Behind the scene

Weather data comes via Open-Meteo. Sun and moon positions are calculated for San Francisco and the selected time. People, traffic and palms are animated; their movement responds to the weather.

Water levels and fog are illustrative model settings, not local measurements or flood forecasts. Official warnings are available from the National Weather Service.

Building footprints and terrain are prepared for the city model, missing heights are supplemented and details are simplified. Open Licence for the geodata sources, processing notes and terms of use. The required derived geodata is available free of charge on request through that page.
