Borden System

(north of 62 degrees each minor block represents 20 minutes of longitude)

Because the distance between lines of longitude get smaller with increasing latitude, the Borden System changes at 64 degrees north latitude, from a width of 4 degrees of longitude to a width of 8 degrees in order to keep the area within each designate roughly the same.

Francis Beaufort

Whereas other wartime officers sought leisurely pursuits, Beaufort spent his leisure time taking soundings and bearings, making astronomical observations to determine longitude and latitude, and measuring shorelines.

Hooded carpetshark

The hooded carpetshark, Hemiscyllium strahani, is a bamboo shark in the family Hemiscylliidae found around Irian Jaya and Papua New Guinea, between latitudes 5° S and 10° S, and longitude 144° E and 153° E.

Maidenhead Locator System

In 1985, the Radio Society of Great Britain published a small set of BASIC language routines to convert from locator references to geographical coordinates (latitude and longitude) for further processing.

Marine chronometer

The Dutch scientist Gemma Frisius was the first to propose the use of a chronometer to determine longitude in 1530.
