[postgis-users] Magnifying Topology

[Jan Hartmann]

Perhaps this is the wrong list to ask, but I just read Martin Davis' column:

It's a tool for the Java Topology Suite (JTS) to discover small 
topological errors in a vector map. It solves a problem that I have 
suffered from during my whole GIS career: getting correct input maps. 
How difficult would it be to implement this in GEOS, and, possibly, to 
build a hook for it in PostGIS?
