The raster file also contains data that is Geo-referencing; enabling computer based navigation attached to a GPS to locate and display the chart. The charts are stored in BSB format. "[The BSB file format] is a proprietary format of BSB Electronic Charts, LLP (bought by MapTech, Inc.)."
An Electronic Navigational Chart (ENC) is a digital representation of a real-world geographical area for the purpose of Marine navigation.Real-world objects and areas of navigational significance, or to a lesser degree - informational significance, are portrayed through Raster facsimiles of traditional paper charts; or more commonly through vector images, which are able to scale their relative ...
Nautical charts are essential tools for marine navigation; many countries require vessels, especially commercial ships, to carry them. Nautical charting may take the form of charts printed on paper (raster navigational charts) or computerized electronic navigational charts. Recent technologies have made available paper charts which are printed ...
The Office of Coast Survey employs about 250 United States Government employees and about 50 contractor personnel. [3] It is organized into four components: [3] The Marine Chart Division, responsible for processing nautical data, producing raster, paper, and electronic charts, and making critical corrections to charts.
Currently, the best source for nationwide LiDAR availability from public sources is the United States Interagency Elevation Inventory (USIEI). [1] The USIEI is a collaborative effort of NOAA and the U.S. Geological Survey, with contributions from the Federal Emergency Management Agency, the Natural Resources Conservation Service, the US Army Corps of Engineers, and the National Park Service.
The National Oceanic and Atmospheric Administration (abbreviated as NOAA / ˈ n oʊ. ə / NOH-ə) is an American scientific and regulatory agency charged with forecasting weather, monitoring oceanic and atmospheric conditions, charting the seas, conducting deep-sea exploration, and managing fishing and protection of marine mammals and endangered species in the US exclusive economic zone.
The National Environmental Satellite, Data, and Information Service (NESDIS) was created by the National Oceanic and Atmospheric Administration (NOAA) to operate and manage the United States environmental satellite programs, and manage the data gathered by the National Weather Service and other government agencies and departments.

NOAA Big Data Project: NOAA generates tens of terabytes of data a day from satellites, radars, ships, weather models, and other sources. While these data are publicly available, it is difficult to download and work with such high volumes. NOAA’s vast wealth of data therefore represents a substantial untapped economic opportunity.
