Are there any OpenJump tools for conflating (matching) two layers of point (node) data?
I'm particularly interested in using such a tool to sync data with OpenStreetMap, where I've created a wiki page on the subject of conflation. That page links to some university research projects on the conflation of vector datasets using OpenJUMP, however they don't share their work.
I know algorithmically this task shouldn't be that difficult especially compared to handling generic vectors, as it would simply use distance and similar properties along with some math, however I suppose I'm more interested in a graphical interface implemented in open source software.
I think it might be useful to say what use cases I'd be interested in using this tool for.
- Syncing Virginia interstate exit data from VDOT with OSM
- Syncing GNIS feature points with OSM
After an extension to conflate polygons (using their centroids), the tool could also be used for:
- Transferring properties (tags, attributes) between nodes representing a house along with addressing data to a polygon (area, closed way) of the actual building
I'm sure there are many other possibilities, but these are the few I'm planning to use it for.
