[OSM-talk] mspray stealth organized mapping

[Mikel Maron]

Before everyone jumps to revert undelete block etc I’ve gotten in touch with the teams at Akros and am helping to work out what’s happening here and resolve. More soon.

It is gone thanks to https://overpass-api.de/achavi/?changeset=72427535

BTW how one may undelete delete buildings? Straight revert will delete new ones,
what may be not needed.

Use reverter plugin in JOSM, copy buildings to a new layer, delete reverter layer, save?

Is there some script that I can run with "revert deletions only in changeset XYZ"?

Looking at Achavi, red outlines make us think objects were deleted. But in fact, the buildings were simply slightly moved to realign to DigitalGlobe imagery (not Bing).  And no correction of geometry was made, even where too many and unsquared angles to represent a rectangular building. Also Tags are systematically added:  
    "mapper"="mspray4"
    "source"="Akros"
