How Berlin Sun Seeker Works

Every night, Berlin Sun Seeker calculates shadow patterns for the next 14 days using Berlin's official 3D building data (LoD2 city model) from the Berlin Senate and the Baumkataster, the city's comprehensive tree registry with species, height, and crown data for over 434,000 trees. Our shadow engine traces the sun's path across 550,000 buildings and projects shadows onto more than 11,000 outdoor venues, checking each venue every five minutes from sunrise to sunset. The result is a live map where gold markers show which terraces are in sunlight right now. No guesswork, just geometry and open data.

Cafés, Biergärten, and More

Berlin Sun Seeker tracks sunshine for every type of outdoor spot in the city: café terraces, bars with afternoon sun, restaurant patios catching the last rays, biergartens, pubs, Spätis with outdoor seating, ice cream shops, marketplaces, playgrounds, dog parks, community gardens, swimming pools, boules courts, picnic areas, and viewpoints. If it's mapped on OpenStreetMap, we're tracking the sun for it.

All 12 Berlin Districts

Berlin Sun Seeker covers outdoor seating across every Berlin district: Mitte, Friedrichshain-Kreuzberg, Pankow, Charlottenburg-Wilmersdorf, Spandau, Steglitz-Zehlendorf, Tempelhof-Schöneberg, Neukölln, Treptow-Köpenick, Marzahn-Hellersdorf, Lichtenberg, and Reinickendorf. From the café scene around Kastanienallee in Prenzlauer Berg to the lakeside beer gardens of Köpenick, our shadow analysis covers the full breadth of the city. Berlin Sun Seeker is a community project built on Berlin's own open data, a gift back to a city that publishes its datasets for everyone. All data is freely available under open licenses.
