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 19111-2 was prepared by Technical Committee ISO/TC 211, Geographic information/Geomatics.
ISO 19111 consists of the following parts, under the general title Geographic information — Spatial
referencing by coordinates:

Introduction
ISO 19111 describes the elements necessary to fully define various types of reference systems used for
spatial referencing by coordinates. In ISO 19111, a coordinate is one of n scalar values that define the position
of a point. ISO 19111 allows for coordinates which are angular, such as latitude and longitude, or linear, such
as easting and northing. It also describes the concept of a compound coordinate reference system, which
uses at least two independent coordinate reference systems to describe a three-dimensional spatial position.
Scientific communities, especially those concerned with the environmental sciences, frequently express
spatial position partially in terms of a parameter or function. Within these communities, this parameter or
function is treated as a coordinate. Its relationship with a spatial dimension will usually be non-linear.
Examples are widespread, but latitude, longitude and pressure is a commonly encountered example.
This part of ISO 19111 defines a parametric coordinate reference system using the concepts of ISO 19111.
The provisions of ISO 19111 are then used to include a parametric coordinate reference system as part of a
compound coordinate reference system. Optionally, time can also be included as an additional axis or as
axes.

6 Spatio-parametric referencing
6.1 Overview
ISO 19111 defines a coordinate reference system (CRS) as a coordinate system which is related to an object
(such as the Earth) by a datum. A coordinate system (CS) is a set of mathematical rules for specifying how
coordinates are to be assigned to points. A coordinate system will have one or more axes. A datum defines
the position of the origin, the scale, and the orientation of a coordinate system. ISO 19111 describes several
subtypes of coordinate reference system, coordinate system and datum. This part of ISO 19111 defines a
further subtype of each to accommodate parametric referencing.
6.2 Parametric coordinate reference system
A parametric coordinate reference system shall be a subtype of a single CRS. Figure 1 shows the UML
schema, which shall consist of one parametric coordinate system and one parametric datum, these elements
being according to 6.3 and 6.4.
Table 1 specifies the attributes of a parametric coordinate reference system inherited from SC_SingleCRS.

A coordinate system shall be of the parametric type if a physical or material property or function is used as the
dimension. The parameter can be measured or could be a function defined in other contexts, but in parametric
coordinate systems it forms the coordinate system axis.
EXAMPLE 1 Pressure in meteorological applications
EXAMPLE 2 Density (isopycnals) in oceanographic applications.
A parametric coordinate system shall be a subtype of a coordinate system and shall be used as a part of a
parametric coordinate reference system. Figure 2 shows the UML schema and Table 2 describes the
attributes, inherited from CS_CoordinateSystem, as defined in ISO 19111.
A parametric coordinate reference system shall be one-dimensional and shall have one axis. The defining
elements are described in ISO 19111:2007, Tables 27 and 28.

Avant-propos
L’ISO (Organisation internationale de normalisation) est une fédération mondiale d’organismes nationaux de
normalisation (comités membres de l’ISO). L’élaboration des Normes internationales est en général confiée aux
comités techniques de l’ISO. Chaque comité membre intéressé par une étude a le droit de faire partie du comité
technique créé à cet effet. Les organisations internationales, gouvernementales et non gouvernementales,
en liaison avec l’ISO participent également aux travaux. L’ISO collabore étroitement avec la Commission
électrotechnique internationale (CEI) en ce qui concerne la normalisation électrotechnique.
Les Normes internationales sont rédigées conformément aux règles données dans les Directives ISO/CEI, Partie 2.
La tâche principale des comités techniques est d’élaborer les Normes internationales. Les projets de Normes
internationales adoptés par les comités techniques sont soumis aux comités membres pour vote. Leur publication
comme Normes internationales requiert l’approbation de 75 % au moins des comités membres votants.

ISO 19111-2:2009(F)
Introduction
L‘ISO 19111 décrit les éléments nécessaires pour définir intégralement les différents types de systèmes
de références utilisés pour un référencement spatial par coordonnées. Dans l’ISO 19111, une coordonnée
est une valeur parmi n valeurs scalaires qui définissent la position d’un point. L’ISO 19111 tient compte des
coordonnées angulaires, comme latitude et longitude, ou linéaires, comme abscisse et ordonnée. Elle décrit
également le concept d’un système de coordonnées de référence combiné, qui utilise au moins deux systèmes
de coordonnées de référence indépendants pour décrire une position tridimensionnelle dans l’espace.
Les communautés scientifiques, en particulier celles concernés par les sciences de l’environnement, n’expriment
fréquemment une position dans l’espace que partiellement, en termes de paramètre ou de fonction. Au sein
de ces communautés, ce paramètre ou fonction est traité comme une coordonnée. Sa relation avec une
dimension spatiale sera habituellement non linéaire. Les exemples sont répandus, mais latitude, longitude et
pression représentent un exemple rencontré communément.
La présente partie de l’ISO 19111 définit un système de coordonnées de référence paramétriques utilisant
les concepts de l’ISO 19111. Les dispositions de l’ISO 19111 sont alors utilisées pour inclure un système de
coordonnées de référence paramétriques dans le cadre d’un système de coordonnées de référence combiné.
Éventuellement, le temps peut également être inclus comme axe(s) supplémentaire(s).

Supplément pour valeurs paramétriques
1 Domaine d’application
La présente partie de l’ISO 19111 spécifie le schéma conceptuel pour la description d’un système de références
spatiales utilisant des valeurs ou fonctions paramétriques. Il applique le schéma de l’ISO 19111 pour combiner
une position référencée par des coordonnées avec une valeur paramétrique pour former un système de
coordonnées de référence (CRS, coordinate reference system) spatio-paramétriques. Le système CRS spatio-
paramétriques peut éventuellement être étendu pour inclure le temps.
Les utilisateurs visés de la présente partie de l’ISO 19111 sont les créateurs et utilisateurs d’informations liées
à l’environnement.
Les paramètres qui sont des attributs d’emplacements ou entités spatiaux, mais qui ne sont pas impliqués dans
leur système de références spatiales, ne sont pas abordés dans la présente partie de l’ISO 19111.
2 Exigences relatives à la conformité
Tout système CRS pour lequel la conformité à la présente partie de l’ISO 19111 est revendiquée doit être
conforme à l’Annexe A.

d’occurrences des valeurs d’attributs, «N» signifiant l’absence de limite maximale.
6 Système de références spatio-paramétriques
6.1 Présentation
L’ISO 19111 définit un système de coordonnées de référence (CRS) comme un système de coordonnées lié
à un objet (comme la Terre) par une référence. Un système de coordonnées (CS) est un ensemble de règles
mathématiques servant à spécifier comment des coordonnées doivent être affectées à des points. Un système
de coordonnées aura un ou plusieurs axes. Une référence définit la position de l’origine, l’échelle et l’orientation
d’un système de coordonnées. L’ISO 19111 décrit plusieurs sous-types d’un système de coordonnées de
référence, d’un système de coordonnées et de référence. La présente partie de l’ISO 19111 définit un sous-type
supplémentaire pour chacun de ces éléments afin de s’adapter à un système de références paramétriques.

6.3 Système de coordonnées paramétriques
Un système de coordonnées doit être du type paramétrique si une propriété ou fonction physique ou matérielle
est utilisée comme dimension. Le paramètre peut être mesuré ou pourrait être une fonction définie dans d’autres
contextes, mais dans des systèmes de coordonnées paramétriques, il constitue l’axe du système de coordonnées.
EXEMPLE 1 La pression dans les applications météorologiques
EXEMPLE 2 La densité (isopycnique) dans les applications océanographiques.

ISO 19111 allows for coordinates which are angular, such as latitude and longitude, or linear, such as easting and northing. It also describes the concept of a compound coordinate reference system, which uses at least two independent coordinate reference systems to describe a three-dimensional spatial position. Scientific communities, especially those concerned with the environmental sciences, frequently express spatial position partially in terms of a parameter or function. Within these communities, this parameter or function is treated as a coordinate. Its relationship with a spatial dimension will usually be non-linear. Examples are widespread, but latitude, longitude and pressure is a commonly encountered example.
This part of ISO 19111 defines a parametric coordinate reference system using the concepts of ISO 19111. The provisions of ISO 19111 are then used to include a parametric coordinate reference system as part of a compound coordinate reference system. Optionally, time can also be included as an additional axis or as axes.

INTERNATIONAL STANDARD ISO 19111-2:2009(E) © ISO 2009 – All rights reserved PROOF/ÉPREUVE 1Geographic information — Spatial referencing by coordinates — Part 2: Extension for parametric values 1 Scope This part of ISO 19111 specifies the conceptual schema for the description of spatial referencing using parametric values or functions. It applies the schema of ISO 19111 to combine a position referenced by coordinates with a parametric value to form a spatio-parametric coordinate reference system (CRS). The spatio-parametric CRS can optionally be extended to include time. The intended users of this part of ISO 19111 are producers and users of environmental information. Parameters which are attributes of spatial locations or features, but which are not involved in their spatial referencing, are not addressed by this part of ISO 19111. 2 Conformance requirements Any CRS for which conformance to this part of ISO 19111 is claimed shall be in accordance with Annex A. 3 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the cited edition applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

ISO 19111-2:2009(E) © ISO 2009 – All rights reserved PROOF/ÉPREUVE 36 Spatio-parametric referencing 6.1 Overview ISO 19111 defines a coordinate reference system (CRS) as a coordinate system which is related to an object (such as the Earth) by a datum. A coordinate system (CS) is a set of mathematical rules for specifying how coordinates are to be assigned to points. A coordinate system will have one or more axes. A datum defines the position of the origin, the scale, and the orientation of a coordinate system. ISO 19111 describes several subtypes of coordinate reference system, coordinate system and datum. This part of ISO 19111 defines a further subtype of each to accommodate parametric referencing. 6.2 Parametric coordinate reference system A parametric coordinate reference system shall be a subtype of a single CRS. Figure 1 shows the UML schema, which shall consist of one parametric coordinate system and one parametric datum, these elements being according to 6.3 and 6.4.
