What is a nautical chart?

Cartography:
Cartography plays a crucial role in the creation and use of nautical charts. Cartography uses precise survey data to accurately represent the shape, contours, and characteristics of the land sea interface.

Nautical Chart:
Nautical charts are specialized maps designed for navigation in marine environments. They provide detailed information about water depths, coastline features, navigational aids, and hazards. You can buy nautical charts from Garmin, Humminbird, B&G, Navionics, and C map.
A nautical chart, also known as a marine chart or sea chart, is a specialized map used by mariners for navigation and safe passage at sea. It provides detailed information about the coastal areas, waterways, depths, and hazards in a specific maritime region. Nautical charts are essential tools for sailors, fishermen, and other maritime professionals to navigate safely and efficiently.

Nautical charts are typically produced by national hydrographic offices or other authorized agencies. They are created using accurate surveying techniques, including depth soundings, shoreline measurements, and data from satellite and aerial surveys. The information is then compiled and presented on the chart in a standardized manner.
These indicate the water depths at specific locations, allowing mariners to assess whether their vessel can safely navigate in a particular area.
The chart shows the shape and features of the coastline, including landmarks, lighthouses, and other prominent structures. These visual references help mariners identify their position and make accurate navigation decisions.
Nautical charts depict buoys, beacons, and other navigational aids that assist mariners in determining their position and following established shipping routes.
