This fixes a bug caused by the recent react-leaflet update, where the URL prop of the TileLayer component is no longer mutable in v3, so map layers which depended on the layer reloading upon a URL change, needed to be adjusted. The solution was to add appropriate key props to the layers, to force recreating the layers. To simplify the management of layer reloading and to ensure some base layers don't re-appear above higher layers, the layer organisation was reworked using custom leaflet Panes. The file organisation was also changed to separate the logic for the different layers into their own components, rather than having everything in map.tsx |

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).
Setup and run
- Provision database (see
migrations) - Load buildings and geometries to database (see
etl) - Install app dependencies:
cd app && npm i - Run tests:
npm test - Run app:
npm start
In development, run with environment variables:
APP_COOKIE_SECRET=test_secret \
PGHOST=localhost \
PGUSER=dbuser \
PGDATABASE=dbname \
PGPASSWORD=dbpassword \
PGPORT=5432 \
TILECACHE_PATH=/path/to/tilecache/directory \
npm start
Acknowledgements
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.
