Is there a way to view a map of the regions of my sov planet?
For the time being you are unfortunately limited to in-game atlases. Exporting 2D image-maps was a service James provided in the past (for permanent and for sovereign planets), but AFAIK is on hold for now. I hope Monumental takes over the practice and maybe even improves upon it with some form of automation.
Thank you for the information and the response.
