Example(s)

  • The geographic extent of a thematic coverage might be divided up into a collection of tiles. Due to political boundaries or shorelines, some of these tiles might have irregular shapes. The <DRM Feature Topology> instances contained within each tile would be organized into one of the components of a <DRM Perimeter Related Feature Topology> instance.
