Combining LRS and Topology Geometry Network?

Question

Hi,
Is it possible to combine the LRS Network and Topology Model ?
e.g. to create a Topology Geometry Network and which uses LRS Geometries ?
some details:
I used the command SDO_NET.CREATE_TOPO_NETWORK(‘TEST_NET’, 1, true, false);
The following table was created:
TEST_NET_LINK$ with a column named TOPO_GEOMETRY of Type mdsys.SDO_TOPO_GEOMETRY
now my Questions:
- Where do I store the actual mdsys.SDO_GEOMETRY
Object ? (is there a default table?)
- Can this Geometry be of type LRS ?
Thank you
Marco

Answer 1

The Network Data Model can work with either LRS geometries or data stored in the topology data model, but not both.
The topology data model does not work with LRS geometries.
Depending on how you are generating the measure values in your lrs data, you may be able to recreate the measure values whenever you change the definition in a topology, and store the lrs data as genererated geometry data in a separate table using get_geometry() and convert_to_lrs_geometry
