I do want to ask paul if we can grab his example for the user guide.
As for solving your problem (ie data cleaning) there are a couple of approaches.
- The easiest is to "drop down" precision; and define a PrecisionModel that
uses less accuracy (say float if you are working in double) and call
makePrecise( coord ) on each. You can do that quickly using a coordinate
sequence to visit each point in a geometry. This has the effect of snapping
poins to a "grid"
- Failing that you can use the snapping code to try and snap lines together
(http://docs.geotools.org/latest/userguide/guide/library/jts/snap.html)
- Or just simplify the geoemtry prior to use (using a PrecisionModel to try and
snap the points to a grid basically)
