Improved conflation for MultiLineStrings and GeometryCollection #18

Closed rsavoye closed 5 days ago

rsavoye commented 1 week ago

The core conflation algorithm has been improved to test each segment in a MultiLineStrings and GeometryCollection for the distance and angle calculation, improving the results considerably. With this patch, the post conflation results look very good. They're suitable now for other people to work with if interested.

Also improvements to the contrib script that maintains the source data to allow updating a single state or national forest/park.

I'm going to self approve, as this greatly improves the conflation accuracy, and other work needs to build on this.
