Coast Survey receives over 6,000 digital and hard copy chart source documents annually. Each is reviewed for its suitability for updating one or more raster nautical chart, NOAA ENC®, or U.S. Coast Pilot® products. Of these, about 18,000 separate chart compilations are assigned to be carried out by Coast Survey’s federal employee and contract cartographers.
Of all the natural and manmade features depicted on NOAA nautical charts, the four types that change the most, and for which Coast Survey receives the most source material, are:
These account for over 70% of the source applications assigned. The remaining source material is provided by a variety of other federal, state and local government agencies, national and international regulatory organizations, private companies, professional organizations, and private citizens.
