'Age and History' Renaming and merging of Age and Dynamics main categories

[polly64]

Planned co-working with IOER/Turing on this section

The plan is to merge 'Age' and 'Dynamics' and rename 'Age & History'. This will better signpost the section dealing with long-term dynamics for historians and heritage specialists and free up a category to enable expansion of 'Sustainability' on the 12 colour category grid.

Age & History capture spatial data at building level relating to the following:

1. • Current building age (core and historical extensions)- numerical data input
2. • Building survival rates - using historical raster maps + current vectorised footprints
3. • Building lifespans for demolished buildings (for individual buildings and typologies) - numerical data input
4. • Site histories - numerical data input
5. • Historical information on demolished buildings - vectorised historical footprints
6. • Historical sources/links- urls

1. - Current building age (core and historical extensions)- numerical data input
IMPLEMENTED: See: https://colouringlondon.org/view/age/2407428
TO BE IMPLEMENTED:

• Cladding date (if different from core)
• Extension dates add plus sign to add info and sources for each
• Retrofit date -how should this be linked to sustainability section? explain what type
  Verification buttons for each and sources required

2. - Building survival rates - using historical raster maps + current vectorised footprints
IMPLEMENTED: 1890s London example integrated into mapping interface with overlay of current building footprints.
TO BE IMPLEMENTED: Click on any footprint and add info on closeness of match to infer persistence/resilience of form. Select 1 option for colouring - Google Streetview may also be helpful i assessing whether original building survives :.
Colour 1 for buildings where the current structure/footprint and the historical footprint is identical or almost identical to the original;
Colour 2 for buildings where core building still exists but significant alterations have occurred
Colour 3 where the structure has been completely replaced/demolished.
Data are expected to be crowdsourced though automated techniques will be introduced once methods for vectorising historical footprints have been advanced,

5. 5. - Building lifespans for demolished buildings (for individual buildings and typologies) - numerical data input
6. 7. - Site histories - numerical data input
7. 9. - Historical information on demolished buildings - vectorised historical footprints
8. 11. - Historical sources/links- urls

with current footprints, but we would still need specialist/local contributors to confirm whether the building was just a new reconstruction on same site or the original as this obviously can't always be seen from the plan.

We also don't have vectorised footprints to work with yet Once we have a sample we can demo how vectorised historical footprints can be used to crowdsource information on the 1890 structure itself- e.g. land use at the time (so we can begin to track patterns of land use change over 130 years) and links to archive data on history of occupiers etc. as well as size, materials and typology for examples where buildings have been demolished (for extant buildings this information will be held under our main categories of 'Size', 'Typology' and 'Construction')
