I have the same issue, I have a nautical chart with me and I want it to display into the screen like Google or even Bing at the default map provider.
I know that what you create in the tile set, is not the map or the “map provider” itself, it’s just a frame from the provider map being saved and cached for guidance in a safely autonomous environment.
I think that what you want is to change the provider, not the tile set, like me, is that correct? If it’s a yes, I need to solve this either, and I still looking for answers too.
