Glassman (2017-07-18 23:28:17+00:00): designated is really only for private roads that have posted signs to only allow residents and delivers. See the wiki, https://wiki.openstreetmap.org/wiki/Key:access for a better description. If the road is for destination only then the tag is appropriate. My thoughts from looking at it were that 1) it's a tertiary and 2) it can be used to connect two different areas. 

BTW - Like I said in my message to you, welcome to OSM. We are always looking for more contributors.

oormilavinod (2017-07-19 04:29:38+00:00): hey Buttered Popcorn, welcome to OSM. I just observed that you have added a node to represent a park. but according to conventions, we trace a way along the park. keep adding to the map. Happy mapping !!

user_6110846 (2020-10-02 16:46:06+00:00): я перейменую пыдстанцыю у Діброва тому що Дуброва це стара русифікована назва і щоб було однаково з назвою села
Graf Westerholt (2018-02-12 12:30:28+00:00): https://www.openstreetmap.org/node/4978333797/history

Wenn Ampelanlagen als einzelne Ampel eingetragen werden, muss man einerseits normalerweise die Richtung angeben, andererseits nicht zusätzlich eine Ampelanlage eintragen. Sonst gibt es Probleme beim Routing, da die Routenplaner die Ampel(anlagen) zählen und die Straße dann vermeiden, weil zu viele Ampelanlagen eingetragen sind. Also bitte Ampeln  korrekt eintragen.

muralito (2017-08-23 20:57:52+00:00): It's ok to be boundary=administrative and not have admin_level=*?

Should'nt it be boundary="stastistical" or other user defined value?
stevea (2017-08-23 21:11:26+00:00): It's a bit complicated.  If you haven't already, please see our wikis for both United_States_admin_level (especially cite_note=49) and WikiProject_United_States/Boundaries (especially the USMOI note in Notable exceptions).

As far as admin_level needing to be "something," as noted in the US/Boundaries wiki, it suffices that each island is U.S. territory surrounded by territorial waters, delineated admin_level=2.  So, for example, something like http://layers.openstreetmap.fr shows "USA territorial waters" surrounding each island (if you have the admin_level=2 box checked).

You are probably correct, as those wikis state that these ARE statistical boundaries.  As each member of the relation DOES have an admin_level=2 tag, it all works out, but cite_note 49 does request that we keep the relation.  Yes, we should, but if you strongly believe that it shouldn't have a boundary=administrative tag and want to change that to (user-defined, yes) boundary=statistical then I don't have a problem with that.  Thanks for bringing this up.

PlaneMad (2017-07-19 06:28:03+00:00): Hi Tinkerbell, many thanks for contributing to OSM, but it seems like many of your fictional edits are not in line with the guidelines for Pokemon Go mapping which clearly state to only map what you see on the ground: 

> do map things that exist on the ground. The map is used by pedestrians, people with disabilities, cyclists, hikers, canoeists, drivers and others. Do not add things -such as footways- that do not exist
> do add things you see (i.e. benches, cafes, fire hydrants, bicycle parking spots) or things you know (if your favorite cafe offers free wifi, the type of cuisine of the nearby diner, accessibility, opening hours, official websites, wikipedia links)

By taking a bit of effort to find real features to map in your neighborhood, you can both create a more detailed map for everyone to use as well as improve your gaming experience. 

Happy to help in case you have any questions. 
Cheers.

Regards,

Jole22 (2018-02-19 07:01:32+00:00): Hi Sperlingskauz,
thanks for the correction. According to the Wiki both notations are okay but I agree with you that without "m" is probably the cleaner version as "meter" is already set as standard.
Regards

TritonZA (2017-07-19 05:58:20+00:00): Hi there Nammala, The reason I've changed the following aeroway tag to a land use, is because it falls under the category of a military base. Please advise on how to correctly tag both if possible?

PT-53 (2019-07-19 04:52:25+00:00): Hallo  GCWMR,
Du hast an diesen beiden Weg-Abschnitten
https://www.openstreetmap.org/way/444457990/history
https://www.openstreetmap.org/way/444457992/history
jeweils highway=constrution in highway=cycleway abgeändert, construction=cycleway aber nicht gelöscht.
Wenn die Wege fertig sind, sollte  construction=cycelway noch gelöscht werden.
Gem. den eingetragenen Access-Merkmalen bicycle=yes und foot=yes ist das ja kein reiner Radweg (wo Fußgänger verboten sind) sondern ein "Geh- und Radweg" und damit ein path statt cycleway.
Wiki Path: https://wiki.openstreetmap.org/wiki/DE:Tag:highway%3Dpath
Schaust Du Dir das nochmal an?
Fragende Grüße
GCWMR (2019-07-19 19:19:16+00:00): Habe das angepasst, danke für den Hinweis.
Noch eine Frage zu meiner Weiterbildung: Wie ist dir das aufgefallen?

streckenkundler (2017-07-19 07:26:03+00:00): Hei, wieso hast du den Feuerwachturm gelöscht? Ist der abgerissen? Wäre mir neu. Dort stehen zwei Türme: Handy-Mast und Feuerwachturm, sieht man auch im Luftbild.

S.
savar (2017-07-19 09:15:33+00:00): Ja ist abgerissen worden.
In Brandenburg werden nach und nach wohl alle alten Feuerwachtürme abgerissen.
streckenkundler (2017-07-19 09:26:29+00:00): Ah. Danke... Ich denke mal, es werden nur die ungenutzten abgerissen. Einige sind zur Überwachung mit automatischen Branderkennungssystemen ausgestattet... Ich kann ja mal bei der Landesforst nachfragen. Ich fahre gelegentlich mit einer Frau von der Landesforst mit dem Zug.

Das Problem ist nun, daß der in allen Luftbildern aber noch zu sehen ist. Ich schlage vor, den Punkt zu belassen und ein abandoned: dem man_made voranzustellen und ein note=Turm ist abgerissen.

Sven
savar (2017-07-19 09:34:22+00:00): Da waren wohl auch Überwachungskammeras drauf. Aber wahrscheinlich ist die Wartung zu teuer oder man nutzt einfach weniger Türme. Keine Ahnung. Daher ja frag gerne mal nach.
Mit dem Punkt können wir gern so machen. Sobald es aktuelle Luftbilder aus diesem Jahr gibt wird man den nicht mehr sehen...
streckenkundler (2017-07-19 09:46:01+00:00): Ich schätze mal letzteres... man hat bessere Kameras... übrigens: https://wambachers-osm.website/emergency/ kennst du? 

ich frag bei Walter mal nach, ob der Feuerwachtürme auf mit verarbeiten kann.

Thank you for contributing to OSM. I noticed that you changed city for town in several changesets, I reviewed in wikipedia and in all cases they are cities, I don't understand why did you do the changes? Could you explain? thank you.

I've amended your opening hours and address tagging to suit OSM best practice. The world will now be better informed of your business. Regards Bernard
nammala (2017-07-20 04:39:37+00:00): Hi Temadri,

Welcome and thanks for contributing to OpenStreetMap (OSM). Noticed that you have been adding parks on the nodes which is not appropriate way of tagging. Please follow the wiki https://wiki.openstreetmap.org/wiki/Tag:leisure%3Dpark, parks should be in way not nodes.

Best Regards,
nammala

Mateusz Konieczny (2024-05-02 15:59:27+00:00): Hello! https://www.openstreetmap.org/node/4979027620/history has ww = 1 that was added in this edit (if I checked things correctly)
What you intended to express by using this unusual key? Is this tag needed?
Or maybe can it be expressed in a more typical way that would be easier to understand?
Or maybe this key can and should be documented as useful tagging schema?
Mateusz Konieczny (2024-05-02 16:00:32+00:00): "buildings that appear on Korean Maps" - have you copied it from some maps?
Adityo (2017-07-27 03:06:32+00:00): Halo, untuk objek yang tidak tahu nama objeknya. Tolong jangan diberi nama seperti rumah rumah rumah rumah mesjid mesjid pemukiman dll.


Lebih baik dibiarkan saja kalau tidak tahu namanya.
aixbrick (2017-07-19 11:31:49+00:00): Hallo,
die beiden Nodes 4149530074 und 4149530072, sprich die Ampeln, zu löschen war wohl ein Versehen. :-)
Die Angabe der direction bei den Fußgängerampeln verstehe ich nicht. Auf die Straße kann es sich nicht beziehen, denn es handelt sich um Einbahnstraßen, wo die Richung klar ist. Also kann es eigentlich nur einen Zusammenhang mit dem Fußgängerüberweg geben, aber der darf logischerweise in beide Richtungen genutzt werden.
Gruß
Trockennasenaffe (2017-07-19 11:45:50+00:00): Oh, da habe ich tatsächlich Mist gemacht, sorry. kann ich das wieder rückgängig machen? Aber zum Verständnis: Sind da wirklich zwei Ampeln hintereinander bzw. muss die Ampel für Autos und Fußgänger separat erfasst werden?
Trockennasenaffe (2017-07-19 11:49:53+00:00): Ich glaube ich habe die Ampeln falsch interpretiert. Ich denke das kann so alles wieder zurück.
aixbrick (2017-07-19 12:17:53+00:00): Lt. Wiki: beide Ampeln an einen Node bei einfachen Kreuzungen, Ampeln an getrennte Nodes bei komplizierten.

Danke für's korrigieren.
Austin Zhu (2017-07-20 15:55:56+00:00): hey, overrun is a part of the runway!
4b696d (2017-07-20 19:28:34+00:00): No it is not. Here is my proof:
1. These runways have a length of 3800 m wich is the length without the blast pads. Lengh with blast pads is 4000m -> https://en.wikipedia.org/wiki/Shanghai_Pudong_International_Airport
2. Quote from wikipedia: The runway thresholds are markings across the runway that denote the beginning and end of the designated space for landing and takeoff under non-emergency conditions.
The runway is the surface from threshold to threshold, which typically features threshold markings, numbers, and centerlines, but not overrun areas at both ends.
-> https://en.wikipedia.org/wiki/Runway#Sections_of_a_runway
Austin Zhu (2017-07-21 16:01:26+00:00): Yes, the runway is 3800m in length, but that's for normal use. You should also include its feature for emergency use, which is the overrun. And most importantly, Wikipedia mentions that blast pad is a section of a runway, so it definitely belongs to a runway. The "runway" which you referred to is only a section of the runway defined by ICAO. I quote here: "a runway is a defined rectangular area on a land aerodrome prepared for the landing and takeoff of aircraft". The definition does not emphasize its usage under specific condition, but both emergency and non-emergency. Besides, if you exclude the blast pad in this way, then how can you depict it?
Austin Zhu (2017-07-21 16:28:39+00:00): Plus, for visual convenience, I think it's more easier to identify the gray area if it is a little bit stretched out. Otherwise it may seems to mix with the gray taxiway although they differ in width when displayed. And visual convenience is crucial for a map, I think.
4b696d (2017-07-21 16:49:49+00:00): Please keep in mind that we are not supposed to map for the renderer. That means that we shall not map something to make it look better on a certain map.
When there is no tag for a certain feature then you should not use a different one just to make it show up on a map.
I have had a look at hundreds of airports in OSM and I can tell you that blast pads or overrun areas are generally not mapped at all. By mapping the grass around them you could achieve some sort of rendering. You can find this way of mapping at different airports. A different approach might be to tag it as aeroway:overrun, this is not documented but used on 70 ways in OSM.
Austin Zhu (2017-07-21 17:34:49+00:00): I have read several books about airport design and construction. None of them excludes the blast pad from a whole runway. I did not mean that I'm mapping for the rendering, I mean it is convenient for people who use the map. I acknowledge some of your points, but not all.
