The noding is done on a whole layer (FeatureCollection). so nothing is left out - as far as I know (Michael may know more on Topology operations based on JTS). If one would use an index to speed things up, one would have the issue that merging/updating of the dataset needs to appear, which will be tricky. stefan |
