Every kind of place, in its own style.

Landmarks, old houses, new towers, a forested hill and a river with its bridges: the map draws each from the city's own records. Landmarks and land are in the Model look, buildings in Clay. In dark mode the same places are at dusk with the lamps lit.

Made by hand. Grown by code.

Nothing on the map is a stock model. Trees are grown from the species in the city's inventory, you are a pearl that catches the sky, and every event is a prism that splits the light.

Six tree shapes in a row on a lawn: a round crown in ochre, a broad blossom crown in orange, a tall flame crown in red, a tiered conifer in green, a narrow column in gold, and a weeping crown in olive.
The six tree shapes charper grows from the city's tree inventory and canopy data: round, blossom, flame, conifer, column and weeping, in their autumn colours. Lined up on a lawn for this page; on the map they stand where the real trees do.
Close up, an iridescent pearl hovers over a lawn beside a house: its rim shifts through green, gold, rose and violet, with a soft highlight from the sky.
You, on your own map: an iridescent pearl, shown at your blurred spot, never your door. Everyone else is a face in a ring, and only where enough people share a spot for everyone there.
Close up on the Mount Tabor miniature: flocked firs and yellowing maples around the amphitheatre's clearing, where a small glass prism throws a rainbow onto the grass.
A party tonight: a glass prism over the place, throwing its rainbow on the grass. A render made from the charper map.
