Checking and cleaning vector topology
Miguel Iturralde
Hello everyone,
Does anyone know of a software or extension for checking and correcting topology problems from within MapInfo, or as a standalone for that matter, that could perform these tasks? I am referring to polyline objects not connecting or breaking at intersections, overshoots/dangles, etc. I remember a program called MapLogix by a company named Korem that was excellent for checking and fixing those issues, and it would also combine polylines based on or more attributes.
I’ve read that importing a map as a shapefile in QGIS and using the GRASS module v.clean.break is a working alternative, but that’s another ballgame, creating GRASS locations and mapsets. Hope there are some other alternatives.
Thanks and regards,
Miguel Iturralde

I have not tried it yet, but Routfinder and Routware have those network checking features.

Thanks Juan Pablo and Richard for the suggestions –I’ll definitely take a look at the PostGIS blog entry…

Postgis has topology and is a supported MapInfo database. This might be worth reading:
