30、national 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 simpl

31、e 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 prof

32、ile 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 specifica

33、tions 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 example

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

43、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

44、.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 cl

45、asses 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).

46、s are the same as in ISO 19107: Coordinate Reference System (ISO 19107:2003, 6.2.2.17); association “Composition” between GM_CompositeCurve and GM_OrientableCurve (ISO 19107:2003, Figure 28). 5.5.2 Segmentation between GM_Curve and GM_CurveSegment The association “Segmentation” between GM_Curve and

47、GM_CurveSegment (ISO 19107:2003, 6.3.16.3) is changed as follows: the multiplicity of the “curve” role is restricted from 0,1 to 1, and the multiplicity of the “segment” role is restricted from 1n to 1. Instances of GM_CurveSegment thus cannot exist without being part of a GM_Curve. GM_CurveSegment:

48、curve1 : Reference (multiplicity restricted from 0,1) 5.5.3 Segmentation between GM_Surface and GM_SurfacePatch The association “Segmentation” between GM_Surface and GM_SurfacePatch (ISO 19107:2003, 6.3.17.3) is changed as follows: the multiplicity of the “surface” role is restricted from 0,1 to 1.

49、Instances of GM_SurfacePatch thus cannot exist without being part of a GM_Surface. GM_SurfacePatch:surface1 : Reference (multiplicity restricted from 0,1) 5.5.4 DirectPosition:coordinateReferenceSystem The multiplicity of the association role “coordinateReferenceSystem” of the data type DirectPosition (ISO 19107:2003, 6.4.1.4) is restricted from 0,1 to 0. As a consequence, individual points cannot specify a reference system; this has to be established
