eggie (2019-02-27 16:56:39+00:00): Dit was je edit.. 
https://www.openstreetmap.org/node/4663432856 
Je hebt op twee plaatsen iets toegevoegd in één changeset. Dus je hebt niet na een edit opgeslagen en bent in de editmodus van Overijssel naar Branbant geschoven.
Dat kan met de linker muis waar je ook mee edit.
Het resultaat is dat adressen en wegen onbedoeld kunnen worden verplaatst.
Het is nu goed gegaan
Je zal de eerste niet zijn die vanuit Brazilë een hoekje van een huis over de halve wereld trekt.
Kijk eens naar editor JOSM. daar schuive je met de rechtermuisknop. Deze editor bevelen we ook aan vanuit het forum.

eggie (2019-02-27 16:59:09+00:00): Mijn toetsenbord schuift ook alle kanten op en kan mijn snelheid niet bijhouden.
Met JOSM schuif je met rechts. Dus minder kans op schaden. Maar toch svp je gebied klein houden om validatie makkelijker te maken.

aixbrick (2019-03-08 15:31:40+00:00): Hallo,
der Reitverein ist bereits mit https://www.openstreetmap.org/node/1838515629 erfasst.
Die Adresse ist ebenfalls schon vorhanden: https://www.openstreetmap.org/way/152796433.
Gruß
Paula14 (2019-03-08 15:47:43+00:00): Ich hatte das Stallgebäude als solches in den Eigenschaften eingetragen.
aixbrick (2019-03-08 16:34:27+00:00): OK, ich habe Adresse und Name gelöscht: https://www.openstreetmap.org/changeset/67929507. Außerdem habe ich beim Reitplatz das name-Tag entfernt. Grund: "name" ist für den Eigennamen eines Objekts vorgesehen und dient nicht zur Beschreibung. Dafür gibt es die anderen Tags oder falls die nicht ausreichen den Tag "description".
fkv (2022-01-14 18:39:03+00:00): Diese Anlagen werden in jeder Karte als normale Ampeln dargestellt, was sie aber nicht sind. Sie sind nur für die Busfahrer interessant, und die brauchen OSM nicht um sie zu finden. Alle anderen sind verwirrt, wenn sie hier eine Ampel in der Karte sehen, so wie ich, nachdem ich dort heute vorbeiging und mir keine Ampel auffiel. Ich würde solche Dinger gar nicht mappen (die Anzeigen für Straßenbahner mappt ja auch keiner), will dir aber nicht deine Mühe miesreden. Vielleicht anders taggen (statt highway=traffic_signals z.B. busirgendwas=traffic_signals oder bus:signals=irgendwas).
emergency99 (2022-01-14 19:25:42+00:00): Ok, ich würde mal darauf tippen das quasi "highway:bus=traffic_signals das akzeptabelste wäre. Werde es mal umtaggen. Und wenn ich mir die mühe machen will frage ich auf der P_T-mailing liste, ob es irgendwo tags dafür gibt. Bildete mir ein dass zumindest die nördliche Ampel früher Rot-signal hatte, aber ja, mittlerweile sind es nur noch Busampeln. Hätte die sonst nicht gemappt, aber ja, dann tagge ich mal für (oder doch gegen) den Render ;) und schaue ob es was besseres gibt. Danke für den Hinweis.
fkv (2022-01-14 19:48:21+00:00): Mich wunderte nur die südliche Ampel, aber in Google Streetview sehen beide gleich aus. Was das akzeptabelste Tagging ist, weiß ich auch nicht. Im Wiki hab ich nichts gefunden und in Taginfo nicht gesucht. Akzeptanz ist sowieso subjektiv: hängt davon ab, wen man fragt.
Joxit (2019-03-08 14:44:10+00:00): Why did you remove the building=yes tag from the Eiffel Tower ?
user_514683 (2019-02-27 15:47:25+00:00): Hi, machengwen. Welcome to OSM.
Could I just ask why you removed the name from 人民路隧道?
As far as I'm aware, that is the right name for it.

Paul-t (2019-02-28 05:15:05+00:00): The old casino and parking lot has been entirely torn down/removed. There is now a multistorey parking structure next to the new casino building and new parking lots adjacent the parking structure. But these don't show on the satellite view yet, so it's hard to place them precisely until they do. But the ones I removed are no longer in existence and the area is not accessible either, so I felt it better to remove them. Happy to take guidance if that isn't proper mapping etiquette.

Omnific (2019-02-27 17:59:46+00:00): Hey, thanks for the edits. A few note for the future: since the school grounds are already tagged with the name, we try to avoid duplicating the name on the buildings. that way, if someone searches, they only get one result. Second, for bus stops, please avoid placing the info on the road itself. Instead, make a point where the bus stops and add the info there. 

Please let me know if you have any questions!

saintam1 (2019-03-02 08:55:35+00:00): Hi Poliwrath,

It looks like you've realigned buildings to Esri imagery. I just wanted to point out that that imagery is shifted by many meters in Sofia, and, making matters worse, the shift varies in different parts of town. It's better not to use it as a reference, I think.

Just my 2 stotinki :)

jpennycook (2019-02-28 11:44:17+00:00): Hi.
Thanks for correcting the directions at this roundabout on Thorpe Lea Road.
By joining the two roads at https://www.openstreetmap.org/node/6306670899, this suggests to journey planners that you can turn left here without joining the roundabout (https://www.openstreetmap.org/way/150801603, also https://wiki.openstreetmap.org/wiki/Tag:junction=roundabout).  Some journey planners (eg those for cyclists) treat roundabouts differently to normal roads.

I'll split the entrance to the roundabout from the exit shortly.

sparky2605 (2019-02-28 13:08:39+00:00): Hi jon, the problem is that it does not believe you can for example drive from Egham station to Windermere close using this round about it routes you avoiding this round about taking you around 8km for a 1.5km journey. If you reverse the pick up and destination then it uses this correct route. Im just trying to work out how to make it work correctly. This roundabout in true life does allow you to exit and go onto thorpe lea road in thorpe direction

stevea (2019-02-28 18:36:38+00:00): Your assumption is mistaken; there is nothing wrong with my latest edits.  They are quite intentional and what you call "very strange" are explainable if/as you read our local wiki which has documented the entry of several versions of these polygons for almost ten years.  There is a long and storied history of these polygons being introduced into OSM.  Please read about it at https://wiki.osm.org/wiki/Santa_Cruz_County,_California#Landuse .

The "license" is that any data (GIS data included) produced by the state of California (as these are, since the County of Santa Cruz is a division of the state) are in the public domain.  Numerous state Supreme Court decisions have expressly declared this to be true, making the data harmonious with OSM's ODbL.  OSM mappers in California know this, now you do, too.

Wide agreement locally (around here in the OSM community) actually encourages entry of later versions (newer data which update and correct) of these landuse polygons, that is precisely what was done here.  They are part of "official" (government-produced) landuse/zoning data and accurately map to what OSM's landuse definitions are (with values of residential, commercial/retail, industrial).

The SHAPE* tags give highly accurate area and length data, and other tags, some of which some do consider superfluous, are usually in a state of flux as the local community decides for any given upload_version which tags are appropriate to keep or discard during upload, as tags do change from version to version.

Were I to start editing in your home town in Germany, before I started doing so I would perform the courtesy of researching local wiki and seeing if there were any local conventions I should know about.  Should I find them, I would not immediately assume that "something went wrong" with editing there, I would better understand that these are simply local conventions, documented in wiki and acknowledge by the local OSM community as "this is how we do things here."

By the way, many years ago, Santa Cruz won a Gold Star Award at bestofosm.org, one of only a few places in North America to receive such an accolade.  The site notes that Santa Cruz has "nearly perfect landuse!"
