Associations Between Terrain Representations
Multiple terrain representations can be associated with one another:
- Feature-to-Feature
- Feature-to-Geometry Hierarchy
- Feature-to-Property Grid
- Geometry Hierarchy-to-Geometry Hierarchy
These associations may have an attached semantic meaning:
- Spatial:
- Alternate Representation – different representations of the same thing
- Spatial Relationships – describes relative positions
- Disjoint/Intersect, Touch, Contains/Contained By, Overlap, Cross
- Above/Below – complete or partial horizontal overlap
- Proximity – within a specified distance of one another
- Functional:
- Controls/Controlled By – acts to influence state or position
- Supports/Supported By – acts to maintains position
- Attached – resist movement relative to one another
