How many buildings are there in a city? 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 Cities is a web-based citizen social science project designed to help address these questions by crowdsourcing and visualising twelve categories of information on the buildings in our cities.
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).
If you are working with us as part of this GitHub organisation, then a repository and team may already have been set up for you. If you are already using the repository and want to add a new project, perhaps because you are expanding to additional cities, then please following these instructions to create a Fork of the core repository: working-with-colouring-core.
You can customise the Colouring Cities application by changing the values in the following file:
app/src/cc-config.json
For more information on the config system, see configuring-colouring-cities.
You can try out the Colouring Cities application by setting up your own development environment, which includes the option to load test data from OpenStreetMaps (OSM). See setup-dev-environment.

We also have documentation on setting up a production environment here: setup-production-environment.

Note: There are additional useful documentation in the CCRP Technical Manual.
If you are having problems with the application, first look here: troubleshooting to see if there is a solution for your problem. (Also, please consider updating this document if you encounter and problems and manage to solve them!)
Colouring London was set up at the Centre for Advanced Spatial Analysis (CASA), University College London and is now based at The Alan Turing Institute. Ordnance Survey is providing building footprints required to collect the data, facilitated by the Greater London Authority (GLA), and giving access to its API and technical support.
