Matt Parker of Stand-up Maths asks whether a country's reported land area accounts for hills and mountains, working through how surface area depends on the resolution of elevation data. It follows up on a question from a viewer and work by researchers who measured it.
HN 推薦的原因： HN recommends it in map projection and coastline threads as a fun look at how measurement choices change area figures.
