Applicable to the interchange of coordinates describing geographic point location. It specifies the representation of coordinates, including latitude and longitude, to be used in data interchange. It additionally specifies representation of horizontal point location using coordinate types other than latitude and longitude. It also specifies the representation of height and depth that can be associated with horizontal coordinates. Representation includes units of measure and coordinate order. Not applicable to the representation of information held within computer memories during processing and in their use in registers of geodetic codes and parameters. Supports point location representation through the eXtensible Markup Language (XML) and, recognizing the need for compatibility with the previous version, allows for the use of a single alpha-numeric string to describe point locations. For computer data interchange of latitude and longitude, generally suggests that decimal degrees be used. It allows the use of sexagesimal notations: degrees, minutes and decimal minutes or degrees, minutes, seconds and decimal seconds.
