Coordinates refer to a system by which a position may be uniquely designated. In the context of geocaching, it refers to the location of a geocache.

[edit] Composition

In three-dimensional space, a coordinate must be given in terms of three independent variables. In the context of geocaching, where it is usually assumed that the geocache is sufficiently close to the earth's surface, only two variables are needed, often referred to as latitude and longitude.

[edit] Format

Each designation of a coordinate can be given in terms of some unit system. In most cases within geocaching, the latitude and longitude are written in degrees and minutes. On geocaching.com, the most common format used is ddd° mm.mmm'.

[edit] Data

Several differing data are used in designating coordinates, based on geographical surveys. The most frequently used datum set is WGS84 as it tends to be the most recent survey.
