Here's a ss of that building, now if you dont mind, i'll return to tracing.

I'm not using ottawa'ortho I know its from 2005. Im using the 2014 from carleton u that their gis department took(2014) http://carleton-u.maps.arcgis.com/apps/PublicInformation/index.html?appid=a9602c9a15fd4db898c7b8a264442038
As I am taking classes there, I have access to it.

Don't believe me? https://www.nga.mil/MediaRoom/PressReleases/Pages/2015-16.aspx

Also DevonF, if a user cant add 1000ish buildings without being the spanish inquisition, osm will fall behind everyone. It's probably why digital globe and a relief effort have forked OSM and started contributing to their own fork and not OSM, because small time mappers waste their time.

Unfortunately DevonF I cannot as although carleton University allows creating derivative works and tracing from their aerial imagery, they do not allow to copy/redistribute it(only for students/faculty at Carleton university), doing so may be punishable by revocation of access to the imagery.

So if we are to follow the rules, yes I mind posting a screenshot of Carleton's dataset as it may result in the termination of my access.

I've looked on Bing and although it's offset(all imagery in Aylmer is, which only local knowledge would know) You can still see the details (though a bit pixelated) you can still trace from it with a good decerning(from bad imagery) eye

Would saying CarletonU ortho(2014) and City of Ottawa ortho be sufficient?

I'm sorry, the source field doesnt allow for long ass urls(character cap in JOSM) I will specify my proper sources in future changesets. The only reason you cant access the imagery from CarletonUniversity is because it's in their library that their GIS deparment conducted in 2014(20cm ortho) anyone from carleton university can review the additions. I'm sorry my changeset is only reserved to local mappers and local knowledge.

I've learned from past events, its not worth importing. I've even reported imports to the DWG recently. I decide to do something manually and by the books and get threated with a revert. This is pardon my language bullshit.

I've also been using ortho photos that are compatible with OSM tracing from the city of ottawa and carleton university(carleton you need to be a student to access the data, sorry)

This is most definitely not an import, I'm currently on mobile and will get back to you. This addition done by hand via mapbox, bing and local survey of the area. I have no desire to import data anymore as it will just get reverted if not passed through the proper channels. I'm currently tracing buildings in gatineau while waiting for the city of Ottawa to get approved. If you dont believe I've been tracing buildings in gatineau for a while now, but stopped because I felt like doing other tasks. https://twitter.com/jamesExiledLedg/status/727534863717437441

If you revert this, this just proves what is written in my profile

Merci

Thanks, continue your awesome effort :)

so there are no new object to replace the ones you deleted(buildings are demolished)?

Why are you deleting a bunch of objects instead of updating the existing objects?? Same with this:
osm.org/changeset/44371614

Pourquoi as tu suprimer des édifices?

Tu devrais utiliser un compte d'import pour ceci. Est-ce que tu as de la documentation sur le wiki pour ce import?

why so many delete nodes/ways? Are you correcting something?

Only did that for Chesterville as the other cities I've been to and have local knowledge of them. Chesterville had a wikipedia article attached so when I saw that I attached it's wikipedia id at the least...
