CURRENT USE

[polly64]

Live land use task list

Priority asks:

1. [x] Upload OS sites data (Dining)
2. [x] Add dwellings as default for all buildings (in progress, eta ~8pm)
3. [ ] Add world 'default' after 'Dwellings' on the drop down
4. [x] Add a note or hover saying '93% of properties in UK are dwellings so we have created this as the default colour. Can you help us by colouring in all non-residential and mixed use buildings?'
5. [x] Add 'Vacant and derelict' back onto key
6. [x] Check key colours match (e.g transport)
7. [x] Get copy tool operational
8. [ ] Make everything in drop down alphabetical
9. [ ] Change text in land use box to read' start typing to view options' as we need an instruction here to get them to put something inl
10. [x] Remove dropdown entries for groups that aren't relevant to buildings e.g forest, minerals etc . But we need to keep agriculture as this includes 'vets'.
11. [ ] Make checking NLUD look up tables easier or possibly add class drop down
12. [x] On the blue notice can this read ' Land use order, shown below, is automatically derived from the land use groups' i.e. adding 'shown below' i know it sounds obvious but think no harm in making super clear as the word 'order' is not in common use.
13. [x] Add word 'pure' to retail on key- so says Retail (pure)
14. [x] Add Agriculture back
15. [ ] Make line between buildings more visible as can't see divisions on land use
16. [ ] Change blue colour on dwellings to have some translucency so we can read text underneath when doing first draft (Maciek let's discuss if you don't think good idea)l
17. [x] Add U030 Minerals U031 Mineral workings and quarries - ( have just found a couple of quarries right on outskirts)
18. [x] Add new text on key to Retail - Remove word 'pure' and replace with Retail followed by smaller letters (pure/ incl. services)' as petrol stations. mechanics, printing services etc are also classified as retail.
19. [ ] Link in NLUD excel table
20. [x] Change Agriculture colour to hex fa667d
21. [ ] Add multiple orders for mixed use

Non priority tasks

1. [ ] Add 'Dwelling outbuilding' option on dropdown (not priority see discussion below)
2. [ ] Add 1786 road vectorised network data as optional layer (not priority - by September 2020)

Discussion points specific to Land Use :

• Possibly merge with TYPE category colouring-cities/colouring-core#567 so that we have a new sub cat for 'original use/use when first built'.PH to look into

• Decide if we want to change name from Landuse to Building use. PH to assess

• Continue to look into ways of making planning classes easier to find and address problems of descriptions e.g that shops include services such as mechanics, petrol stations etc. Should we for example add in brackets and italics after 'Shops (incl. services)?

• Problem with fact that business parks include manufacturing, offices, storage, wholesale distribution, retail services such as car repair can often housed in the same building modern warehouse type building -and that these uses can easily change and likely to with COVID. Often no label on aerial image and can't get to street view as now road. means though I know is one of uses above actually have to leave with no colour. maybe only option but would be good to discuss.

• We need to continue to discuss lack of consistency of land use classes used in UK with MHCLG as NLUD also not perfect and be aware in future classification system may need to be changed if new harmonised system introduced.

• Domestic outbuildings Any thoughts on domestic outbuildings? A few comments from my end. Feels we should differentiate these from dwellings as so many of them and are not liveable in or should we? Gardens are hugely important areas for discussion re sustainable development - should incremental development be encouraged; to what extent should gardens be retained etc, what is amount of garden area lost each year to development, how does this impact on urban heat etc. Steve Evans has also just fed back said interesting to pick these up

  1. No garden building/dwelling outhouse option on NLUD. Closest most suitable is ' Storage' but this comes under the Business and Industry Order.
  2. I started filling them in as storage to see what it looked like in a different - firstly felt very intrusive so coloured them back to dwelling - also they might not be storage might be garden office etc.
  3. Feel we could justifiably do it as 'dwelling outbuildings' as a subsection of dwellings but not sure how this would work in dropdowns- could we add ' domestic outbuildings' as a new group and attach to dwelling order?
  4. Feel would be good to try to pick these up in a single go - we could write an algorithm e.g select all polygons under x and over x (to avoid masts etc) that are detached. Would need to clean out garages but these are v regular and think you could do simple algorithm for this too, then would need third layer of cleaning but doable - can ask Flora

@polly64 a couple things to clarify:

• Make checking NLUD look up tables easier - what would that be specifically?
• making edit history more visible - is this equivalent to the "last edited by" feature?

[polly64]

h @mz8i ok I think the making accessing to NLUD is ok for moment- this a liked to a bigger issue of whether we add in a class category - but not a top priority

Making edit history was something Dom brought up- ideally we are looking to have 'a 'date last edited' visible on on this - and really all categories- if this is easy to do then great but if time consuming would park as we have the history button which can be used if needed

@polly64 can we just confirm which table do you need for the Land Use class list? Is it the index from pages 43-54 in https://assets.publishing.service.gov.uk/government/uploads/system/uploads/attachment_data/file/11493/144275.pdf ?

[mz8i]

@polly64 for the land use group dropdown, the current placeholder text says "Type new land use group here". When the user clicks on the box, it will automatically show a list of all options, which will then be narrowed down if the user types anything. Will changing it to "Start typing to view options" give the user more information?

[polly64]

Yes that's the one page 43-54

Re text can u just add ' start typing .. rather than type as makes more active - just speaking to dinding but will look at after this call think there might have been another issue

[polly64]

@mz8i yes text is actually fine . and yes it's 43-54

[polly64]

@mz8i have struck through translucency on list as realised that when we improve lines between buildings it will mean that its addresses the problem. Also have added the 1786 network to list but this is just by Sep 2020 ie by the time next grant goes in as this is a real game changer in understanding what the platform can do- and in terms of value of historical data. Once you overlay this you instantly understand how the entire retail (and in fact entire non-domestic) system in London works.

[mz8i]

@polly64 according to https://assets.publishing.service.gov.uk/government/uploads/system/uploads/attachment_data/file/11493/144275.pdf (page 38) I think domestic outbuildings should be classified under Dwellings - the description says "Houses and flats for individuals and families living as a single household, including adjoining garages, gardens, non-thoroughfare service and distribution roads and pathways" - this does not mention "domestic outbuildings" specifically, but as it mentions garages (so garages should not be under Vehicle Storage but rather under Dwellings) then I think it's the same for all other types of structures that are related to, and situated next to, residential buildings

[polly64]

@tomalrussell @mz8i @dominijk Maciek has transferred NLUD classes into excel sheet attached. I am going to also add common classes are I think missing in a way that shows these are not NLUD but directs people for the moment to an NLUD class This will allow us to gradually build a more relevant and less biased land use classification

We will also need to work out a way people can easily add suggestions but that can be left for the UKRI citizen science application

@mz8i Hi maciek Dropdown order for land use group attached

NLUD order dropdown.xlsx

[polly64]

@mz8i I think - adding to your thoughts on acccuracy- we need to make it so that when u verify a domestic building to colour changes from dark blue to light. Otherwise we can't differentiate between checked and unchecked. then need add this to key as well- how difficult would this be to do?- think quite important as agree we are open to criticism here- if we had this i could actually start doing this in evenings as it's quite quick by eye but can i copy and paste verify?

[mz8i]

@polly64 I would advise against incorporating such complex logic into the raster tile layer and in the current set up I would leave the tiled map to display a single colour scale, as generating new tile layers for each such combination would be quite resource intensive.

But maybe what we could try is display the usual land use colour scale on the map, but then use the Open TOID coordinates to display a pin layer over that, and only display pins on buildings that should be verified? Let's work on the import of those coordinates first, and then we can test such mechanisms.

[polly64]

@mz8i sure thing sound v interesting
