How would I go about making ultra high res maps of Earth regardless of how much space they would take up?? I saw the grand canyon mod and know its possible. I just need a few pointers as to were to get started. The steps that I need to take and programs that I need to do so. Once I get it down I will do local requests for people and eventually try to do the whole Earth, although at that res. I imagine it would be a TB lol.. Thanks.
