Buildings from OpenStreetMap and Overture, stood at their mapped heights; the sun computed in your browser, every ten minutes. Trees, terrain and awnings are not in the model. Methods & sources

Sol for iPhone is coming soon. Its Shadow tab stands your own building on this board wherever you are, and a turn of the dial walks its shadow through the day.
How it knows.
The buildings
Every building within a few hundred metres, from Overture Maps’ buildings archive, built on OpenStreetMap, through Sol’s own tiles: the same the app’s Shadow tab stands on. A building stands at its surveyed height, else at 3.2 m a floor, else at what its kind usually stands.

The sun on a spot
The day is sampled every ten minutes. A sample counts when the sun stands more than a degree above the land, in front of the surface, and the line from the spot toward it passes no building. A spot on the ground is read at head height, 1.5 m.
What it leaves out
Trees, hills, awnings, balconies and anything not mapped as a building. Buildings past the board’s edge are not counted, and clear sky is assumed: this is the geometry of the light, not the weather.
Your own building, in your pocket.
