[OSM-talk] Duplicate Buildings

[Pierre Béland]

My workflow in the last few days was to select/process series of way id's from Frederik list with closed iterations that look to come from the same changeset. 

Using the JOSM Overpass query function with instructions I provided earlier, it is easy to download such a block of data, validate and correct with the help of the validation functionality. 

But when there is both quadri-duplicates combined with Bad quality problem illustrated from the overpass query below, I leave it to Quality teams involved in the project (here #hotosm-project-11827) to document and correct.
