I've reverted this changeset via changeset/29741467

relation/908959 got also damaged.

Hello, it seems that you've damaged the following boundary due to your edit: relation/3249599

Thanks, I've used the PicLayer Plugin in JOSM for tracing: http://josm.openstreetmap.de/wiki/Help/Plugin/PicLayer

ok, hopefully it's fine now: changeset/29540671

Hi, it seems that we've produced an editing conflict and damaged the coastline. I've splitted the coastline to reduce version conflicts and it seems that you've also edited the coastline in the same time. I'm trying to resolve this issue.

Hello gm360st, please do not edit boundaries with the iD-editor. This editor ist inappropriate as it has no built-in validator. You've damaged several boundary relations due to your edits, for example: relation/194938

Bitte verlasse dich beim Mapping nicht nur auf Bing-Bilder. Diese haben im Hochgebirge teilweise einen starken Versatz und extreme Verzerrungen. Die Bing-Bilder liegen in diesem Bereich teils 100-200 Meter daneben.

For the moment I've mapped the current state of the reef. [1] The image I've used for mapping is from 22.02.15: http://i.imgur.com/OTNWAnE.png
As you can see on the image there isn't an airport yet so I'd propose to remove it or to tag it with something like proposed=aerodrome

Best regards, 4rch

The mapper added also other islands [1] which are currently under construction. I've asked him three months ago which sources he used but he didn't answer my questions.

When you compare the OSM coastline with current satellite imagery of the island [2] you can see that it can't be retrieved from satellite imagery like Landsat. It seems to be retrieved from plans/shapefiles/etc.

Hi Wesam5588, before you import something to OpenStreetMap you have to contact the community and follow the import guidelines [1]. As it seems that you didn't follow the import guidelines I've asked the Data Working Group to remove this import.
The tags which you've uploaded are redundant and invalid.

Best regards, Arch

Hi, it seems that you've broken another boundary instead ;)
relation/68617

Please use appropriate changeset comments so that others can understand your edits. Why have you moved this administrative boundary? Was it incorrect? way/30273432

please don't make "tagging for the renderer" which means: "avoid using incorrect tags, or otherwise skewing the data you enter, to make things show up in a specific way on the map rendering. "

this are no footways

Hi, please take a look at the following boundaries:

relation/4525209
Both boundaries are invalid and you seem to be the last editor

Nein, da "Ein- und Ausgang Schloss" nicht der Eigenname des Platzes ist sondern lediglich einen beschreibenden Charakter hat. Der Haupteingang wurde schon hinreichend erfasst mit entrance=main: node/100062814
