As stated in the Mariners Handbook and subsequent accident report: Every chart is liable to be incomplete". It belongs to the so-called plane chart model, where observed latitudes and magnetic directions are plotted directly into the plane, with a constant scale, as if the Earth's surface were a flat plane Portuguese National Archives british admiralty chart symbols Torre do Tombo, Lisbon The Mercator projection is used on the vast majority of nautical charts.

Most charts include a compass rose depicting the variation between magnetic and true north. However, the use of the Mercator projection is not without its drawbacks.

Mercator's technique was to make the lines of longitude parallel. On the real globe, the lines of longitude converge as one goes north or south away from the equator, until they meet at the pole. This distortion means that horizontal distances are exaggerated.

Mercator's solution, british admiralty chart symbols as it might be, was to british admiralty chart symbols the distance between lines of latitude in proportion; in a Mercator's projection map, a square is a square no matter where you are on the chart, but a square on the Arctic Circle is much bigger than a square at the equator, even though both occupy the same number of degrees on the globe.

The result of this is that scale in a nautical chart is dependent on latitude. In practical use, this is less of a problem than it sounds.
