GoKawiilBorderline game data reveals 37,500 hand-drawn national border maps
An online geography game called Borderline has compiled roughly 37,500 crowd-sourced drawings of country borders and coastlines, aggregating them into a visual map that overlays every submitted outline against the real one. The project breaks results down by country, drawing type (land border, coastline, or daily challenge round), and includes median accuracy scores and error rates for each nation.
