  • <DRM Linear Feature>

Superclass

Subclass
  • None.

Definition

An instance of this DRM class is a <DRM Primitive Feature> with a one-dimensional structure, such as a road, a stream, or a power line.

Clarifications

1 An association between two <DRM Feature Representation> instances indicates that the environmental object(s) that they represent have the semantic relationship indicated by the <DRM Base Association Data> instance on the association relationship.

2 An association between a <DRM Geometry Hierarchy> instance and a <DRM Feature Representation> instance indicates that the environmental object(s) that they represent have the semantic relationship indicated by the <DRM Base Association Data> instance on the association relationship.

3 An association between a <DRM Property Grid> instance and a <DRM Feature Representation> instance indicates that the environmental object(s) represented by the <DRM Feature Representation> instance and the <DRM Property Grid> instance (or some specific cell data within that <DRM Property Grid> instance) have the semantic relationship indicated by the <DRM Base Association Data> instance on the association relationship. Each associated <DRM Property Grid> instance will indicate whether the entire <DRM Property Grid> instance or only some specific cell data within it is participating in the relationship in question.

4 An association between two <DRM Feature Representation> instances indicates that the environmental object(s) that they represent have the semantic relationship indicated by the <DRM Base Association Data> instance on the association relationship.

5 An association between a <DRM Geometry Hierarchy> instance and a <DRM Feature Representation> instance indicates that the environmental object(s) that they represent have the semantic relationship indicated by the <DRM Base Association Data> instance on the association relationship.

6 An association between a <DRM Property Grid> instance and a <DRM Feature Representation> instance indicates that the environmental object(s) represented by the <DRM Feature Representation> instance and the <DRM Property Grid> instance (or some specific cell data within that <DRM Property Grid> instance) have the semantic relationship indicated by the <DRM Base Association Data> instance on the association relationship. Each associated <DRM Property Grid> instance will indicate whether the entire <DRM Property Grid> instance or only some specific cell data within it is participating in the relationship in question.

7 These components support attributes for derived objects; that is, they are used only to specify texture mapping information for geometry that is derived from the <DRM Primitive Feature> by the consumer. These <DRM Image Mapping Function> components shall use <DRM Image Anchor> components to specify the mapping.

8 This is needed because in many cases, a <DRM Primitive Feature> may be significant only for a particular domain, such as radar.
