Dear All, As a Qgis user,I have always wished there were ways to efficiently view and fix existing topological errors in data. As I researched a bit, there were some developments going around 3 years ago in this regard. I found a source too in Martin Dobias' Github repository.
If nobody is currently working on it, I would be happy to support the integration of this to Quantum GIS. I have done something similar in a popular 2-D drafting application using NetTopologySuite(a c# port of Java Topology Suite) as a hobby project. Since GEOS is also a port of JTS, things might be comfortable. As I took a quick look at the code, it seems to be very close to completion. Though I am not a hardcore C++ developer, I am sure my C# experience would guide me to work on this. best regards, Vinayan
