DIN EN ISO 19111-2:2012-06 EN ISO 19111-2:2012 (E) 4 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 posit
27、ion 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-d
28、imensional 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
29、 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 includ
30、e 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. DIN EN ISO 19111-2:2012-06 EN ISO 19111-2:2012 (E) 5 1 Scope This part of ISO 19111 specifies the conceptual schema for the descriptio
31、n 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 tim
32、e. 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
33、 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 lat
34、est edition of the referenced document (including any amendments) applies.

39、erencing is modelled with the Unified Modelling Language (UML). The basic data types and UML diagram notations are defined in ISO/TS 19103 and ISO/IEC 19501. 5.3 Attribute status In this part of ISO 19111, attributes are given an obligation status: Obligation Definition Meaning M Mandatory This attr
40、ibute shall be supplied. O Optional This attribute may be supplied. In Tables 1 to 3, the “Maximum occurrence” column indicates the maximum number of occurrences of attribute values that are permissible, with “N” indicating no upper limit.

41、o-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 coor
42、dinate 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 a
43、ccommodate 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 t
44、o 6.3 and 6.4. Table 1 specifies the attributes of a parametric coordinate reference system inherited from SC_SingleCRS.

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.
