Geographic information - Core profile of the spatial schema (ISO 19137:2007)
This International Standard defines a core profile of the spatial schema specified in ISO 19107 that specifies, in accordance with ISO 19106, a minimal set of geometric elements necessary for the efficient creation of application schemata. This International Standard supports many of the spatial data formats and description languages already developed and in broad use within several nations or liaison organizations.

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 19137 was prepared by Technical Committee ISO/TC 211, Geographic information/Geomatics.

ISO 19137:2007(E)
Introduction
This International Standard provides a core profile of the geometry part of the spatial schema specified in
ISO 19107 that is easy to understand and has a low cost of implementation. The profile is intentionally small
and limited in order to increase the chance of gaining widespread market acceptance.
A simple topology package extension of the profile might be developed as a future part of this International
Standard. Many user communities have requirements that go beyond the capabilities provided by this
International Standard, and they may define custom profiles.
While ISO 19136 also implements a profile of ISO 19107, it is a comprehensive profile, not a core profile.
This International Standard supports data types for geometric primitives of 0, 1 and 2 dimensions. It satisfies
the conformance test A.1.1.3 of ISO 19107:2003. It is in conformance class 1 of ISO 19106.
Annex A lists some specifications that were supported by this International Standard at the time of its
publication. Annex B specifies an abstract test suite for determining whether an application schema or profile
is conformant to the core profile. Annex C discusses how to extend the core profile. Annex D presents two
examples.

INTERNATIONAL STANDARD ISO 19137:2007(E)
Geographic information — Core profile of the spatial schema
1 Scope
This International Standard defines a core profile of the spatial schema specified in ISO 19107 that specifies,
in accordance with ISO 19106, a minimal set of geometric elements necessary for the efficient creation of
application schemata.
This International Standard supports many of the spatial data formats and description languages already
developed and in broad use within several nations or liaison organizations.
NOTE Data modelled with this International Standard are consistent with spatial models already developed and used
by a number of organizations; see Annex A.
2 Conformance
An abstract test suite for this International Standard is given in Annex B.
3 Normative references
The following referenced documents are indispensable for the application of this document. For dated
references, only the edition cited applies. For undated references, the latest edition of the referenced
document (including any amendments) applies.
ISO 19107:2003, Geographic information — Spatial schema
ISO 19111:2003, Geographic information — Spatial referencing by coordinates
4 Terms, definitions, symbols and abbreviated terms
For the purposes of this document, the same terms, definitions, symbols and abbreviated terms given in
ISO 19107 apply.
5 Geometry packages
5.1 Class diagram
Figure 1 depicts the complete profile of ISO 19107. The constraints on ISO 19107 are too many to be shown
graphically in Figure 1, but are described in 5.2 to 5.12. This International Standard is limited to applications in
which
⎯ there is a 1:1 mapping between features and geometric primitives,
⎯ all geometric primitives are referenced to a single coordinate reference system,
© ISO 2007 – All rights reserved 1
---------------------- Page: 10 ----------------------
ISO 19137:2007(E)
⎯ all curves are composed of line segments, and
⎯ all surfaces are composed of planar facets.
Figure 1 — The complete profile
Abstract classes that appear in Figure 1 and are needed to provide compatibility with ISO 19107 are omitted
from the simplified representation in Figure 2.
NOTE Abstract classes that are needed for compatibility with ISO 19107 have been omitted. Also, the inheritance
relation between GM_Ring and GM_Object is not shown here.

5.2 Omitted constructs
This International Standard uses no operations or interfaces from ISO 19107. Also, any other constructs from
ISO 19107 are omitted in this International Standard unless they are mentioned in 5.3.
5.3 Classes retained without additional constraints
The following classes are the same as in ISO 19107.
⎯ Abstract classes: GM_Object (ISO 19107:2003, 6.2.2); GM_Boundary (6.3.2); GM_PrimitiveBoundary
(6.3.4); GM_Primitive (6.3.10); GM_OrientablePrimitive (6.3.13); GM_Complex (6.6.2); GM_Composite
(6.6.3).
⎯ Concrete classes: GM_Ring (ISO 19107:2003, 6.3.6), GM_SurfaceBoundary (6.3.7); GM_Point (6.3.11);
GM_Curve (6.3.16); GM_Surface (6.3.17); DirectPosition (6.4.1); GM_PointArray (6.4.6); GM_LineString
(6.4.10).
Like ISO 19107, this International Standard refers to the abstract class SC_CRS, which is defined in
ISO 19111.
5.4 Concrete classes made abstract
The following classes are concrete in ISO 19107, but abstract in this profile: GM_OrientableCurve (6.3.14);
GM_OrientableSurface (6.3.15); GM_CompositeCurve (6.6.5).
