How light & shadow move across your plot

A shadow study for one plot, across a whole year. Drag the time slider for any moment; switch to Year to see where the sun actually lands, hour-totalled. Drag the buildings and trees to match your surroundings, or add your own.

What to notice as you scrub the year

    Location

    Sun angles are computed for the coordinates in the top bar. Paste them from Google Maps, or tap the pin to use your device.

    How to get your coordinates from Google Maps
    • Desktop: right-click your exact spot on the map. The very first row of the menu is the latitude, longitude (e.g. 19.0621, 72.8834) — click it to copy, then paste into the lat, lon box up top.
    • Phone / tablet: press and hold on your spot until a red pin drops. The coordinates appear in the search bar at the top (or the info card at the bottom) — tap them to copy, then paste.
    • Aim for the centre of your plot, and zoom in first so the pin lands accurately.

    Your plot & surroundings

    The pieces on the map are an example — a plot with neighbours on three sides, a low front wall, and a tree. Drag them, resize them, or delete and replace with your real layout. Heights are what matter most for shadows.

    Height
    Sun positions computed with the NOAA solar algorithm for this exact latitude/longitude. Shadows assume flat ground and the heights you set. A modelling aid, not a survey.
