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

#	Code	English Name	Definition
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.
