Re: [Talk-GB] Tools to support solar panel mapping?

[Dan S]

Thanks Rob - we're using the FiT register already, but please note
that it doesn't disclose any official IDs (for privacy reasons, I
presume) so there's no "primary key", no definitive way to join the
dots e.g. across different versions of the FiT data. The REPD has a
primary key but it only covers larger installations. Most
installations, even if we can find metadata for them, we can't find an
official ID, AFAIK?

This is often wrong, as often the business does not occupy the whole

That's what I would have done. Curious as to why you think that is
inappropriate? Seems logical to me (addressing a letter would be Jewellery
company name, Wisdom Hall, Street, Town/City)

I'm almost certain I have pointed it out here already, but in case not: any
solar PV installation which is receiving a subsidy will be registered and
will therefore have an ID. Larger installations are installed in the
Renewable Obligations register. Smaller sites are in the Feed In Tariff
register.

The FiT register can be downloaded (in 3 parts) from:
https://www.ofgem.gov.uk/publications-and-updates/feed-tariff-installation-report-31-march-2019

The RO register can be obtained from the following site. You need to click

P.S. this is good for almost all sites built up to now. Going forward then

No; this is definitely Wisdom Hall. It's an early name, probably from 
before the JWs standardised on Kingdom Hall. Which is also probably 
also why the name has stuck beyond their use of the building.

Re: [Talk-GB] Tagging a named building now used for a different purpose

[Edward Catmur via Talk-GB]

The "building:name" tag would seem to be appropriate here.

Some examples:
https://www.openstreetmap.org/way/170028507
https://www.openstreetmap.org/way/85945126
https://www.openstreetmap.org/way/25911545

An alternative could be to have two objects: the building as a way, and the
tenant either as a node or as a (possibly fully) overlapping way sharing
nodes. I wouldn't go for this unless the building is sufficiently notable
e.g. having a Wikipedia article.

[Talk-GB] Tagging a named building now used for a different purpose

[Mark Goodge]

Looking for some advice...

There's a building in the town where I live that was originally 
constructed by the Jehovah's Witnesses and named, by them, "Wisdom 
Hall". It hasn't been used by the JWs now for several years, ever since 
they moved to a new location. The building is currently occupied by a 
jewellery company which uses it as their workshop.


However, the building is still known locally as "Wisdom hall", and that 
also still appears on the nameplate on the front of the building along 
with the current owner's trading name.


I've edited it to change it from a place of worship to a commercial 
building, as that's what it now is. (The previous tags were added in 
2015, well after it had ceased to be a place of worship, so I suspect 
the editor then was working from historic information).


However, I'm a bit unsure how best to tag it. Normally, commercial 
buildings have the owner's name as the value of the 'name' key. I could 
do that here, and then move the building name into the 'addr:housename' 
key, but that seems inappropriate. So I've left the building name as it 
was, which reflects current local usage.


But then, where does the current owner's name go? For now, I've put it 
into the 'operator' key. But I'm not really sure if that's the right 
place either.


This is the object in question:

Re: [Talk-GB] Tools to support solar panel mapping?

[SK53]

For solar panels as nodes I have been adding two things which could fulfil
these criteria:

   - A count of solar panel modules (the roughly 1.5 by 1 m individual
   panels) with generator:solar:modules.
   - Orientation (as generator:orientation) which can be in degrees or one
   of the 16 points of the compass.

The former is probably the most useful, as it is a good proxy for optimum
power capacity (roughly 320-370 W per module) and thus could be used
immediately in things like OpenInfraMap. Orientation is just one factor in
determining likely actual capacity which would be quite complex. It is
useful when an installation spreads over more than one part of the roof.

Re: [Talk-GB] Déjà vu

This is what I do with some kind of binary chop on dates (usually one has a
decent idea of when one thought it was on OSM),

I do have shops (& probably other stuff) extracted from an OSM History file
from the middle of last year, so could probably get more details that way
if required.

Re: [Talk-GB] Tools to support solar panel mapping?

[SK53]

A few thoughts:

   1. The technologies used by OpenSolarMap by Christian Quest and others
   Etalab.could be applied to OS OpenLocal buildings with a suitable training
   set. The original French data used high quality imagery classified by cloud
   sourcing as to roof orientation (flat, E-W or N-S) and then applied this to
   the rest of France.
   2. The available data on installations is via the FIT scheme itself, but
   is only broken down by postcode district which is really too large for
   basic searching. A breakdown by postcode sector would be much more helpful
   & not likely to infringe any privacy aspects. I put a list of the top 25
   districts on the wiki.
   3. Additional information which could be used to identify candidates
   are: road orientation (E-W being best); housing age (available for most but
   not all MSOAs IIRC) with Victorian & pre WWI semis & detached houses being
   poor candidates, 30s & 70s council house terraces good ones; social housing
   (I have shape files for England based on NROSH data) as many HAs and
   at-length council housing arms have been very active in installing solar.
   4. I canvassed social housing experts on twitter for likely sites, again
   skimpily listed on the wiki.
   5. The new DG Vivid layers, at least near me, are much more recent and
   better for seeing rooftop solar installations.
   6. Scanning an area you know for rooftop solar installations is not too
   arduous, and could be done more systematically for smaller areas over the
   course of the quarter. I think Colm suggested mapping rooftop installations
   as nodes & I support this (at least in first instance). The huge benefit is
   that it often highlights other things which may be out-of-date or obviously
   in need of a survey, so it can fit well with 'local patch' mapping.
   7. I hope to soon blog about my analysis of Nottingham solar in terms of
   these external parameters (FIT installations, housing age, road
   orientation, social housing etc.).
   8. For ground solar, moisture index on Sentinel imagery can be useful to
   suggest candidates. We now also have access to a cloud free composite of
   2018 Sentinel in OSM editors.

Jerry

Re: [Talk-GB] Tools to support solar panel mapping?

Obviously we are talking about home/small-scale solar here. It could get
quite involved, I'm sure that people are running whole businesses trying to
analyse satellite imagery for this. Need to keep it simple and practical
for this project, unless people have lots of time and energy to spare.

An analysis (or link to an analysis) of the official stats could be useful.
Exactly how did they make their estimates?

Another idea: councils are making an effort to put panels on their
properties. Could we FOI request them? or maybe someone has already done so.

[Talk-GB] Tools to support solar panel mapping?

[Dan S]

Hi

Related to the idea of solar panel mapping, I've had a request for
info about what sort of software tools might help support this work.
We might be using some of the familiar tools (e.g. streetcomplete,
openinframap, ... even tasking manager?).

It'd be useful to have something like
completeness-by-postcode-district. Unlike Robert's postbox tools, we
don't have any official ID numbers for the items-to-map, we just have
some official stats (to be taken with a pinch of salt) about how many
are in each postcode district - but still, that could be a start.

I'd also be interested in some tool that predicts where to look, which
might be based on analysing imagery, but perhaps more realistically
based on some mix of heuristics and official data.

Any thoughts?

Best
Dan
