  • <DRM Feature Topology>

Superclass

Subclass

Definition

The objects that define both the geometric (i.e., location, shape) and topological (i.e., adjacency) aspects of <DRM Features>, including <DRM Feature Nodes>, <DRM Feature Edges>, and <DRM Feature Faces>. A topological surface consists of a collection of <DRM Feature Topology> instances related to one another through a variety of topological relationships.

Example(s)

  • In a collection of <DRM Feature> instances representing a transportation network, the <DRM Feature Face> instances represent built-up areas, airfields, railroad yards, and parking lots, the <DRM Feature Edge> instances represent their boundaries as well as roads, railroads, and runways, and the <DRM Feature Node> instances represent road intersections and railroad crossings.
