General Information about Nautical Charts and Hydrography:
A nautical chart is a graphic representation of a sea area and adjacent coastal regions. Nautical charts are essential tools for marine navigation and are based on hydrographic surveys. Nautical charts are issued by power of the national hydrographic offices in many countries. These charts are considered "official" in contrast to those made by commercial publishers.  Hydrography is the branch of applied sciences which deals with the measurement and description of the physical features of oceans, seas, coastal areas, lakes and rivers.  The primary purpose is safety of navigation, as well as support of other marine activities including security and defense.  The origins of hydrography lay in the making of charts to aid navigation, by individual mariners as they navigated into new waters. These were usually private property of individuals who used them for commercial or military advantage.  As transoceanic trade and exploration increased, the commissioning of surveys was increasingly done by governments and special hydrographic offices. National organizations, particularly Navies, realized that the collection, systematization and distribution of this knowledge gave it great organizational and military advantages.  Thus were born dedicated national hydrographic organizations for the collection, organization, publication and distribution of nautical charts.  The United Kingdom Hydrographic Office is one of the oldest, supplying a wide range of charts covering the globe to other countries, allied military organizations and the public.  In the United States, the hydrographic charting function has been carried out since 1807 by the Office of Coast Survey of the National Oceanic and Atmospheric Administration within the U.S. Department of Commerce.
