Hi Jukka, all, Interesting idea. Not an easy task, but now, most of the code exists. Not sure what would be the benefit compared to digitizing roads noding them in one step, then creating your polygons.
One difficulty would be to define options (all options in the new noder plugin would also make sense in an interactive context) Another difficulty is to index features to find candidates to noding efficiently, as stefan told In order to re-use what has been done without duplicating too much, I think I would proceed the following way : - use existing digitizing tool and extend them (ex. double click creates the line, double click + key 'n' creates the line and node it) - use existing plugin options panel to read the user preference (eventually duplicate the panel to have it in the options dialog box) - try without indexing Michaël PS : I updated the documentation about noder https://sourceforge.net/projects/jump-pilot/files/Documentation/PlugIn%20Documentation/Noder%20PlugIn/ Le 02/01/2012 18:13, Stefan Steiniger a écrit : >>> but a question.. how do you deal with layers that have lots of objects? >>> (OJ would be in-responsive) >> how is the noder plugin dealing with it? is it capable to find overlaying >> geometries (in a performant manner) or are they manually selected beforehand? > 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 > > ------------------------------------------------------------------------------ > Ridiculously easy VDI.
