How do you add buildings when the map is crooked?

lemmy.dbzer0.comHow do you add buildings when the map is crooked? - Divisions by zeroSorry, crooked isn’t the best word, but I can’t think of a better one. I’m still quite new to OSM, and I want to start adding the buildings in my town. When I open the edit option though, the map overlay is at an angle. It’s not a massive amount, but it’s enough that you can see one sometimes two sides of most buildings, so the roof isn’t aligned straight down, if that makes sense? I live near Aberdare in South Wales, and you can see that where someone has added some buildings in the town centre at some point, they’re now not aligned with the map overlay: https://www.openstreetmap.org/edit#map=20/51.71312/-3.44499 [https://www.openstreetmap.org/edit#map=20/51.71312/-3.44499] Do I draw around the roof that I can see on the map? Do I edit the existing buildings so that they line up with the overlay? I’m not sure what the best course of action is for something like this. Thanks in advance :)

@Tippon Imagery often needs to be re-aligned to match up with local traces. The wiki has some guidance on the general "Using Aerial imagery" pages and on handling off axis imagery on the page for roof modelling.
