What I'm trying to say is : there is no way of knowing the "source" since a map will be pretty similar everywhere.

https://www.reddit.com/r/lasercutting/comments/dcelcp/copenhagen_on_wood_two_layers_of_birch_trotec_45/f28504p lol, maybe if this guy was smart enough to not post on this same account that he's using their data.

For what a stranger to this conversation knows he even could've taken the picture himself, you just can't know. There a some streets, rivers and parks, those will appear on any map or picture.

I'm no expert on mapping software but given that multiple people in this thread were able to spot where the data came from, a moderately skilled lawyer could tear OP a new ass hole if they wanted to.
