As I've pointed out before, if OSM supports a specific system, it
amounts to us picking a winner , and I really don't think that is a good
idea. w3w wants to make money from royalties, google wants to avoid
paying them. Both have a financial interest in us adopting their
systems. IMHO when one eventually "wins" we can start supporting it
then, before one of them pasts the post, it is premature.


Or OSM could support a variety of different coordinate systems (so long 
as they are free/open).
It is possible to search for latitude/longitude on osm.org, why not also 
allow UTM/MGRS, Plus codes, Geohash etc.

OSM doesn't have to endorse one particular system as the best.

The approach that I - and everyone else who applies the same logic -

4. A tells B the plus code.
5. B enters the plus code into OSMAnd, and OSMAnd applies the reverse
computation function.
6. B knows where to go.

This approach requires extra functionality in OSMAnd to apply the plus
code computation, but libraries and code for that exist. This approach
does NOT require that someone else has added the particular location to
OSM before - it works everywhere on the planet. Also, this approach does
not require OSM to store all the plus codes.
OsmAnd already supports Plus codes. You can do exactly this already. No 
extra coding required.
Go to general settings, then coordinate format, then set 'OLC'. Then it 
will display Plus codes for any location on the map that you pick. It 
works fine for any object on the map, or even blank spaces if you want. 
No need for any specific tags.

When asked for his data's source for this widespread edit & he said "old

It would be good to have some better tags for phoneboxes (which may or 
may not actually contain a working phone). The phonebox is often a 
distinctive landmark, especially the classic red ones, and many are now 
listed buildings.
I see Yorvik Prestigator is adding the tags for covered=booth and 
booth=KX300 etc. Are these tags documented anywhere? It seems like a 
weird use of covered, as that is for things above the object, not 
necessarily surrounding it.


Why not a specific tag for telephone_box or something?
It would also be useful to tag that it is a classic red phone box, even 
if you don't know what exact model it is.

I am looking at getting a GPS Watch. Does anyone have any advice?  My 
primary concerns:
1) Ease of getting GPX tracks out of the watch so they can be uploaded 
to OSM. Seems like a lot of the devices require you to first upload 
the track to their proprietary site from where you can download the 
GPX... sounds like a hassle.

2) Positional accuracy
3) Recording fidelity (e.g. once per second, once per five seconds, etc).
4) Battery life. Ideally > 10 hours on a single charge while recording 
tracks.


You could look at a Garmin Forerunner. Probably the most popular GPS 
running watches.
Most of the newer models record tracks in FIT format, and work as a USB 
mass storage device. So you can just plug it into your computer, then 
copy the files off.
There are a few options for converting from FIT to GPX. eg GPSBabel 
works, or Garmin Basecamp. You don't need to upload to any website. Some 
more advice here: https://wiki.openstreetmap.org/wiki/FIT


Accuracy is usually not bad for the newer models. Though can sometimes 
be a bit out, especially under trees. Not too surprising for such a 
small GPS receiver, and swinging your arms about etc.


Recording rate depends on the model, most of the cheaper models only 
have "smart recording". This usually gives 1 point per 5 seconds or 10 
seconds or so. Though it should record more points where needed, ie a 
twisty path. The higher end models can record 1 point per second.


Battery life again depends on the model. Some of the cheaper ones are 
only about 8 hours, or up to 15 or 20 hours on others. Especially if you 
disable extra features, eg heart rate or Bluetooth. Some of them have 
"UltraTrac" mode, which gives longer battery life, but a less detailed 
track.


Or another option is the Garmin Foretrex 601. It is much bulkier and 
heavier than most watches, maybe a bit too big to wear on your wrist. 
But OK if you attach it to a rucksack strap. It has much better battery 
life - it claims 48 hours. It uses AAA batteries, so you can carry 
spares if necessary. And probably more accurate - should be a bigger 
antenna, and it can use GPS, GLONASS and Galileo.

Click on "Where am I?", then it gives you the latitude/longitude for the

I don't think lakes and rivers should be inners, because they are still

are 'on top' of the island, not 'holes' within it.


Though yes, managing huge relations is a problem. They will inevitably

it could be split into smaller sections?


The Garmin maps is another question. They seem to label the whole area

I really do feel like we are missing a trick here. As the map becomes
more and more complete it becomes harder and harder to find something
to map (example: I spend more time trying to find missing footpaths that
I can map on a circular walk now than 2-3 years ago).

An app that helps people find what's missing whilst out surveying could
really help. I only wish I had the skills and time to do this.


The Post Hoc map has the option of exporting a GPX file. That will 
include any missing boxes, or boxes with missing refs etc.
So you could download that GPX, then load it onto a Garmin, or on a 
phone app etc. For Android, you could try OSMAnd, it can load GPX files. 
Or maybe Maps.Me, if you convert it to a KML file.


Then you can go out and survey them. Note the Royal Mail locations can 
be very inaccurate, some of them are on completely the wrong street, or 
hundreds of metres away. So it can be difficult to actually find the 
postbox. And there are a few on the Royal Mail list that have now been 
removed, or where the number on the box doesn't match the list.

along are horribly common.  Examples:

http://homepage.ntlworld.com/pete.meg/wcc/facility-of-the-month/May2009.htm
http://homepage.ntlworld.com/pete.meg/wcc/facility-of-the-month/June2013.htm
http://homepage.ntlworld.com/pete.meg/wcc/facility-of-the-month/December2013.htm

How would you tag those?

I have no idea if your example falls into that category, is mis-tagged,
or what.


2 of those are not cycle lanes - the 1st and 3rd are paths separate from 
the road. But they are also part of an NCN cycle route.
So they could be tagged as highway=path (or highway=footway), with 
bicycle=no, plus maybe something like bicycle:pushing=yes. Plus adding 
them to the route relation.


I'm not sure what is happening with the second photo, is their a cycle 
lane marked on the road or not?

If mapping them as separate ways, you can tag them as highway=footway + 
footway=sidewalk.

It is not 360°, but at least there would be some images of remote areas.


For the GoPro, I find its usually more useful in timelapse model.
ie taking a photo every second, or maybe every 5 or 10 seconds, depends 
on what you are surveying and how fast you are moving.


The still photos are usually much better quality and higher resolution

Do none of those cameras offer the logical alternative to timelapse - a
'spacelapse' mode that uses the camera's knowledge of position through
its GPS receiver to capture a picture every ten meters instead of every
ten seconds ?


None of the GoPro cameras have GPS built in, so not possible with them.

Are there any pavements, are they separated by kerbs? Or are people

Is there a low speed limit. ie 20mph or less?
Any traffic calming to slow vehicles down, eg speed bumps, or chicanes.

If you take a look at the what links here link from the wiki you'll

The thing is that if you add something as a tag in wikipedia
({{tag|maxspeed|15}}), you'll automatically get a link to a wiki page
for that tag. And since it is pretty senseless to have a seperate page
for every different speed limit, they are redirected to a general page
about the maxspeed tag.

I would leave them in.


For the wiki, you should use the tag template like {{tag|maxspeed||20}}
ie 2 | vertical bars after the key. Then it doesn't create a link to the 
value.


But there's nothing wrong with redirect pages on the wiki anyway. It 
helps people find the correct page, and avoids creating duplicates.

Depends on just what sort of road it is, and how it is signed. ie are

Often a Private road sign is specifically referring to motor vehicles,

In Scotland, you would generally have a right to walk or cycle there

Yes, some of the OS OpenData boundaries have been added to OSM. But they

This morning I came across a name tag on a power line
http://www.openstreetmap.org/#map=17/53.18607/-1.14961. I believe this
is now quite a common practice ( 8% of lines in an 3-month old
data-set). Personally I deplore it:

  * I have never found a convenient sign on a power line giving it's name.
  * It is not derived from ground-truth.
  * It is not verifiable by other mappers.
  * It's tagging for the renderer (which may not work once the rules for
name have been revised in CartoCSS)
  * The names appear not to be names, but descriptions, we have a
suitable key for this, oddly enough called description.
  * Some name tags include National Grid. we have a perfectly suitable
tag called operator for this information.
  * I very much doubt that National Grid use names of this type for
sending out line engineers.
  * Most of these names just appear to describe the two end points of
the line. OSM is a geo-database this information can be found by
suitable queries.

Given that adding non-verifiable names seems to /de rigueur/ I propose
that in homage to Edmund Crispin I propose we name a random selection of
power=pylon as The Pisser.

More seriously I suggest that these name tags be removed and replaced by
suitable use of operator and description.


I think some power lines do have names, mostly the major transmission 
lines. Yes, this is usually the names of the places they are between.
eg the big example in Scotland is the Beauly-Denny power line (not much 
mapped in OSM yet). This is the official name from SSE / Scottish Power, 
and it has been widely reported in the news, with a public enquiry etc. 
And there are some signs on the ground, eg 
http://www.geograph.org.uk/photo/2759088
Yes, these signs are probably temporary during construction, so the name 
will be less obvious when the line is finished. But I think it should be 
recorded in OSM in some way.


Or other SSE projects, including some power lines with names: 
http://www.sse.com/WhatWeDo/AssetsAndProjects/
I have seen a few of these signed on the ground, during 
construction/refurbishment  works.


I would agree that things like the operator or voltage shouldn't be 
tagged as the name, you can use the specific tags for these.

I think it varies by country, but I am pretty sure that in the UK the

275kV.


I think in England and Wales, the transmission network (aka the national

In Scotland, the transmission network includes 400kV, 275kV and 132kV, 
and is owned/maintained by Scottish Power/SSE.


Anything below these is classed as the distribution network.


The smaller overhead lines that you see on wooden poles are about 11kV.


Its possible for up to 132kV to use wooden poles. I think 132kV is 
usually on steel pylons, but wooden poles might be used in rural/more 
scenic areas.

33kV or 11kV is usually on wooden poles. Also 66kV is used sometimes.

So for the UK electricity network, the full range of voltages would be 
400V, 11kV, 33kV, 66kV, 132kV, 275kV, 400kV.

Not really.
Scotland/England/Wales are clearly administrative boundaries, and they 
are tagged as such in OSM. And they fit in the hierarchy of admin 
levels, ie below national boundaries, above council areas etc. They are 
comparable to states in the USA.


So not relevant to tagging Native American lands.

Do we have a scheme for tagging UK railway bridges with their numbers?
I have looked on Wiki, and can't find anything, and my local bridges
are either not tagged; or tagged (for example) ref = B4124:

http://www.openstreetmap.org/browse/way/103233329

which does not identify that number as being a NetworkRail reference
(if indeed it is, being on a road overbridge maintained by the local
authority).

If we do not have something more specific, I'm happy to draft
something for discussion.


That ref=B4124 is presumably the road number, not the bridge number.
The tag bridge_ref (or bridge:ref or ref:bridge) is in fairly common use 
for bridge numbers.


I'm not sure if there is any common standard for railway bridges. What 
is signposted can vary. Sometimes its just a painted number, sometimes 
its a proper plate, including the line reference.
Do you include the line reference as part of the bridge reference? I 
think its a good idea to do so, when its known. eg tag as something like 
bridge_ref=ETN/1601

I've seen mention of both rights of way and core paths.
What's the difference?
Who are the authorities that have legal obligations?
What legal obligations do they have?
Do they have to maintain a definitive map?


Core paths were created by the Land Reform Act 2003.
All of the local authorities and national park authorities are required 
to produce a core path plan, which should include the main routes for 
walking, cycling, horseriding, canoeing etc. So the core paths may 
include paths, as well as tracks, driveways, public roads, and rivers.


It seems most of the authorities have now produced a core path plan, 
though some of them are still consulting on it.
I'm not sure if its actually a legal requirement, but the guidance says 
that the authorities should promote the core paths. So this means they 
will usually be signposted in some way. I'm not sure which areas have 
actually done this.

It will warn if there is at least one name:XX tag, and the name tag

I don't think it handles multiple names in the name tag, separated by

According to this list, 208 accounts have added more than 10k house

It is quite possible that the program has bugs so if you notice

From a quick check, the numbers seem about the right for me - only a 
couple of hundred house numbers so far. Though I'm planning on mapping

It would be good if it could include addr:housename tags as well. A lot

The above statement is almost correct:

2. As soon as I cross the dateline to the West the maps appear to be OK
at large area resolution, but ALL detail (including the map) disappear
at distance resolution of about 50 Km and smaller.
3. The above problem appears to be confined to a vertical strip of
western longitudes, starting at the date line and reaching as far west
as north-east New Zealand, the Fijian Islands, etc.
Although I can not be 100% positive about this, the South Island of New

of Lake Taupo. Further tests have shown that Tasmania and eastern
Australia are OK.
The problem stated above exists whether I have my map assembled by the e

Here's the OSMI view:

Here's an example way it is flagging up:
http://www.openstreetmap.org/browse/way/181450407

Can someone point out where I have gone wrong, or is this a problem with
OSMI?


I think the problem is it is tagged as add:interpolation=odd, when its 
not actually an interpolation way. An interpolation way should be a 
line, with a node at each end tagged with add:housenumber. So it doesn't 
really make sense on a closed way / area, or a node.


Its clear that you want to say that building has the numbers 15,17,19 
etc, though I'm not sure what the best way of tagging this is.
Using addr:interpolation for this is documented here (at the bottom of 
the page, for Multiple housenumbers on one object): 
http://milliams.dev.openstreetmap.org/postcodefinder/tagging/



The second issue is with roads that don't really exist. For example, a
row of houses have addresses for OSM Terrace but front straight onto
OSM Road. These terraces often appear where new homes are built and
there's no space for addresses on OSM Road. You can see a couple of
examples here: http://tiny.cc/93p6kw

Should I just ignore those and treat them as warnings, or doing
something else?


This may depend on how it is signposted on the ground. You could say 
OSM Terrace is an alternative name for that section of OSM Road, so 
tag it as alt_name. Or possibly name:left / name:right, if it is just 
one side of the road.

I would agree that these 'unofficial' routes don't really belong in OSM.
But depending on how your blog works, there are ways of showing the 
route on a slippy map.


eg you could draw the route on Gpsies, then use the IFRAME code that it 
provides to embed the map on your blog. Note by default this will show 
it on a Google map, for an OSM map you have to add the mapType=mapnik 
parameter, see this page for details (in German): 
http://www.gpsies.com/page.do?page=linkus


There are other options for track drawing websites with OSM maps listed 
here, though I'm not sure which support embedding: 
http://wiki.openstreetmap.org/wiki/Track_drawing_websites

Also note some blogs don't allow iframes.

Or if you have a Wordpress.org blog (ie hosted on your own server), then 
you can use the OSM plugin: http://wordpress.org/extend/plugins/osm/

This lets you show an OSM map with a GPX track overlay.
See an example on my blog: http://craig.neogeo.org.uk/blog/?p=61
Though I don't think this is possible on a Wordpress.com blog.

The OS Locator data does have Gaelic names in some places.

Though it is inconsistent, with English names for some roads, Gaelic 
names for others. I have also noticed a few places where it seems to 
have both languages, so it has a separate box for each.
For Stornoway, the Gaelic names are in the name= tag, with name:en for 
English.
But for Portree it is mostly the English name in the name= tag, with 
name:gd for the Gaelic names. Its debatable which one should be

Yes, you can use the OSM data to create a map of whatever you like. For 
how to, you can start with this page: 
http://wiki.openstreetmap.org/wiki/Rendering
Some of the software can be a bit complicated to setup, the easiest 
option is probably Maperitive.


Or if you just want to add simple icons as a layer on top of a standard

Are you sure you mean Geofabrik, I didn't think they provided any maps

Anyway, this is a known issue with Mkgmap, the software used for

properly. It seems it works on some Garmin devices but not others. See 
http://wiki.openstreetmap.org/wiki/Mkgmap/known_issues


I don't know if this has been improved in more recent versions of 
Mkgmap. I see Mkgmap now has an option --index which creates MDR and 
MDX index files, for address search in Mapsource, but I don't know if 
you can transfer these to the GPS device.
There is also the option for --road-name-pois which will create a POI 
for each road, which you can then search for. The problem with this is 
it creates lots of ugly dots everywhere, and it clutters up the POI 
search with road names.

You could try generating some maps with these options and see if they help.

Nominatim.)

can someone involved in the Nominatim comment on this, and what needs to be
done either on the map data side or the Nominatim side to get results that
are more consistent with what an ordinary user-off-the-street might be
expecting?


I'm not involved in Nominatim, but some comments anyway:
You can go to this page and search for a place: 
http://nominatim.openstreetmap.org/
In the results, click the little link for Details, which will give 
more details of how Nominatim figured out the address. So for Biitig 
Road it gives this page: 
http://open.mapquestapi.com/nominatim/v1/details.php?place_id=14428803
As you can see from that page, it is using the place=county node for 
Saratoga. If counties etc are just mapped as nodes, then Nominatim has 
to guess which county a place is in, based on which node is nearest. And 
in this example, the node for Saratoga county is nearer to Biitig Road 
than the node for Rensselaer county.


So its much more useful to map counties as areas/multipolygon relations, 
and delete the place=county nodes. If you have now done this, and its a 
complete border, and tagged correctly, then Nominatim should use it for 
the address.
The same applies for cities/towns/villages etc - if they have defined 
boundaries, then its a good idea to map them instead of just a node.


Have you got a link for the way/relation for Rensselaer County? I could 
have a look at it, and see if its tagged correctly and complete.


Note that nominatim.openstreetmap.org page says its using data from 
2010/12/28, so newer changes won't show up yet.

Probably more useful (especially for imports) to tag the source on the

One option:

See for instructions: http://josm.openstreetmap.de/wiki/Styles
Note there are separate map styles for default maxspeed (kmh) and mph

Though its currently lacking a section for the UK. I think the UK should
be much the same as the global defaults, at least for the roads.
The paths/bridleways/cycleways should be a bit different from the
defaults, as access on foot is usually allowed on all of these. It
should probably also be different for Scotland vs England  Wales etc
due to the rather different the access laws.

Though I don't know if there is any maps / routing software using these

Also, i think there are a few roads in the UK where cycling is banned,
but they haven't been tagged as such (eg parts of the Edinburgh

I think it would be helpful if something like OpenCycleMap highlighted
roads tagged with bicycle=no - it would make the missing bits more

 specifically? I just tagged them note=Waymarked footpath

You could tag them as lwn=yes (for 'local walking network').
I've done this for a few paths that seem to be part of a local network 
of signposted paths.

There are also core paths, which will be designated by local councils, 
and should be signposted etc. Though I don't think any of these have 
been created yet (there's been various consultations over the last few 
years).
I think it would be worth having a designation=core_path tag for when 
these appear.

 Secondly, again while you can walk anywhere, I came across a number of
 occasions where tracks temporarily end, then restart further on, and in
 between is a relatively easy cross country route which you can follow
 (unsignposted) where you don't have to scale drystone walls, scramble
 through undergrowth etc. AFAIK such recommended routes are not
 generally put into OSM but need a separate project, but does anyone do
 otherwise?

If there doesn't appear to be any sort of path on the ground (or signs 
that other people have walked that way), then I probably wouldn't map them.

You could tag them as highway=path, trail_visibility=no
But the question is where do you draw this recommended route? Should 
it be the most direct line between the visible paths at each end?

It suppose it would be more useful to map what's actually on the ground,

 never tried to restrict public access, nor is the private sign
 anything other than a statement that the road is private, it does not
 say, for example :Private, no entry. As far as any user is concerned,
 they can treat it as a normal road.

 I suppose the appropriate thing is to change access yes (or whatever the
 normal state is), and then add a note to ensure it is not re-instated.
 Does that sound right?

access=yes means the public have a legal right of access, ie its a right 
of way for all traffic.
It sounds like that's not the case here. The owner could probably 
restrict access to the road if they wanted to.

Probably better to tag it as access=permissive, ie the owner gives

 list?

 I don't think there is a single wiki page that lists them. I think
 it was me added the second relation to the Cambridgeshire (some
 weeks ago) and Essex (this morning) pages. I knew they existed as
 the same boundary way near me is in multiple relations.

They should be listed on this wiki page:

Or some more lists linked from here:

Re: [OSM-talk] Documentation on Editing Relations

 Hi,
 I have always tried to avoid using relations (never really accepted that
 is better than adding route= tags to ways, and they seem to complicate
 things quite a lot), but I am trying to tidy up some long distance
 footpaths that have been done as relations.

 The concept of relations is fine, but I am really struggling to find the
 instructions on how to edit them properly without breaking anything -
 for example:
 If I know a relation number, how do I load it (I don't mind which
 editor!) - the bit of countryside I am editing does not include it, so
 it does not appear in the JOSM relations list, but I have a number from
 a Wiki page.

In JOSM, you can do File - Download object (or Ctrl+Shift+O), then 
enter the relation number to load it.
Or you can do File - Open location (Ctrl+L), and enter the URL of the 
API page for that relation. Note it has to be the api.openstreetmap.org 
address, the browse page doesn't work.

 I have pretty much worked out how to add ways to relations
 using JOSM's relation editor, but haven't quite worked out how to
 re-order them, apart from doing it manually - is this possible?

In the relation editor, there's an icon on the left hand side for 
A..Z, which will sort the relation. Also the icon underneath that will 
reverse the order.

 Is there a command line way of adding ways to a relation - for example,
 rather than doing it by clicking on things, I would quite like to do
 add ways to relation  where route=Pennine Way or name=Pennine Way.

Not exactly command line, but you can use the Search feature in JOSM (on 
the Edit menu, or Ctrl+F). eg search for Pennine Way will select 
everything tagged as that. Then open the relation editor, and you can 
add all of the selected objects to the relation. Just make sure you are 
not adding ways that are already in the relation - JOSM should warn 
about that. You can also search for objects that are not part of a 
relation by using -child.

 Any pointers would be appreciated.  Sorry for being dumb - I must have
 missed the documentation somewhere?

I'm not sure if there is any particularly good documentation about this. 
There is some stuff on the Relation:route page, including a step by step 
guide for creating a new route relation, but not much about the more 
advanced editing: http://wiki.openstreetmap.org/wiki/Relation:route

The JOSM relation editor was significantly improved / changed fairly 
recently, I don't know if theirs any documentation about its new 
features. The JOSM help seems to be a bit lacking.

 path isn't Spawn of Satan! ;-)

 What is Spawn of Satan, here in the UK at least, is foot=yes. ;-) This
 is completely ambiguous, either use designated for a designated right of
 way or permissive if access is by discretion only.

What about in Scotland, where you have a right to walk / cycle / ride a 
horse just about anywhere (so long as you are responsible), even if its 
not a designated right of way?

   In our case of photo geo tagging this is no issue I think.
 Please tell me if I'm wrong here.

 For photo geo-tagging the main problem is that you can set the camera time to
 a resolution of one minute, not one second, and the camera time will drift,
 probably inversely related to the purchase price.

 So some form of fiddling is needed to accurately place the photos, trying a
 few secs forward and back until they line up on the map with known features.
 So whether your GPS is UTC or GPS time is not a practical problem.

The easy option is to take a photo of your GPS device with it displaying 
the time. You can then adjust the time offset from that.

I suppose there might be a bit of lag between the GPS device 
receiving/calculating the time, and displaying it on screen, plus lag in 
the time taken for the camera to save the photo, which might be a few 
seconds.

Though it shouldn't make a lot of difference in accuracy, unless you are 
taking photos while driving past at 50mph.

Re: [Talk-GB] Cycleway on a Bridge

[Craig Wallace]

On 18/02/2010 17:06, Molescott wrote:

 When you come up either of the curved cycle access paths to the bridge,
 the cycle lane/track/path/way is the first thing you come across on the
 bridge. This part is actually a fairly wide pavement with a standard
 kerb, from which you can step down into the road proper. The road itself
 then has one lane going out over the bridge and then another lane coming
 back. On the far side is the bridge parapet, no pavement. Some of the
 distance along the bridge is joint bike/walker use, with nothing painted
 on the pavement. Other bits have a centre white line on the pavement
 with bike/walker symbols on.
 I am confused as to how to tag this way since the bike part isn't in the
 road marked out as a lane, but up on the pavement.
 If I add a bridge to a separate bike tag I'll get two bridges over the
 water, which there isn't.
 I think maybe I'm looking at this too deeply and there's a simple answer.
 Any suggestions please?

 From what you describe, the cycleway is separate from the road, so 
should be mapped as a separate way, tagged as highway=cycleway, plus 
bridge=yes for the part that is on a bridge.

Though as you say, the problem with this is the standard map renderings 
will show it as a separate bridge. This is a fairly common problem, and 
also happens with dual-carriageways etc going across bridges.
Unfortunately I don't think there is a proper fix for this currently.

There is a proposed bridge relation, which would let you group several 
ways together as part of a single bridge: 
http://wiki.openstreetmap.org/wiki/Relations/Proposed/Bridges_and_Tunnels
Though AFAIK that's not used by any renderers. Hopefully this will be 
fixed sometime, and bridges drawn correctly.
