  • TopologyTableRelation

    v1 v1  
     1Each postgis topology contains a "relation" table which defines the composition of every TopoGeometry bound to the topology. For each !TopoGeometry you have a set of element_type/element_id components. Interpretation of "element_type" depends on [wiki:TopologyTableLayer layer] definition: it is 1:Node, 2:Edge, 3:Face for non-hierarchical layers and a layer identifier for hierarchical layers.
