Initially we set out to collect and share numerical and categorical data
|
2018-04-30 14:45:40 -04:00
|
|
|
|
relating to the age and land use of buildings for research into the built environment and
|
|
|
|
|
|
demolition, but we soon realised that the opportunity existed to capture many
|
2018-04-15 15:05:22 -04:00
|
|
|
|
more types of data for use in all sorts of areas: from local history and
|
|
|
|
|
|
heritage to building conservation, sustainable urban planning, architecture and
|
|
|
|
|
|
the built environment.

We have some ideas, but we also hope to be surprised! Our main task is to
|
|
|
|
|
|
enable the collection, collation, visualisation and dissemination of the data.
|
|
|
|
|
|
We are very excited to see how they are used. To help stimulate discussion and
|
|
|
|
|
|
ideas we will include a data showcase which will allow anyone to share examples
|
|
|
|
|
|
of how they use Colouring London data, and to provide examples of how similar
|
|
|
|
|
|
datasets are being used elsewhere in the UK and around the world.

No, not for London as a whole. The Valuation Office Agency holds the most
|
|
|
|
|
|
comprehensive records for tax purposes, but these are restricted at the building
|
|
|
|
|
|
level, even for research within academia.

Our main focus is to collect data for modelling and statistical analysis, where
|
|
|
|
|
|
numerical and categorical data tends to be most useful. However, we will
|
|
|
|
|
|
collect links to other sites where text based information on a building can be
|
|
|
|
|
|
created and shared. The <a href="http://alpha.layersoflondon.org/"

|

|
and the Bartlett Centre for Advanced Spatial Analysis (CASA) both have an
|
|
|
|
|
|
interest in text (and audio and photographs). We are working in close
|
|
|
|
|
|
collaboration with both projects.

We have had conversations with many different groups, from academics and
|
|
|
|
|
|
teachers to community groups and built environment professionals, and found
|
|
|
|
|
|
many overlaps. We have limited ourselves to 12 main categories to keep things
|
|
|
|
|
|
simple, within which there are around thirty sub-categories. The prototype
|
|
|
|
|
|
testing period will allow us to see whether there are any key categories
|
|
|
|
|
|
missing—feedback is welcome.

Our intention is to cultivate a community which can handle occasional
|
|
|
|
|
|
disruption, along the lines of other collaborative online projects. The site
|
|
|
|
|
|
will allow anyone to upload and edit data as they like and to go back and forth
|
|
|
|
|
|
over the details if necessary. Quantitative data on the building stock is, we
|
|
|
|
|
|
hope, not too controversial, other than perhaps for large developments. The
|
|
|
|
|
|
locations of utilities’ may be sensitive, but this is not within the main
|
|
|
|
|
|
scope of our data collection. For the ‘Like me’ category, users
|
|
|
|
|
|
will have only one vote per building.

We recognise the importance of this but in the first instance we will only
|
|
|
|
|
|
gather data on the buildings themselves. We will however include a sub-category
|
|
|
|
|
|
which records a building's position, i.e. mid-terrace, end-of-terrace,
|
|
|
|
|
|
semi-detached or detached.

We rely on Ordnance Survey MasterMap for our building outlines, so if these are
|
|
|
|
|
|
not subdivided, we will need to attach extra data to the single outline, or
|
|
|
|
|
|
else consider altering the outlines manually. Some buildings have the opposite
|
|
|
|
|
|
problem, where there are multiple polygons for a single building. For example
|
|
|
|
|
|
some post-war estates have each of the balconies drawn separately. Our hope is
|
|
|
|
|
|
that the project will stimulate discussion with Ordnance Survey regarding a
|
|
|
|
|
|
more user friendly open version of the building outlines.

Yes, in principal. We hope that Colouring London will act as a proof of
|
|
|
|
|
|
concept. We rely on a sufficient set of building outlines to provide the basis
|
|
|
|
|
|
for all the building attribute data that we collect—for London, Ordnance
|
|
|
|
|
|
Survey and the Greater London Authority have supported us by providing
|
|
|
|
|
|
the MasterMap building outlines.

Yes, we had a discussion with OpenStreetMap contributors at an international

|
mapping conference in Leuven last year and would very much like the

|
|
|
|
|
OpenStreetMap community to become involved in the project. We hope that by
|
|
|
|
|
|
generating data of relevance to local areas we will also stimulate increased
|
|
|
|
|
|
interest in OpenStreetMap and in collecting building outline polygons as open
|
|
|
|
|
|
data.

Yes, all the building attributes which we collect will be available under an
|
|
|
|
|
|
open data license. However, we are limited by Ordnance Survey data licensing
|
|
|
|
|
|
and are not currently able to provide building outlines or geographical
|
|
|
|
|
|
coordinates. We will provide sufficient data for MasterMap users to link
|
|
|
|
|
|
building attributes to their own copies of the polygons.

|
|
|

step towards providing location details. We will also look into the

possibility of creating and sharing geographical coordinates for our

dataset as open data, as suggested by a contributor, in collaboration with the
