Colouring London
How many buildings are there in London? What are their characteristics? Where are they located and how do they contribute to the city? How adaptable are they? How long will they last, and what are the environmental and socio-economic implications of demolition?
Colouring London is a web-based citizen social science project designed to help address these questions by crowdsourcing and visualising twelve categories of information on London’s buildings.
Structure
This repository will contain open-source code for the project which:
- stores building footprint polygons and source metadata
- allows site users to record building attribute data
- serves map tiles rendered from collected data
- allows site visitors to download the collected building attribute data
Building attribute data collected as part of the project will be made available for download under a liberal open data license (ODbL).

migrations) - Fill out details in
config.json(seeconfig.template.json) - Load buildings and geometries to database (see
etl) - Install app dependencies:
