Title
Standard representation of geographic point location by coordinates
International Organization for Standardization
Publication Date:
Jul 15, 2008
Scope:
This International Standard is 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 may be associated with
horizontal coordinates. Representation includes units of measure
and coordinate order.
This International Standard is not applicable to the
representation of information held within computer memories 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 that decimal degrees be
used. It allows the use of sexagesimal notations: degrees, minutes
and decimal minutes or degrees, minutes, seconds and decimal
seconds.
This International Standard does not require special internal
procedures, file-organization techniques, storage medium,
languages, etc., to be used in its implementation.
