The "hotter" an area is, the higher the number of vessels that have crossed this point on the map. "Hotter" means more vessels were seen on that pixel:

  • blue = 1 - 2 vessels

  • cyan = 3 - 7 vessels

  • green = 8 - 20 vessels

  • yellow = 21 - 54 vessels

  • red = 55 - 148 vessels

  • magenta = 149 - 403 vessels

  • white = 404 - 1096 vessels
