What is a bathymetric map?

Bathymetric map is a map that measures the depth of water through the underwater area. Although many people think of bathymetric maps as ocean depth measurement, this type of mapping can also apply to the sea and lakes. Bathymetric map is a lot like a topographic map, except that the features contained in it are under water. It can use various representations, including color and outline lines, to represent the ocean or the sea in a particular area. Some bathymetric maps use what is called the digital terrain (DTM) to show how underwater depth levels differ in the area.

When the cartographers began to produce bathymetric maps, the depth was often found by reducing a certain type of physical probe down into the water. This method could be time consuming and inaccurate. In modern times, this method was replaced by Sonar to give map manufacturers a much better picture of what's on the bottom of the ocean.

Bathymetric map can serve many different functions. Many of these types of maps give navigators a better understanding of underwater elements that could endanger the safety of a particular sea path for a ship or ship. Bathymetric map can also be useful in diving missions, where search parties want to identify something located on an ocean or seabed, from a lost ship to drain. Many interesting underwater diving missions that have discovered long -term treasures or famous lost ships took advantage of the benefits of bathymetric mapping to make the underwater location easier. Bathymetric mapping is also used for "paleobathymetry", studying ancient changes in underwater topography.

Although many different nations have their own institutes for compile data on bathymetric maps, there is an international source called the general bathymetric chart of the oceans (Gebco). This collection of bathymetric maps can provide a large amount of ocean floors anywhere in the world. ProjectionT is the head of the Intergovernmental Oceanographic Commission (IOC), which is part of the International Educational, Scientific and Cultural Organization of the UN (UNESCO). The Gebco collection helps scientists around the world to provide top research on something that many people still know relatively little: what lies under the largest water units in the world. Progressive Bathymetric mapping helps to discover the secrets from one of the last borders of an increasingly known country.
