Coordinate systems are defined by identifiers. Identifiers have the format Type: Value. Depending on the type of identifier, the value has a different format:

EPSG

This type of identifier describes a coordinate system based on its EPSG code defined by the European Petroleum Survey Group. A coordinate code is defined using a code from a geographic system (GCS) or a projected system (PCS). The codes can be found at this address: http://www.epsg.org.

Example:

EPSG:4326(WGS84)

EPSG:23030(UTM 30N / ED50)

EPSG:32630(UTM 30N / WGS84)

EPSG:31463(DHDN / 3-degree Gauss zone 3)

PROJ4

Format used by the PROJ.4 library. More information can be found at this address: http://proj4.org/parameters.html.

Example:

PROJ4:+proj=utm +zone=30 +ellps=intl +units=m +no_defs
