    For those who don’t know already, this is called a Voronoi diagram.

      I think I’m too stupid to understand this. How are they straight lines and not at a diameter / in a circle from any given point? It seems… wrong.

          Oh! It totally does. I guess I’ve just never had to apply distances in such a way that they’d butt up against one another to become what looks like basic geometry.

          Thanks!

          I assume part of the confusuion is that the earth is not flat. If one would create a Voronoi diagram on the surface of a globe, the resulting borders would still be straight lines, but, when projected, it depends on the projection, whether they remain straight.

          The creator probably started with a Mercator projected map of Europe and then calculated the distance between any point on the map and all capitals. The distance on two points on the spere, however, cannot be obtained by counting the distance in h/v pixels on the map and applying Pythagoras, as Mercator projection exaggerates horizontal, east-west, distances. So one needs to map the pixel coordinates back onto the sphere and calculate the distances there.

          It’s definitely a nice map though.

            I’ve tried to demonstrate it here. You end up with straight lines because it’s always a middle point so it doesn’t curve one way or another between the two points.

            If the circles had a set radius then you’d have empty space and more circley-looking spots. But since they basically expand until there’s a middle point you’ll have these straight lines.

            Draw it, then consider where the exact middle point would be. Now do the whole line between them. I think that’s the best way to figure it out.

    On this map, you can see why Denmark’s capital is Copenhagen. When Denmark controlled Scania and Schleswig-Holstein, it was much more centrally located than today. The borders of Denmark in this map correspond roughly to the borders before the Treaty of Roskilde.

            Depends, when actually speaking Swedish only with Scanian accent, they are ok to understand, but when switching to Scanian – impossible, but in a different way than the Danes.

        Scotland is one of the four countries comprising The United Kingdom of Great Britain and Northern Ireland. The others are England, Wales and Northern Ireland. Scotland’s capital is Edinburgh.

          I fully support Scotland independence, however at this time it is a constituent country rather than a country, there is a slight distinction.

      I don’t know how NaytaData made it, but if I were doing it, I would do something like this:

      • start with a “blank” un-coloured map of coastline and country borders
      • put all the “capital” cities on the map
      • make a temporary grid of points over the map and find the closest city for each point
      • paint the map based on those temporary grid points

      I would use a computer but the same steps would work with paper & pen.

        If the OP is using GIS, it can be even easier.

        Your first two steps are spot on, but then step three could simply be to add a large buffer for each capital and use some and/or/nor/xor (I’d have to look up to be certain) rules to have the buffer zones not overlap, but end where touching. Apply a color scheme and you’re in business.
