A Blinking Map of the World’s Lighthouses

posted by Jason Kottke   May 04, 2021

a small section of a world lighthouse map showing the location of lighthouses in the Mediterranean Sea

Courtesy of Geodienst, this is a map of the world’s lighthouses. Where the data is available (and you can see it’s quite sparse for some areas of the world), the map shows the location, color, range, and flashing frequency/pattern of each lighthouse. The color and flashing pattern of a lighthouse is called the characteristic. Each lighthouse has a different characteristic so that mariners can tell them apart and to indicate different water areas.
