Standard representation of geographic point location by coordinates (ISO 6709:2008, including Cor 1:2009)

ISO 6709:2008 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 can be associated with horizontal coordinates. Representation includes units of measure and coordinate order.
ISO 6709:2008 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.
ISO 6709:2008 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, ISO 6709:2008 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.
ISO 6709:2008 does not require special internal procedures, file-organization techniques, storage medium, languages, etc., to be used in its implementation.

Standarddarstellung für geographische Punkte durch Koordinaten (ISO 6709:2008, einschließlich Cor 1:2009)

Die vorliegende Internationale Norm ist auf den Austausch von Koordinaten anwendbar, die die Lage geographischer Punkte beschreiben. Sie legt die Darstellung von Koordinaten einschließlich geographischer Breite und Länge fest, die beim Datenaustausch zu verwenden sind. Außerdem legt sie die Lagedarstellung von horizontalen Punkten fest, bei der andere Koordinaten als Breitengrad und Längengrad verwendet werden. Ebenfalls festgelegt wird die Darstellung von Höhe und Tiefe, die Punkten mit Lagekoordinaten zugeordnet werden können. Diese Darstellung umfasst auch Maßeinheiten sowie die Reihenfolge der Koordinaten.
Diese Norm gilt nicht für die Darstellung von gespeicherten Informationen während der Datenverarbeitung und bei deren Anwendung in Registern von geodätischen Codes und Parametern.
Diese Internationale Norm unterstützt die Darstellung der Lage von Punkten durch die eXtensible Markup Language (XML), und da die Kompatibilität der vorliegenden Norm mit der früheren Fassung dieser Inter-nationalen Norm, ISO 6709:1983, erforderlich ist, darf auch eine einzelne alpha-numerische Zeichenkette (ein Textstring) verwendet werden, um Punkte zu beschreiben.
Für den Datenaustausch von Breitengrad und Längengrad zwischen Computern schlägt diese Internationale Norm allgemein vor, Dezimalgrad zu verwenden. Sie erlaubt auch die Verwendung sexagesimaler Notationen: Grad, Minuten und Dezimalminuten oder Grad, Minuten, Sekunden und Dezimalsekunden.
Diese Internationale Norm erfordert keine besonderen internen Abläufe, Dateiorganisationsmaßnahmen, Speichermedien, Programmiersprachen usw., die bei deren Implementierung anzuwenden sind.

Représentation normalisée des latitude, longitude et altitude pour la localisation des points géographiques (ISO 6709:2008, Cor 1:2009 inclus)

L'ISO 6709:2008 est applicable à l'échange des coordonnées décrivant la localisation de points géographiques. Elle spécifie la représentation des coordonnées, dont la latitude et la longitude, utilisées pour l'échange de données. En outre, elle spécifie la représentation de la localisation des points horizontaux en utilisant les types de coordonnées différents de la latitude et de la longitude. Elle spécifie aussi la représentation de la hauteur et de la profondeur qui peuvent être associées à des coordonnées horizontales. La représentation inclut l'ordre des unités de mesure et des coordonnées.
L'ISO 6709:2008 n'est pas applicable à la représentation des informations gardées dans les mémoires des ordinateurs pendant leur traitement et leur utilisation dans les enregistrements des codes et des paramètres géodésiques.
L'ISO 6709:2008 supporte la représentation de la localisation des points au moyen de XML (langage de balisage extensible) et, par respect de la nécessité de compatibilité avec l'édition précédente, l'ISO 6709:1983, elle permet l'utilisation d'une chaîne alphanumérique unique pour décrire la localisation des points.
Pour l'échange des données informatisées sur la latitude et la longitude, l'ISO 6709:2008 suggère généralement d'utiliser les fractions décimales de degrés. Elle permet l'utilisation des notations sexagésimales: les degrés, les minutes et les fractions décimales de minutes ou les degrés, les minutes, les secondes et les fractions décimales de secondes.
L'ISO 6709:2008 ne comporte pas d'exigences spécifiques concernant les procédures internes, les techniques d'organisation des fichiers, les moyens de sauvegarde, les langages, etc. pour sa mise en oeuvre.

ISO 6709:2008(E)
Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 6709 was prepared by Technical Committee ISO/TC 211, Geographic information/Geomatics.
This second edition cancels and replaces the first edition (ISO 6709:1983), which has been technically revised.
The first edition provided for the representation of latitude and longitude for geographic point locations. This
second edition extends the use of the representation to applications requiring latitude or longitude values to be
quoted separately, for example when quoting a difference in two meridian values. It also extends the
representation of latitude and longitude to allow the values for each to be held in separate numeric fields.
This second edition additionally provides for the representation of horizontal point location by coordinates
other than latitude and longitude, and makes provisions for a variable-length format which has the flexibility to
cover these various requirements. It also includes provisions for heights and depths.
This second edition is primarily intended for data interchange between computer systems. Informative
Annex D, which summarises the different requirements at the human interface, has been added.
The first edition used the term altitude to describe vertical position. This International Standard uses the more
general term height and also allows for vertical location to be described as depth.

ISO 6709:2008(E)
Introduction
Efficient interchange of geographic-point-location data requires formats which are universally interpretable and
which allow identification of points on, above and below the earth’s surface. Users in various disciplines may
have different requirements. This is exemplified by the use of degrees and decimal degrees, as well as the
traditional degrees, minutes and seconds, for recording latitude and longitude. Users may also require various
levels of precision and may use latitude and longitude without height.
The use of this International Standard will
a) reduce the cost of interchange of data,
b) reduce the delay in converting non-standard coding structures in preparation for interchange by providing
advance knowledge of the standard interchange format, and
c) provide flexible support for geographic point representation.
