This is cool, but the shorelines are very low detail. A few towns in the UK are off in the sea, meanwhile Greenland and Northern Canada are hogging all the vertices. It looks as though the Mercator projection is already being accounted for in the detail level, but it would be good to deprioritize unpopulated areas.
I noticed that all of the New York City metropolitan area was replaced with a single angled line, cutting off several large islands supporting a few million in population.
I see this is improved in today's Nightly Demo link, but I still find the result too low fidelity.
