Toronto Building Height
Interactive Toronto Height and Zoning By-law maps were created by combining datasets from the City of Toronto Open Data website. The interactive web maps are powered by Carto.
The building footprint, elevation and attribute data were sourced from the following datasets:
3D Massing: The 3D Massing datasets provides a spatial representation of building footprints and the building height (EleZ attribute). Additional attributes from the other datasets were joined to this layer using a spatial join.
Address Points: A spatial join was used to associate property addresses to the building footprints.
Zoning By-Law: A spatial join was used to associate a land use zone category to the building footprints.
The data and maps went through a number of drafts and experiments using Carto before creating the final 3D Zoning By-law map using Mapbox GL.
