Add a note on the main OSM site - maybe with expected finish date of
road works -- might help as a reminder.

Cheers,

There is also the temporary affix:

https://wiki.openstreetmap.org/w/index.php?title=Proposed_features/temporary_(conditional)#Example_4:_Temporary_highway_bridge

I'm not entirely sure how well supported that is by routers etc though.

Re: [Talk-GB] New Bridge Gunnislake

[Mateusz Konieczny]

It is closed for repairs, so maybe highway=construction construction=primary
would be better? 

It seems that it will be more likely to be caught if forgotten, really old 
highway=construction
is far more suspicious that old access=no.

Old highway=construction would be caught for example by StreetComplete.

There is also https://wiki.openstreetmap.org/wiki/Key:opening_date 

that allows to specify opening date - what makes possible to
run query detecting objects that are supposed to be open now.

Query example for London: http://overpass-turbo.eu/s/HEq 
 (pan map
and press run to get results for other place).

Re: [Talk-GB] New Bridge Gunnislake

[Devonshire]

Saw this on the local news last night. A 30+ mile diversion is going to cause a 
few problems over Easter if they can't get it sorted. I am not that close but 
have mapped this area a bit in the past.

No real view either way on adding the restriction to OSM. Good for users who 
keep their data up-to-date but potentially not so good for people who update 
infrequently.

Re: [Talk-GB] RFC: Solar panel mapping in the UK

[Tony Shield]

Hi

In the last 18 months or so I've noticed that most of the new housing 
estates near me (Chorley Lancashire) have roof mounted solar panels. Is 
there a new regulation that all new builds have solar?

Re: [Talk-GB] RFC: Solar panel mapping in the UK

[Jez Nicholson]

I'm with you on a Solar Quarterly Project, given my work on UK Renewable
Energy mapping.

AFAIK the list of large solar farms on the wiki is completely up-to-date.
There aren't many linked to sites that have already been mapped yet, but
will show the gaps when they are.

[Talk-GB] RFC: Solar panel mapping in the UK

[Dan S]

Hi all,

I'd like to propose that for OSM in the UK we have a project to map
solar electricity panels (photovoltaics or "PV").

Why? In brief:

* We can do this! It involves a nice mix of aerial imagery, local
on-the-ground observation, etc; and anyone can do it, in the town and
in the countryside.

* The tagging is already pretty well-defined.

* We have auxiliary sources of information (from UK government
departments) to help us know where to look, to help us estimate
completeness, etc.

* The data will be useful - e.g. to help the National Grid predict how
much solar power they'll receive on any given day (allowing them to
reduce the amount of coal power they burn), or to help select good
locations for new installations. I've been in conversation with people
who would use the data for these things. It's also good mapping in
general - these things are often visible landmarks etc.

* We can visualise our work delightfully using Russ' OpenInfraMap:
https://twitter.com/openinframap/status/1113362591642992640


There are two parts to this: rooftop solar (there are about 900,000
installations in GB), and large solar farms (there are about 1,000 in
GB). OSM currently has about 13,000 items in GB tagged as
generator:method=photovoltaic.

For rooftop solar see info we've compiled here:
https://wiki.openstreetmap.org/wiki/Renewable_energy_in_the_United_Kingdom/Rooftop_Solar_PV
For large solar farms, there's this list (from a while ago but quite useful):
https://wiki.openstreetmap.org/wiki/Renewable_energy_in_the_United_Kingdom#List_of_under_construction_and_operational_UK_Ground_Mounted_Solar_Farms

We could focus on just one of these or on both. In each case there's
plenty of mapping to do, as well as a bit of cleanup or augmentation
of existing items.

In both cases OSM UK people are already having a look into it and
doing useful mapping, so I'm sure there will be some useful advice
from experience. (See e.g. Jerry's blog, linked from the wiki page
above.)

This could be a quarterly project. Currently it's a request for
comments. What do you think?

[Talk-GB] New Bridge Gunnislake

[ael via Talk-GB]

With some hesitation, I have just added access = no to New Bridge
in Gunnislake.
https://www.openstreetmap.org/way/608610775

This is one of only two major routes across the lower Tamar, so it is
of major importance for routing applications.

The bridge has been closed after an accident damaged the structure, and
it has been suggested that may be shut until 1st May.

I know the area fairly well, and I believe that I had edited the bridge 
several times in the past, although the history now only seems to go back
for around a year with edits from non local (armchair?) mappers.

The relevance of that comment is that I am not aware of any very local
mappers.

Anyway, have I overlooked a way to tag a temporary restriction like
this? I have put a note in my dairy to remind me to check the tagging in
a week or two, but I could still forget ... which would be unfortunate
:-)
