Each dot is a map. The light band after 1st place is the margin: only whoever passes it takes the top spot.

How the ranking works

• Open working. Score = 100 × sharpness^0.35 × depth^0.25 × palette^0.40. Same input, same score.
• Defended spot. 1st place only changes when the challenger has a margin of 5 points or more.
• No one else’s image. Thumbnail only with the author’s permission. Without it, the drawing next to the map is a glyph generated from the data.
• No sign-up. No account, e-mail or tracking to see or compare.
