harcher, what is really the source here? It is being uploaded too fast for manual tracing, which makes it seem like an import. And "source" is probably not "Digitalglobe", because the features do not align to either Digitalglobe Standard or Premium. They do align, however, quite closely to Bing.

Hi bdiscoe, I'm having trouble viewing the structures in my browser, but I recall uploading this changeset. The data is an import; the structures were delinated offline in QGIS using recent images downloaded directly from Digitalglobe EV Webhosting. However, in some cases, there was conflicting with existing structures in OSM, so I deleted duplicated structures from the existing layer but kept those that showed areas not previously uploaded into OSM. In this case, the structures overlapped frequently with the area with roads, which was cleaned to prevent duplication, but did not in the other two thirds.

Hi, thanks for the information. I'm glad you remember the changeset since it was only 5 hours ago :-) It sounds like you do know what you are doing. That "Digitalglobe EV" must just happen to match Bing. BTW, what does #akros mean? It would be good to put more in your changeset comments to explain what is being uploaded (like, mostly buildings in this case).

Feels like days! Thanks, I can add more detail; as you may suspect from the quick rate of upload, we're on a time crunch to upload structure files for a malaria spray project in Eastern Province Zambia, so neglected comments (but not quality efforts). I have two more to upload this morning, and I'll try to add more detail. Thanks for the quick response to the uploads.
