[Gvsig_english] Question about Geoprocess toolbox: Topology errors correction in line vector layer

[Alvaro Zabala]

What geoprocess are you running?

gvSIG uses JTS to do primitive topology and computational geometry
operations.

JTS data model allows self-intersecting polylines, so its not a problem.
Self-intersecting polygons are not allowed, so geoprocesses ignores these
ocurrences.

In current gvSIG versions, overlay geoprocesses only works with polygon
layers. In next gvSIG version, overlay geoprocesses also works with polygon
layers.

Finally, this year (second or third quarter) a new gvsig' s topology
extension will be released. This extension allows to ensure correctness of
spatial data by applying topology rules constraints.

Best regards.
