WHY DO WE NEED THE DATA?
For Colouring London to be able to map the data you donate, and for you to be able see your building, or buildings, colour, we have to be able to access up-to-date information on the location and 'footprint' of every building in London.
These footprints act as mini filing cabinets, storing, locating and visualising
contributed data. Permission has been given by Ordnance Survey, to UCL, to use OSMasterMap footprints (OSMM) for London for these specific purposes. A separate agreement has also had to be set up, under The Greater London Authority's OS licence, to allow UCL to visualise OSMM data.
By October 2019, as well as being able to upload and view mapped data on the Colouring London platform, you will also be able to bulk download data. Current OS copyright restrictions however prevent us releasing location data and footprint geometries within our downloadable building attribute tables. It is currently unclear as to when OSMM will be fully opened up. In the meantime will be looking to link our data to Open Street Map addresses and centroid coordinates. We would be helpful for any help in this area. This will allow everyone (other than just universities, local authorities and others holding an OS licence) to download Colouring London data for use OSM, or to map it in other ways. The greater the number of location categories filled, the darker the building becomes, so you can easily see, where more data are required.
Until OSMM footprint data are fully opened up by the OS and the Treasury, we will continue to collecting address and coordinate information.
TYPES & TIPS
Colouring London is an open data platform and we can only accept data from unrestricted sources. Just use first-hand knowledge of the building wherever possible, or check your source is open and free for third party use.
OPEN LOCATION DATA
Colouring London would not be possible without the pioneering work of OpenStreetMap, The Open Data Institute, and others working in the open data movement. Following pressure over a period of many years, in 2017 the UK
Treasury announced that, owing to the potential significance of OS MasterMap to the UK economy, the dataset would begin to be opened up for public use. This would bring the UK into line with many countries that have already released national footprint data. Updates on OSMM release will be provided on this page.
UCL's collaboration with Ordnance Survey and the GLA on Colouring London, enables the platform to demonstrate how the release of comprehensive, updated, national mapping agency data at building level, for the country as a whole,will play a crucial role in assisting UK cities to meet ever more stringent emissions targets and sustainability goals. Furthermore to show how their release also have the capacity to unlock vast repositories of currently untapped knowledge about the city's buildings, able to be used for the common good.
