Finds the shadiest walking route between two points in Valencia — including which side of the street to walk on. Building heights come from the Spanish Cadastre, streets from OpenStreetMap, both baked into one precomputed file. Shadows and routing run entirely in your browser. No API keys, no server.

  1. Click the map to drop A (start), then B (end). Markers are draggable.
  2. Press Find shady route.
