Final Thoughts on Feature Representation
We have gone over only the fundamentals of features and topology in the DRM. The DRM's topology mechanism can specify more detailed connectivity information.
A structurally similar mechanism, geometry topology, exists in the DRM, but serves the somewhat different function of explicitly capturing adjacency and containment relationships for geometric primitives rather than necessarily things in the environment.
For further information on features and topology, attend the terrain representation portion of the Advanced Application of the DRM tutorial.
