subject:"\[Talk\-GB\] Tagging post towns and other addressing issues in the UK"

Hi Paul,

Once you get out into rural areas, it's sometimes the case that an 
entire hamlet is covered by a one or two postcodes. There may be named 
streets but according to RM/PAF these are ignored and such addresses 
take the form: building name/number, locality, post town, postcode. 
The more natural fit, following the structure prompted in the iD 
editor, for example, would be building name/number, street, locality*, 
postcode.
I've encountered this situation where RM addresses for a village don't 
include the street names, even though the streets have signed names.  My 
view is do include the street names. I've no idea why they are left out, 
because finding addresses in a village where the houses have names 
rather than numbers can be difficult, even when the street is known.

I wouldn't worry about the validator as long as you are reasonably sure 
the data you have added is accurate. These validation tools are very 
useful, but they are only intended to suggest things that might be 
wrong.  Mappers sometimes fall into the trap of tagging for the validator.

Even in villages with established streets and house numbers, there 
will be outlying properties where the street names will be foregone: 
S36 7GG is an example of this.
For outlying properties, I don't think there is any harm in including 
addr:street, regardless of official practice, assuming there is a 
logical street to use. Sometimes remote properties are grouped by a 
sub-locality name, in which case I would use addr:place.

Additionally, it's not clear whether name or addr:housename (or both) 
should be used when mapping anything from a a detached house to a 
building split into multiple addressable units (eg terraces, flats).
I would recommend not duplicating addr:housename and name. Generally 
it's best to avoid putting the same information in more than one address 
tag. For most addresses addr:housename is the best choice and name can 
then be used for things like business names.

Cheers,
Will

No-one in Charlbury describes themselves as living in Chipping Norton.
Honestly, no-one. It's a separate town.

Companies House data for my company shows a registered address of
11 Market
Street, Charlbury, Chipping Norton. That is not because I think I
live in
Chipping Norton. That is because, when you register a company, the
Companies
House autocomplete thing takes your postcode and fills in the
Royal Mail
post-town and other details from PAF.

(TBH, I'm not entirely convinced post towns help Royal Mail in any
case,
given the amount of mail mistakenly delivered to us that is
actually meant
for Mr G--- at 11 Market Street, Chipping Norton...)

Re: [Talk-GB] Tagging post towns and other addressing issues in the UK

Chris, what would you see as a good data model for a UK address in OSM?
Just house number/name, street, postcode? It has been mentioned a couple
of times in this thread that the "addr:" model was intended in the UK to
contain postal addresses, not any other sort of address. Are you
suggesting only storing a subset of the full postal address, and doing a
PAF lookup to get the other fields? 

Apart from the PAF, GeoPlace is the other central repository of address
info which it obtains from LAs and RM. In this document it seems to
indicate that besides the postcode, the Post Town is also assigned by RM
(see page 50):

 RM used to use postal towns when post was sorted by hand, but as soon
as mechanised sorting based on postcodes took over postal towns were
just a legacy that no one needed any more. In 1976 I posted a batch of
postcodes from my holiday in Norway. As an experiment I addressed one to
my parents as Number 10, HU14 3BA, UK. It arrived on the same day as all
the others because it had a postcode on it. So post towns were beginning
to be obsolete in 1976.

 Why does a postal town help with this? The postcode is much more
precise than a generalised post town that will cover a wide area - that
was the point of a post town.

 Of course not. Addresses are a fine idea, but real addresses that
actually exist on the ground, not some mythical, out-of-date idea used
by one organisation in the past.

 The RM PAF is not the definitive address list for the UK, it is just
the way RM sees it. It is widely used because there is no other
published list of addresses. If we ever see a proper national address
list compiled from the UPRN that local authorities maintain it will not
include any field introduced by a company such as post town. OSM can
help here by not confusing addresses with RM's muddled postal addresses.

It isn't breaking a rule. The rule is that unit + street + postcode is

standard postcodes are concerned (large user postcodes are different, of 
course, but they, too, are a minority).


It is often the case that a postcode only covers a single street. But 
that's by no means universal, and it certainly isn't rare that it covers 
more than one.


Bear in mind that the whole point of the postcode system is to 
facilitate the delivery of post by Royal Mail. The final two characters 
of a postcode are the "walk" - literally, the smallest unit of the 
postman's round. And if there happens to be a pair of short streets, or 
a short street off a longer one, then they are often incorporated into 
the same walk. Topologically, this is the most common walk:

but this is a common one, too:

or this:

If the "vertical" section has a different name to the horizontal 
section, then it will typically also have duplicate numbering. Which 
means the street name is necessary to disambiguate.


I've just had a look at the Land Registry price paid data for my 
postcode area (WR), and there are 364 postcodes within it that are 
associated with more than one street name. That's a not a trivial or 
ignorable number, by any means, even if it is only a minority of 
postcodes. To guarantee a completely deliverable postal address, you 
need the street name.

In the UK, the concept of an address is driven by the postal system.
Everybody knows their address, whether they agree with it or not, and
everybody understands that its function is to allow RM (and therefore
everybody with a route planner) to find the right letterbox.

Why do you say people don't relate to their address? The addr prefix
makes it very clear that the OSM data refers to an address. Everyone
knows their address. I agree that the use of the word "locality" in this
concept may surprise some, as it is RM terminology. But that's what
happens in data modelling - you have to find a label somehow. The
concept (of a named fuzzy area smaller than a town) exists in UK
addresses, whatever you choose to call it. If we are aiming to find a
way to represent it in OSM, then we have to make a choice as to how to
label it. It is NOT a "village" or a "suburb", even when its name may
suggest that.___

Re: [Talk-GB] Tagging post towns and other addressing issues in the UK

2019-01-28 Thread Andrzej

Hi Will,

These are very good examples, I wasn't aware of such places. They would indeed 
best fit addr:locality. How about using addr:locality together with 
addr:town/suburb/village/hamlet then? Having multiple well defined tags is good 
- they add useful information. We are not designing an internal PAF database 
for RM - OSM is supposed to be used for many different purposes, some of which 
we can't even predict. From this point of view, the richer and the more precise 
the language the better. 

I want to clarify what I meant by "almost offensive". We are asking people to 
tag their towns with names of towns they don't relate to, and to add insult to 
injury we want them to tag their own towns as "localities". At best people will 
ignore this scheme, at worst they will get very upset. In my discussions about 
this topic people felt very strongly about their home towns. 

Best regards, 
Andrzej

'city' has always been the wrong title for the field across every

of the primary location, be it 'Birmingham', 'Chipping Norton' or 
'Saintbury'. It does away with the need to make any decision on the 
'size' of the place. That additional places can be added to location to 
more accurately identify it depends on the application, so addr: may 
consist of a lot more elements than we currently cater for anyway.


The reality is that for the UK ALL we need is the Postcode to supply a 
reference to the Royal Mail 'postal address' as that is purely a Royal 
Mail invention anyway.  I personally don't see the need to add 
'addr:street' everywhere but that is what people seem to prefer. Adding 
several more addr: fields to EVERY building is just taking things too far?

Re: [Talk-GB] Tagging post towns and other addressing issues in the UK

Having said that, I still don't understand the objections to addr:town
and addr:village. Can anyone come up with an example of an address
where they wouldn't work? I normally don't care about names but
locality sounds almost offensive.
To me 'locality' just sounds neutral. I don't particularly object to
addr:town and addr:village, but it does mean we end up with at least
three tags rather than one, because in cities suburbs often don't fit
easily into those tags, hence the use of addr:suburb.

Business parks and other campuses are not localities - their names are
written before street names, not after them.
In my experience this often isn't true, perhaps look at more examples.
It is relatively common for business park and industrial estate names to
appear after street names.

Examples:
Lenton Lane Industrial Estate, Nottingham

Fully agree.

The notion that I should tag addresses in Charlbury with "addr:city=Chipping
Norton", a town 6 miles away, just because one private delivery operator[1]
uses Chipping Norton as an optional part of their addressing is... one of
the more outlandish ideas I've heard in OSM tagging circles, and that's

The accepted paradigm is that the address should represent the postal
address, and not any administrative relationships. As you will know RM
have their own particular ideas of the geography of the UK, all done for

Hi,

When working on post codes in East Anglia I realised the current 
address tagging scheme is insufficient for even fairly basic 
scenarios. I have already discussed the issues with some of the most 
experienced mappers and like to bring these issues to your attention. 
Robert has summarised his ideas in 
https://wiki.openstreetmap.org/wiki/User:Rjw62/UK_Address_Mapping


The bottom line is, I would like to be tag commonly used addresses 
without losing information and without resorting to addr:full.


Issues:
1. Post towns (most pressing one because there is a lot of confusion 
around it). The UK is fairly unique in that not every town is a post 
town. This makes it impossible to tag e.g. Station Road, Histon, 
Cambridge CB24 9LF.
Wiki recommends addr:city to be used for tagging post towns 
(Cambridge) but then how do we tag Histon?
- Robert recommends sticking to the current meaning of addr:city and 
using addr:town and addr:village for town and village names, which, 
although not in wiki, are already being used in the UK. I like this 
solution because it is very explicit in what each addr: key means and 
it doesn't redefine addr:city.
- SK53 prefers using addr:city for everything (towns, even villages) 
and either not tagging post towns (they can be seen as a an internal 
detail of a closed Royal Mail database) or using a new tag for it, 
like addr:post_town. It is a simple solution, results in Histon being 
called Histon and not Cambridge (without introducing new tags for town 
and village names) and is commonly used. It is also a bit confusing 
(what exactly is a city?) and I think we we should at least support 
tagging post towns.


Key questions:
a) addr:city for post towns or towns and villages?
b) how to rag remaining information (respectively, towns and villages 
or post towns,)


2. Tagging addresses within campuses, business parks etc. There is 
addr:place but it is supposed to be used instead of addr:street. 
Again, Robert has a fairly decent proposal for that using addr:place 
or addr:locality and addr:parentstreet. Please comment.


2a. should buildings in campuses be tagged with 
addr:buildingnumber/name or addr:unit? I would prefer 
buildingname/number (as they are often subdivided) but these seem to 
be associated with addr:street.


3. Similar to (2) but for buildings. Tagging buildings that have e.g. 
a single name but multiple house numbers?

ndrw6

Re: [Talk-GB] Tagging post towns and other addressing issues in the UK

Hi Colin,

Dependent and doubly dependent localities are technical terms and without 
having access to PAF most mappers wouldn't know which one to use. And if they 
did, that could be considered a copyright infringement. Also, it just doesn't 
sound right. No one asks "which dependent locality do you live in". I agree it 
matches PAF very well, though.

I agree towns and villages are less precise but since we already have them as 
admin levels that would be the easiest and most intuitive solution. We already 
have addr:suburb and addr:hamlet so that would be a natural extension, and one 
which is already in use in the UK. 

I agree with you on addr:parentstreet. The issue here is that house numbers and 
names are associated with either addr:street or addr:place. So if we were to 
introduce addr:substreet or addr:campus that convention would have to be 
changed. For this reason I suggested using addr:place as a dependent 
thoroughfare.This would only require allowing both street and place to be 
defined together.

Best regards,
Andrzej

Re: [Talk-GB] Tagging post towns and other addressing issues in the UK

Perhaps OSM UK could step in and endorse address tagging practices once a 
consensus is reached? In the end it does not matter what tag names we use as 
long as the whole scheme is consistent and rich enough to describe common use 
cases. 

So far, I see addr:city=posttown is a popular solution, which I am happy about. 
But it would have to go with something like addr:town/village to denote 
dependent localities. Otherwise we won't be able to convince mappers from 
smaller towns to follow this convention. 

Another idea, if we allowed addr:place and addr:street to be used together, 
addr:place could be used as "dependent thoroughfare" with no(?) other changes. 

Best wishes, 
Andrzej

Re: [Talk-GB] Tagging post towns and other addressing issues in the UK

2019-01-27 Thread Colin Smale

Hi Andrezej,

I would oppose addr:village for the Dependent Locality as it invites
incorrect usage. There is no reason to overload an existing tag with a
different meaning to its current usage. In the UK, a village is not
simply a neat subdivision of a town. I think addr:locality and
addr:sublocality would be better, as this would (correctly) imply a
possibly fuzzy boundary which possibly crosses formal admin boundaries. 

Regarding streets/thoroughfares, the main thoroughfare is addr:street -
that is clear and established usage. We are looking for a solution for a
"substreet" and moving the main thoroughfare up to "addr:parentstreet"
to make room for the dependent thoroughfare in "addr:street" feels wrong
as it gives addr:street different semantics under some conditions. Note
also that the word "thoroughfare" has probably been carefully chosen to
allow application to things other than simple streets with adresses
neatly on each side. I would also instinctively expect a campus to be
more of a locality (subarea of a Town) than a super-street. Maybe
someone with access to PAF data can see what data is in what fields for
some address on the CSP. 

It wouldn't surprise me if subbuildings were used for "Unit 1",
"Building A" etc. That doesn't sound/feel at all unreasonable.

Good point.I would also add campuses in this category. Although I am not 100% 
sure if that's how they are classified in PAF.

True, but full address would still include extra information. We can infer 
addr:country and addr:county from admin areas but everything else should be 
_possible_ to tag.

It should still be possible to encode a typical full address with tags. 
Sometimes people will want extract the full address from OSM, sometimes they 
will want to search for a part of it. Even if someone is searching for a house 
number and a postcode alone it is useful to see if e.g. a street name of the 
result matches expectations.

Re: [Talk-GB] Tagging post towns and other addressing issues in the UK

2019-01-27 Thread Colin Smale

David, thanks for offering some updates. 

By the way, I am not asking questions because I personally want the
answers - I am fully aware of how these things work. And because of
that, and because OSM tries to model reality, I believe we need some
kind of anchor-point for our thinking in order to converge on a proper
solution. In many countries postcodes/zip codes are associated with
geographic areas; the UK, as frequently happens, uses a different
paradigm. We need a clear statement of the intention for the addresses
in OSM, and my belief is that they represent postal addresses as per the
PAF. PO Box numbers are not applicable to OSM, as they cannot be related
to a location useful in OSM. The discussion is just about Dependent
Locaiity, Double Dependent Locality, and Dependent Thoroughfare. If we
can define what OSM tag should be used for these three fields, we have a
model which is sufficient for all UK addresses. 

Of course, it is an option to decide to NOT represent this level of
detail in OSM. In that case, expect mappers to make up their own
solutions, and this discussion to resurface every few months.

At low level (commercial areas, academic campuses, hospitals) that's not really 
the case. They are not as formalised as admin areas.

Re: [Talk-GB] Tagging post towns and other addressing issues in the UK

Hi Colin,

This is broadly in line with Robert's proposals. However, it raises questions 
about:

1. tagging "dependent localities" - they can be towns or villages. Are you 
happy with addr:town, addr:village for this purpose? Reaching consensus on that 
would be a major step forward. 

2. Tagging "dependent throughfares". I think they could be used to tag 
"building name, Cambridge Science Park, Milton Road, Cambridge". This could be 
addr:place except in OSM addr:place should not be combined with addr:street. 
Or, like in Robert's proposal, addr:street+addr:parentstreet. Except that CSP 
is a campus, not a street. 

3. Tagging subbuildings. Addr:unit is available but is fairly limited (unit 
names?) and vague. 

4. PO Box - I haven't thought about it. Is that something that we would include 
at all in a geographical database? Perhaps if it is associated with a business 
that has a known location but uses PO Box as its address? 

Best wishes,
Andrzej

This is the one that actually normally causes questions.  It is quite 
common to have named terraces, and to have runs of maisonettes numbered

Firstly, addr in OSM is generally postal, not geographical.  As 
indicated elsewhere containment (or is_in) define the geographical place.


Secondly, in practice the only parts of the address you need are the 
detailed destination point code and the post code.  However, I 
discovered that the postie on the beat also needs the street name to 
avoid having to look it up from the postcode.


The bar codes for Walksort only contain the postcode and two character 
detailed destination.  (Is there a potential project there, to capture 
these.  Everyone who has received utility bills will have their own 
code, but they are only available to paying customers, as far as the 
sender is concerned.)

PO Box is not really relevant.  In most cases it is attached to a post 
office building.

I’d hope these would inherit from whatever the address is enclosed in.

Hi,

When working on post codes in East Anglia I realised the current address 
tagging scheme is insufficient for even fairly basic scenarios. I have already 
discussed the issues with some of the most experienced mappers and like to 
bring these issues to your attention. Robert has summarised his ideas in 
https://wiki.openstreetmap.org/wiki/User:Rjw62/UK_Address_Mapping

The bottom line is, I would like to be tag commonly used addresses without 
losing information and without resorting to addr:full.

Issues:
1. Post towns (most pressing one because there is a lot of confusion around 
it). The UK is fairly unique in that not every town is a post town. This makes 
it impossible to tag e.g. Station Road, Histon, Cambridge CB24 9LF.
Wiki recommends addr:city to be used for tagging post towns (Cambridge) but 
then how do we tag Histon?
- Robert recommends sticking to the current meaning of addr:city and using 
addr:town and addr:village for town and village names, which, although not in 
wiki, are already being used in the UK. I like this solution because it is very 
explicit in what each addr: key means and it doesn't redefine addr:city.
- SK53 prefers using addr:city for everything (towns, even villages) and either 
not tagging post towns (they can be seen as a an internal detail of a closed 
Royal Mail database) or using a new tag for it, like addr:post_town. It is a 
simple solution, results in Histon being called Histon and not Cambridge 
(without introducing new tags for town and village names) and is commonly used. 
It is also a bit confusing (what exactly is a city?) and I think we we should 
at least support tagging post towns.

Key questions:
a) addr:city for post towns or towns and villages?
b) how to rag remaining information (respectively, towns and villages or post 
towns,)

2. Tagging addresses within campuses, business parks etc. There is addr:place 
but it is supposed to be used instead of addr:street. Again, Robert has a 
fairly decent proposal for that using addr:place or addr:locality and 
addr:parentstreet. Please comment.

2a. should buildings in campuses be tagged with addr:buildingnumber/name or 
addr:unit? I would prefer buildingname/number (as they are often subdivided) 
but these seem to be associated with addr:street.

3. Similar to (2) but for buildings. Tagging buildings that have e.g. a single 
name but multiple house numbers?

Best regards,
ndrw6
