Behind the scene

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

The amount of water shown in the Los Angeles River channel is an illustrative model setting. It does not represent a measured river level or a flood forecast. 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 source package can also be downloaded there.
