I recon that for long island, splitting the unsimplified edge on
the closest point to the island might make it simplifiable.
Probably a single point is not enough for the Brazil case, but
a recursive approach would find next closest point and succeed.
Just wanted to get back on this as I think it's the logical continuation
of the SimplifyEdgeGeom approach. On "collision" exception you would
basically have the information about the edge being simplified (let's call
it "E") _and_ the colliding obstacle (let's call it "O", be it a node or
edge).
You would then compute the closest point of "O" onto "E" and split "E"
by that point. Then re-run on each of the sub-edges "E1" and "E2" resulting
from the split.
Re-joining the sub-edges after simplification may or may not be something
you'll want to do within the same function.
I'll love to know if such approach would have all the required lower-level
editing functions in place.
Hello Sandro,
Just want to let you know that I did not have the opportunity to
proceed with this. Extremely busy with other work. Sorry about that. I
hope to be able to look into topology again a few weeks from now.
Best regards,
Michiel.
P.S. The reason that my function only selects faces with a single
edge, is it aims to delete islands, completely surrounded by sea.
Small coastal islands practically always consist of only one edge.
