I am using terrain data from terrain.party and some heavy manipulation to create a 3D model for artistic purposes. I understand the copyright requirement for the contributor label, but due to the nature of this project, having it on the front of the map is difficult. Would it be a violation to have it easily visible on the back of the map? Are there other options?
That would be best answered by terrain.party, if that’s the data you’re using for your project. We can’t tell you what their attribution requirements are. This forum is for discussing OpenStreetMap-related issues.
