Definition |
An instance of this DRM class specifies an aggregation of <DRM Feature Hierarchy> objects in which each <DRM Feature Hierarchy> component represents a branch of a quadrant. The quadrant represented by a branch is specified by the <DRM Quadrant Data> instance associated with that branch. The bounding region that the <DRM Feature Hierarchy> components occupy is defined by the <DRM Spatial Extent> instance of the <DRM Quadrant Related Features> instance. |

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 This relationship exists to support attributes for derived objects. That is, these components are used only to specify texture mapping information for geometry that is to be derived from the <DRM Aggregate Feature> by the consumer. These <DRM Image Mapping Function> instances shall use <DRM Image Anchor> components to specify the mapping. 8 This is needed for cases in which an <DRM Aggregate Feature> is significant only for a particular domain, such as radar. |
