fine

Selective revert of the separation of waterways from border lines (CS 46688164).
The roundabout w204728237 was not visible neither in bing nor Bing, exceptional source:geometry set according to previous changeset comments and GPS evidence (CS 46688307).
Selective revert of the separation of Coa Road from border lines, which caused cycle routes going over border lines instead of roads (CS 46688805).

Fully agree with hsimpson and kreuzschnabel on my practical experience using OsmAnd, and find the calculation by 'its so funny' rather theoretical.
The satnav device is just part of the information I process as a driver.

Hallo webpassenger, sehr nett. Allerdings stehen einige der Eimer auf der Strasse. Kannst du in deinem JOSM den DOP2016-Layer aus dem Geoportal einbinden, und mit deinen GPS-Daten vergleichen? osm.wiki/Geoportal_Berlin

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.

Haven't checked the node (which?) yet, however I'd also prefer to have the split at the physical separation and not the legal separation.
As the wiki talk page shows, that seems to be controversial, though.

On osm.org/way/310656818 you removed the 'wall' tag a local mapper had used. bing clearly shows a structure here, and dry stone walls are quite typical in Ireland.

I was wondering how you knew from Bing that the church osm.org/way/477636053 was roman-catholic. In Achavi it became apparent that the information was from deleted node osm.org/node/802007097
It would be good practice to keep such node alive, e.g. to use it as a corner of the building, or the entrance if known, without tags of course, to preserve the history of the information.
Thanks

Thanks, plausible additions.
Please use "service=driveway" for private driveways.
Please use a general source tag like Bing on the changeset, not on each object.

This CS apparently creates a large number of disconnected nodes, deletes them in the same changeset, and creates them again.
The CS comment is incorrect, this does not add any farmland or buildings, and does not fix any errors.
Full revert (delete remaining 149 disconnected nodes) in CS 46608967.

Similar to 46445352, this CS duplicates nearly identical landuses over existing ones, deletes a double-roof farm building to replace it with 2 less correctly mapped. Full revert in CS 46608850.

Yes I had seen this and was just tuning into the detail analysis.

You were modfying osm.org/way/123595674 which was serving both as boundary way and road, took away the road attributes and created a new way osm.org/way/478098420.

You did not realise that the old way was both in a boundary and a bus relation, thus now the bus travels on a boundary instead of a road.

Similarly to osm.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.

@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

Zeichne bitte Flächen, hier die kleinen Felder, nur dann getrennt, wenn wirklich ein Objekt (z.B. ein Track) dazwischen liegt.

Reverted in CS 46535594, see reasons there.
