Isometric Toronto

Isometric Toronto 3D

The whole City of Toronto as a 3D model you can turn: every building the City has mapped, on the real ground, with its trees, streets, parks and the lake. Drag to pan, right-drag or twist two fingers to turn, scroll or pinch to zoom, and get close: the buildings fill in as you go.

Keys: ← ↑ → ↓ pan, + − zoom, Q E turn, N north up, 0 the whole City.

A companion to Isometric Toronto, the illustrated map. Made by John Fewell.

How it's made

The buildings are the City of Toronto's 3D Massing, each drawn from its footprint and heights with a facade and roof picked to suit it. They stand on the ground from the Ontario lidar terrain model, with streets, parks, water and the airfield from OpenStreetMap, and trees found in the lidar. The CN Tower is a modelled landmark. Far away the buildings are simplified; close up each one loads in full. The data and much of the engine come from Slop Toronto.
