[postgis-users] Topology improvements, testing, funding

[Sandro Santilli]

Good evening data modelers,

this mail is to let you know that the topological support in the
upcoming PostGIS 2.0 has been improved thanks to the input from an
early tester, feeding topology constructor functions with pretty
dirty data.

The outcome of that experience is reported here:
http://strk.keybit.net/blog/2011/11/21/topology-cleaning-with-postgis/

Following this example I'd like to call you for further testing
as I know you're all willing to keep your data in a safe and clean
way and are thus looking forward to the new support.

The specific example reported in the article had to do with the sole
building of low-level topology (nodes, edges, faces), but there's 
more to PostGIS topology than that.

The PostGIS topology lets you express your features as a composition
of those primitives, embedded into a new data type (TopoGeometry) which
you can use wherever you would use your good old Geometry values.

>From the Zurich hackfest you can now also _see_ your TopoGeometry based
layers in QGis w/out having to create an ad-hoc view for it.

The hardest step for you to test use of TopoGeometry objects so far would
be converting your Geometry layers to TopoGeometry layers. This is what
ticket #1017 is willing to address [1]. The ticket is open looking for
co-funders.

Please keep in mind that feature-freeze for PostGIS-2.0 will happen
in a couple of week so any _new_ feature would need to be started 
before that. 

Thank you.
