNC®) program. DNC® update requirements are unique due to the frequency, volume and criticality of update information to support safe electronic navigation. (Updated 19 November 2009) |
