hello!

I'm trying to correct some topology errors of a line, point or polygon layer.

First, I've tried with a commercial solution from ESRI, by using topology rules within a geodatabase.

But, it only validates the current topology, generating an error report so I can be aware of issues and have the opportunity to repair serious errors. In this way, topology only helps me to see the error and to repair it manually. If the cluster tolerance is set properly, some errors can be corrected.

My task is to automatically correct and repair topology errors, such as no snapping features, overlapping, etc., in conclusion any topology rules which I can define.

Can you please suggest any other software solution (preferable a free or open-source solution).

Thanks!

Sincerely,
Adrian

There's MRF software, plugins for Arc, Geomedia and FME, that can do most or all of these things. It's not a free product though.

Not free, but relatively cheap, is Manifold GIS.

Here's the Manifold help page on it's capabilities.

If the featureclass are in polygons, you can export them to coverage and build them labels. This way you can identify the errors. That helps me a lot to find the errors that topology do not detect like you said. I am not sure of a good software that you were looking.

Maptitude automatically enforces topology and when importing non-topological layers such as Shapefiles, you have several options to choose from to handle bad topology.
