Topology Level Codelist

The value domain of Topology Level Codelist is defined in the following table.


# Code English Name Definition Source
1 geometryOnly Geometry Only Geometry objects without any additional structure which describes topology.
2 topology1D Topology 1D 1-dimensional topological complex - commonly called "chain-node" topology
3 planarGraph Planar Graph 1-dimensional topological complex that is planar. A planar graph is a graph that can be drawn in a plane in such a way that no two edges intersect except at a vertex.
4 fullPlanarGraph Full Planar Graph 2-dimensional topological complex that is planar (A 2-dimensional topological complex is commonly called "full topology" in a cartographic 2D environment)
5 surfaceGraph Surface Graph 1-dimensional topological complex that is isomorphic to a subset of a surface. A geometric complex is isomorphic to a topological complex if their elements are in a one-to-one, dimensional- and boundary-preserving correspondence to one another.
6 fullSurfaceGraph Full Surface Graph 2-dimensional topological complex that is isomorphic to a subset of a surface.
7 topology3D Topology 3D 3-dimensional topological complex. A topological complex is a collection of topological primitives that are closed under the boundary operations.
8 fullTopology3D Full Topology 3D complete coverage of a 3D Euclidean coordinate space
9 abstract Abstract topological complex without any specified geometric realisation.
