Prototype Global Shoreline Data (Satellite Derived High Water Line Data)
|
| The NGA Office of Global Navigation, Maritime Domain 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. Work to fill in gaps in the prototype Global Shoreline Data set, particularly cloud cover gaps, has now been completed. Continuous shoreline data, approximately between 60 degrees north and 56 degrees south, are being made available. These segments are being made available in the interest of supporting outside users who may have immediate application for these higher resolution data than World Vector Shoreline (WVS®).
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.
