適用范圍：This International Standard is applicable to the interchange of coordinates describing geographic pointlocation. It specifies the representation of coordinates, including latitude and longitude, to be used in datainterchange. It additionally specifies representation of horizontal point location using coordinate types otherthan latitude and longitude. It also specifies the representation of height and depth that may be associatedwith horizontal coordinates. Representation includes units of measure and coordinate order.This International Standard is not applicable to the representation of information held within computermemories during processing and in their use in registers of geodetic codes and parameters.This International Standard supports point location representation through the eXtensible Markup Language(XML) and, recognizing the need for compatibility with the previous version of this International Standard,ISO 6709:1983, allows for the use of a single alpha-numeric string to describe point locations.For computer data interchange of latitude and longitude, this International Standard generally suggests thatdecimal degrees be used. It allows the use of sexagesimal notations: degrees, minutes and decimal minutesor degrees, minutes, seconds and decimal seconds.This International Standard does not require special internal procedures, file-organization techniques, storagemedium, languages, etc., to be used in its implementation.
