<br/>
I´m trying to build a linear application (topology network) with PostGIS 2.0.0SVN.<br/>
<br/>
My real world situation has crosses edges with no nodes (water lines or hiqh voltage power lines in different heights or levels, where both edges have nothing to do with each other).<br/>
<br/>
Topo-Geo assumes full planar topology and gives me an error on this crossing edges.<br/>
(SQL/MM Spatial exception - egometry crosses an edge)<br/>
<br/>
The only possiblity I see at the moment to build it up in different topology schemas, which would be ok for example between water lines and low voltage cables, but not between high voltage power lines themselves.<br/>
<br/>
Is it possible with PostGIS 2.0 (at the moment) to build up this situation within on topology schema?<br/>
<br/>
If yes - how?<br/>
If no - will it come up in future versions?<br/>
<br/>
Thanks a lot for your answer,<br/>
