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. |
