will_p (2017-03-02 12:27:29+00:00): Welcome to OSM.

I see you have added a footway along Hampden Street. You have added it down the centre of the street so that it mostly shares the same nodes as the road itself (mapped as highway=residential). 

Please note that we don't map pavements in this way. If you wish to indicate the presence of pavements along a road, the easiest method is to add the tag sidewalk=both/left/right to the road itself. See http://wiki.openstreetmap.org/wiki/Key:sidewalk for more details.

Pavements are sometimes mapped using separate ways, but usually only when there is a barrier physically separating them from the road itself.

Regards,
Will (will_p)
SK53 (2017-03-02 15:41:29+00:00): Can I add that the local convention in Nottingham is definitely NOT the addition of pavements as separate ways. Adding pavements makes the data harder to maintain and may complicate routing to the point that pedestrian routing no longer works.  Adding a sidewalk tag is the local convention.

Thanks,
Jerry (SK53)
rainerU (2017-03-04 13:27:07+00:00): Les bâtiments sur le plan cadastral sont décalés par rapport à la réalité. On le voit bien quand on les compare aux images ortho. Aussi bien le décalage que la position des bâtiments entre eux varient.  Ce n'est donc pas un décalage systématique du à l'angle de la prise de vue des photos ortho. Il y a des cas évidents comme ici :
https://www.openstreetmap.org/way/478053604 
https://www.openstreetmap.org/way/478053372
https://www.openstreetmap.org/way/478053599 (deux bâtiments voisins, l'un décalé au nord-est, l'autre au nord-ouest)

Il y a aussi des bâtiments qui ne sont plus que des ruines où il faudrait ajouter ruins=yes : https://www.openstreetmap.org/way/478053585

et d'autres qu'on ne voit pas sur les images ortho et qui n'existent probablement plus : https://www.openstreetmap.org/way/478053694

Il faut aussi vérifier que la voirie existante n'interfère pas avec les bâtiments importés et ajuster la voirie si c'est le cas comme ici :

kayle (2017-03-02 13:49:37+00:00): Len pár poznámok k úpravám.
K správnemu zaznačeniu obecného úradu, či škôlky je potrebné doplniť aj ďalšie značky (tagy)
Obecný úrad potrebuje značku amenity=townhall
http://wiki.openstreetmap.org/wiki/Cs:Tag:amenity%3Dtownhall
a škôlka zas amenity=kindergarden
http://wiki.openstreetmap.org/wiki/Cs:Tag:amenity%3Dkindergarten
.
Ďalej do názvu (name) nepísať všeobecné názvy ale iba vlastné (teda nie "obchod", "škôlka", ...)
Taktiež napísať tam rôzne iné veci. Ako v tomto prípade "súkromná"
https://www.openstreetmap.org/way/478057939
Na určenie možnosti vstupu je tiež špeciálna značka (tag), v tomto prípade access=private http://wiki.openstreetmap.org/wiki/Cs:Key:access

V prípade otázok sa stačí obrátiť http://groups.google.com/group/osm_sk

Veľa zdaru do ďalšieho mapovania. :)
kayle (2017-03-08 11:26:17+00:00): Ešte pár otázok.
Toto sú nejaké penzióny alebo prečo tie názvy?

Na kaviareň to je nejaká malá budova, alebo to je krmelec pre zver? Potom to značenie nie je správne.
Polarbear (2017-03-07 15:29:10+00:00): This CS deleted school w255709094, just to redraw the nearly identical campus in w478058571. Same with boat house w255709093 and w478058570. Original versions restored in CS 46654702. School campus is sharing the river boundary, that is fine. Boathouse was sharing a node, fixed. 
A river defining a border was drawn in parallel. New way removed and tagging restored in CS 46654924.
For resolving a forest multipolygon into a simple, two original outer members were deleted, instead of using the larger one to extend it to the full outline. Not restored.
eggie (2017-03-02 13:02:03+00:00): Niels,
Het is niet goed als verschillende soorten landuse over elkaar heenliggen. http://overpass-api.de/achavi/?changeset=46519446
Waarschijnlijk is dit stuk nooit opgeruimd na de import van de 3dshapes landuse, want het dateert uit 2009. 
Ik zal het omtaggen naar place locality area yes. Dan blijft de naam erop staan.
Op ons forum is juist een discussie over naamgeving van gebieden. e zijn daar nog niet uit.

trigpoint (2017-03-02 18:19:36+00:00): Hi, welcome to OSM. Thank you for your edit however you have created a number of duplications. McDonalds and TNT were already mapped using ways, mapping with nodes are a bit of a step backwards.
Also the name tag is for an actual name, and should not be used for descriptions such as 'playground' and 'car wash'.
If you could have a go at fixing these it would be appreciated, ask if you need any help.
Cheers Phil
muralito (2017-03-07 03:10:28+00:00): Hi AlaskaDave:

Some tags of the elements you added doesn't have any meaning in OSM. 

It's probably an import that you did it unadvertedly, and could be improved to be more useful.
AlaskaDave (2017-03-07 04:53:20+00:00): Yep, you're right. I used a list from the USFWS website and didn't bother to clean up the old tagging. It's on my todo list.
AlaskaDave (2017-03-07 05:22:32+00:00): Done.
MCDA (2017-03-02 15:11:41+00:00): Seriously? All OSM wiki pages say to use source=Bing ie http://wiki.openstreetmap.org/wiki/Key:source and JOSM fills this in automatically when I have the bing layer added.  Why do you feel the need to change this accepted standard?
Polarbear (2017-03-02 22:12:48+00:00): Well, first of all this is a mechanical edit violating our policies, see https://wiki.openstreetmap.org/wiki/Automated_Edits_code_of_conduct

Second, this change is pointless, as both versions, bing or Bing, correctly explain the source being used, thus you needlessly increase the version count of the objects. 

Third, we now prefer to tag the used sources on the changesets, not on the object, unless the object has a very specific source. So we can better track multiple sources used over time. 

[German]Du benutzt JOSM/de, falls du kein Englisch verstehst, schreib mir eine PM und ich erkläre die Probleme auf deutsch.[/German]

(@KDDA - my JOSM does not add any source tags to objects automatically?)
MCDA (2017-03-02 22:24:16+00:00): @Polarbear - I don't know about your JOSM, but you will see that most of my edits have this tag, which was automatically added when I have the Bing layer active in JOSM

This user has done the same in a number of other edits in the local area, but has mixed them in with some useful edits, therefore I am reluctant to revert them.
Polarbear (2017-03-02 23:58:12+00:00): @KDDA - ok, JOSM can add them to the changeset (not the object), in particular if you click "obtain from current layer" in the upload menu it adds all currently visible layers. Cool.)
Back to the topic, the user started some "area unglueing" in Germany some days ago, I am currently analysing and partially reverting those. Most likely those "Irish county border separations" need to be reverted as well. Achavi will help you: http://nrenner.github.io/achavi/?changeset=46520040
DD1GJ (2017-03-02 13:05:44+00:00): Nein. OpenWeatherMap orientiert sich an richtigen Städten und da gibt es bereits Krumbach (Schwaben). 

Krumbach als Ortsteil gibt es in Baden-Württemberg 6 mal, im Bayern 7 mal, in Hessen 2 mal. Selbst wenn es gefunden würde, will wohl niemand eine so große Auswahlliste. Das Wetter dürfte mit Fürth im Odenwald übereinstimmen.
mueschel (2017-03-05 13:31:59+00:00): Hi,
17 of the nodes have the strange key "|ODS:nevenadres" - could you check that? Pipes in keys are not common.

SK53 (2017-03-02 15:30:17+00:00): Can you please stop needlessly changing Bing to bing. It totally obscures other changes which you are making. You're changeset comments are not adequate to understand what you are doing. Please discuss this type of edit with the local community first.
SK53 (2017-03-02 15:37:15+00:00): Can you please stop these edits immediately you are creating bad data https://www.openstreetmap.org/way/369383412/history
Polarbear (2017-03-02 22:29:57+00:00): Besides the Bing issue, you are messing up county boundaries. Boundaries might be legally defined by a stream or river. Look at this example:
https://www.openstreetmap.org/way/71656812 was serving both as a county boundary (admin_level 6) in a boundary relation, and a waterway. It might not be ideal to have the county names on the stream, however you mad the situation worse: 
You removed both the waterway and the name tag, and created a new, parallel way, https://www.openstreetmap.org/way/478089726 and added the waterway and the county names to the new stream. 
Not only you created separate geometries for which would be the same; you also added nonsensically the county names to what is now only a stream.
Polarbear (2017-03-07 02:18:15+00:00): Fivemiletown edits 46526305+46525145+46523754 reverted in 46637434 and selectively restored in CS 46637891, 46639210, 46639252, 46639371, 46639474
MCDA (2017-09-08 12:27:50+00:00): Can this please be put back to how it was before.  The waterway is NOT called Tyrone / Fermanagh
SomeoneElse (2017-09-08 12:37:43+00:00): @KDDA - there are only 2 bits called "Tyrone / Fermanagh" left - http://www.openstreetmap.org/way/490542618 and http://www.openstreetmap.org/way/369383412/history - it's probably easiest just to change them manually.
Polarbear (2017-09-08 21:43:03+00:00): There was one of WernerP's changeset still on my todo list from the series of repairs above, which were done manually. Let me check that manually at daylight tomorrow if that is the reason for your question.
Polarbear (2017-09-09 08:38:09+00:00): Checked my records, seems my unfinished repair is in Ballinasloe/RoI, not the Fivemiletown/NI here. 
Anyway, it seems that for w369383412, I had removed the Tyrone / Fermanagh name from WernerP's edits in March.
On the other hand, for w490542618 and w261564260, KDDA himself added waterway=stream to a new and an existing border way (April/May).
Polarbear (2017-09-09 08:42:28+00:00): The names of the counties and the admin levels are in the respective border relations. 
Thus the border way as a member (waterway or anything else) can have its natural name or no name. Anything else might be in a note tag.

I hope he will react and learn. We do need mappers with good local knowledge.

PT-53 (2017-03-02 18:42:47+00:00): Hallo deprado,
Du hast auf dem Federseeparkplatz schon wieder eine Grünfläche eingezeichnet. Die ist mit 6,4 m bei weitem zu breit. Du orientierst Dich anscheinend an den Baumkronen. Maßgebend ist aber allein die Fläche am Boden.
Auf die Grünfläche hast Du noch mehrere Bäume eingezeichnet. Natural=tree sollte nur für besonders markante Bäume, die als Orientierungshilfe dienen können, verwendet werden. Was ist mit den vielen anderen Bäumen dort ? Willst Du die auch noch einzeichnen ?
nammala (2017-07-17 08:35:22+00:00): Hi pizzaiolo,

May I know the reason behind adding this feature in the changesets which has irregular tagging combinations.

Regards,
nammala
pizzaiolo (2017-07-17 10:59:27+00:00): Hi nammala, thanks for reviewing the changes. I'm generally following the conventions at https://wiki.openstreetmap.org/wiki/WikiProject_Esperanto

Is there any specific tag that you'd like to discuss?
nammala (2017-07-17 12:44:17+00:00): I am concerned about the admin tag where the small area is being tagged as admin tagged and also the place tag which you have been added
pizzaiolo (2017-07-17 12:46:13+00:00): I don't think it was my intention back then to mess with admin-related tags, so feel free to change back any mistakes you found there, if you wish.
nammala (2017-07-17 12:50:03+00:00): I am not much familiar about the admin boundaries so can you please cross check and take necessary action on this way http://www.openstreetmap.org/way/33120283
pizzaiolo (2017-07-17 14:01:28+00:00): How can I check with iD? I can't really use JOSM.

Spanholz (2017-03-02 18:01:04+00:00): What are you doing here? Military checkpoints T-Rex stuff? Is this fantasy? Please only add existing stuff to OSM. So please delete imaginery things and start mapping existing landmarks.

Spanholz (2017-03-02 19:10:10+00:00): Thanks for your fast response. My fault for accusing you to add false data. I wouldn't call these points military checkpoints. 

Maybe you can add those ways as: highway=track + 4wd_only=yes

For those points maybe ask at https://help.openstreetmap.org/ but it's definetly no army checkpoint ;)

Antonio Nazareth (2017-03-03 13:06:27+00:00): Eu moro aqui  na cidade e estou fazendo as   alterações pelo josm!
Antonio Nazareth (2017-03-03 13:46:53+00:00): uso alguns tracks de pedalada para ajustar as imagens e fazer os trajetos
smaprs (2017-03-03 14:55:18+00:00): ok, valeu, belo trabalho!

GerdP (2017-08-26 05:56:46+00:00): Hi!
Please review :
You used highway=mini_roundabout on ways. The tag should only be used on nodes. 
I think https://www.openstreetmap.org/way/164349393
is a mini_roundabout, but sat images show an obstacle in the middle of https://www.openstreetmap.org/way/154079742 
so that is probably a junction=roundabout?

Polarbear (2017-03-03 00:24:41+00:00): Similarly to https://openstreetmap.org/changeset/46445352 it seems you are "unglueing" areas, which is not necessary if they are adjacent. And you do it by deleting the existing lines and their history.

Please consider also that for polygons having a high number of nodes it is reasonable to compose them from multiple ways in a relation, you removed such relations here with redrawing similar ways.
