Nautical chart production

A nautical chart is a navigational guide map that shows water depths, rocks, underwater obstacles, the shapes of islands, port facilities, lighted buoys, offshore targets, tides/tidal currents/ocean currents for the safety of vessels at sea. Therefore, it is produced scientifically through very accurate surveying. Recently, in fact, we began publishing electronic navigational charts equipped to which state-of-the-art technologies are applied.

Nautical Chart Classification

The nautical chart is divided into navigational and miscellaneous charts, depending on usage.

Nautical chart

Generally speaking, this chart means a navigational chart because of many different types of publications along with widespread use.

General chart

This chart is used for long-distance voyages and navigation planning because one chart covers a wide range of regions on the globe. As a small-scale map, it has the scale of 1: 4,000,000 or less.

Sailing chart

This is usually intended for a long-distance voyage and shows offshore water depths, main lighthouses/light buoys, and inland targets viewed offshore from a distance. As a small-scale map, it has the scale of 1: 1,000,000 or less.

General chart of coast

This is intended for inshore coastwise safe navigation with the small scale of 1: 300,000 or less.

Coastal chart

This chart intended for coastal navigation depicts coasts in detail and is used most in Korea. As a small-scale map, it has the scale of 1: 75,000 or less.

Harbor chart

Targeting narrow areas such as ports, anchorages, fishery harbors, and straits, this chart depicts facilities where vessels can be berthed in detail. As a large-scale map, it has the scale of 1:50,000 or more.

Miscellaneous chart

This is a chart used for reference during sailing, scientific research, production and resource development.

Fishery chart

This is produced by diagramming general data needed in every fishing industry on a general navigational chart, with the letter of “F” before chart numbers.

Special charts

There are the plotting sheet, the territorial chart, the global navigation and the planning chart, and more.
