Some things I'd love to see: - a difference metric between this coverage and the actual map (and country breakdown of same) - a weighted version ([1]) with weights chosen to optimize the above distance metric. The latter is in itself is a fun math problem -- the gradient on such an objective clearly exists (and the numerical gradient is fairly cheap). But can you prove anything about its structure? Is there a closed form that could be derived from the map information? [1] https://en.wikipedia.org/wiki/Weighted_Voronoi_diagram https://en.wikipedia.org/wiki/Weighted_Voronoi_diagram
