[talk-ph] better ways to coordinate coastline mapping?

I agree, but can we keep the sawtooth webmap running for a few more
weeks/months?

Another thing, I am thinking is a script to report whether an island
node is enclosed by a coastline way.

A point-in-polygon in GIS-speak.

This should help us identify and map the smaller islands.

Coders and other ideas welcome.
