Hi Charlotte,
Welcome :)
Also in the comments sometimes people put the offsets, although note I am
not aware of a way to feed iD numerical offsets (I used iD for a day or so
then went to JOSM)
I usually align to the osm features as best as possible as this *should*
result in the most accurate atleast for manual navigable maps
But be careful, the worldview and bing imagery are at different angles (I'm
new to osm hot and osm mapping too and that one bit me on the bottom about
a few days to a week ago). Results in structures having wrong shapes from
misleading shadows, etc
Nb I am new too so if I've made some wrong assumptions please do let me know
73s,
Max - mbainrot
