Example(s)

  • A terrain region representing a road network might be broken up into four rectangular tiles. While the <DRM Polygon> instances representing roads are allowed to extend across the tile boundaries, the <DRM Geometry Topology> instances that are located within each tile are organized into separate <DRM Union Of Geometry Topology> instances to support access by spatial location.
