Initially we set out just to capture and release numerical data relating to age
|
|
|
|
|
|
and land use relevant to energy and demolition related research within
|
|
|
|
|
|
academia, but we soon realised that the opportunity existed to capture many
|
|
|
|
|
|
more types of data for use in multiple applications.

Our main job is to facilitate the collection, collation, visualisation and
|
|
|
|
|
|
dissemination of the data. We are very excited to see how they are used. To
|
|
|
|
|
|
help simulate discussion and ideas we are including a data showcase which will
|
|
|
|
|
|
allow anyone to upload examples of how they are using Colouring London data, or
|
|
|
|
|
|
how the same data categories are being used in other areas of the world.

Not for London as a whole. The Valuation Office Agency holds the most
|
|
|
|
|
|
comprehensive records for tax purposes, but these are restricted at building
|
|
|
|
|
|
level, even to academia.

Our remit is to collect numerical data for statistical analysis. However we
|
|
|
|
|
|
will also include an area where a link can be added to take you to any web site
|
|
|
|
|
|
page/pages where text based information on the building can be accessed. IHS’s
|
|
|
|
|
|
‘Layers of London’ project http://alpha.layersoflondon.org/ and The Survey of
|
|
|
|
|
|
London/CASA’s Whitechapel project https://surveyoflondon.org/map/. We are
|

|
|
|
|
working closely with both HIS and The Survey.

We asked many groups, ranging 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 thity sub categories. The prototype testing period will allow us to see
|
|
|
|
|
|
whether there are any key categories missing.

Quantitative data on the building stock probably/hopefully not that
|
|
|
|
|
|
controversial other than for large developments. Utilities’ location may be
|
|
|
|
|
|
sensitive. We think unlikely to occur other than perhaps where issues surround
|
|
|
|
|
|
a particular development. Here the system allows both developers and
|
|
|
|
|
|
communities to upload and edit as they like and battle it out. For ‘Like me’,
|
|
|
|
|
|
users have to login and have only one vote per building.

Like Wikipedia you will have to keep re-editing, however edit histories will

|
|

help users see where data comes from ie if it is uploaded by a specialist body.

We recognise importance of this but we are only, in the first instance
|
|
|
|
|
|
gathering data on buildings, themselves. We do however include information
|
|
|
|
|
|
building position ie mid terrace, end of terrace, semi-detached and detached

We can record multiple uses but are reliant on OSMM polygons so if not
|
|
|
|
|
|
subdivided (as for UCL building) we have to either do this manually or group
|
|
|
|
|
|
all uses under a single polygons. Our hope is that the project will stimulate
|
|
|
|
|
|
discussion with OS regarding a more user friendly open version of the building
|
|
|
|
|
|
footprints. Post war estates for examples have separate polygons for balconies
|
|
|
|
|
|
etc which is not ideal.

Yes if OS permits use of polygons. Colouring London will act as a proof of
|
|
|
|
|
|
concept.

We had a discussion with OSM at an international mapping conference in Leuven
|
|
|
|
|
|
last year and would very much like the OSM community to become involved
|
|
|
|
|
|
project. We hope that by generating data of relevance to local areas we will
|
|
|
|
|
|
also stimulate an increase interest in OSM and in building polygon generation.

This is the main reason why address detail collection is so important, is so
|
|
|
|
|
|
that we can offer some spatial reference within the open tables. We will also
|
|
|
|
|
|
be asking the OSM community if, as suggested by a contributor, it can help
|
|
|
|
|
|
upload WGS84 coordinates.
