Latlon

Latlon is a method of expressing geographical coordinates, specifically the location of a point on the Earth's surface, using a combination of latitude and longitude values.

Latitude refers to the angular distance north or south of the Earth's equator, measured in degrees, minutes, and seconds. Latitude values range from 0° at the equator to 90° at the poles, with positive values indicating locations north of the equator and negative values indicating locations south of the equator.

Longitude, on the other hand, refers to the angular distance east or west of the Greenwich meridian, also measured in degrees, minutes, and seconds. Longitude values range from 0° at the Greenwich meridian to 180° at the international date line, with positive values indicating locations east of the meridian and negative values indicating locations west of the meridian.

In the Latlon system, a location is expressed as a pair of coordinates, consisting of a latitude value and a longitude value. For example, the latitude and longitude of New York City are approximately 40.7128° N and 74.0060° W, respectively. This coordinate pair allows for precise location determination and is widely used in geographic information systems (GIS), mapping, and navigation applications.

The Latlon system is based on the World Geodetic System (WGS) 1984, a standard reference ellipsoid used for mapping and navigation. This system provides a consistent and accurate method for expressing geographical coordinates, enabling global positioning and navigation systems to function reliably.
