Geographic information - Spatial referencing by coordinates - Part 2: Extension for parametric values (ISO 19111-2:2009)

ISO 19111-2:2009 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 ISO 19111-2:2009 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 ISO 19111-2:2009.

Geografske informacije - Lociranje s koordinatami - 2. del: Razširitev za parametrične vrednosti (ISO 19111-2:2009)

Ta del standarda ISO 19111 določa zasnovno shemo za opis lociranja s parametričnimi vrednostmi ali funkcijami. Shemo standarda ISO 19111 uporablja za združevanje položaja, določenega s koordinatami s parametrično vrednostjo, za oblikovanje prostorsko-parametričnega koordinatnega referenčnega sistema (CRS). Prostorsko-parametrični koordinatni referenčni sistem se po izbiri lahko razširi in vključuje še čas. Ciljni uporabniki tega dela standarda ISO 19111 so izdelovalci in uporabniki okoljskih informacij. Parametrov, ki so atributi prostorskih lokacij ali lastnosti, vendar niso zajeti v njihovo lociranje, ta del standarda ISO 19111 ne obravnava.

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:

SIST EN ISO 19111-2:2012
ISO 19111-2:2009(E)
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.

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

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.

6.3 Parametric coordinate system
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.

6.5 Spatio-parametric coordinate reference system
ISO 19111 describes the concept of, and UML schema for, a compound coordinate reference system (CCRS).
A spatio-parametric coordinate reference system shall be a compound CRS in which one component is a
geodetic 2D, projected or engineering 2D CRS, supplemented by a parametric CRS to create a
three-dimensional CRS. See Figure 4. An example is included in Annex B.
The geodetic 2D CRS may be the horizontal component of a geodetic 3D CRS.

Using the provisions of ISO 19111, any of the above-listed combinations forming a spatio-parametric CRS
may be associated with a temporal CRS, as described in ISO 19108, to form a spatio-parametric-temporal
CCRS. More than one temporal coordinate reference system may be included if these axes represent different
time quantities. Nesting of CCRS shall not be permitted — the individual single systems shall be aggregated
together. Figure 5 shows the possible composition of a spatial, a parametric and a temporal CRS in a spatio-
parametric-temporal CCRS.
