I have some edges and centroids with some atributes.
I imported edges to topo using TopoGeo_AddLineString.
And I polygonized toposchema.
I want to create relation with polygons with centroid attribute table.
I can do something like
'topo', topology.GetFaceByPoint('topo', geom,
) geom FROM centro;
For obtain face geometry.
But if I want have topogeometry, I need to create normal geometry and
create topogeometry from this.
Is there another way, how to create topogeometry from face id?
I can insert face id into topo.relation and create topogeometry from this
by query, but is it a right way? Can I used some functionality in topology
for doing this.
