I am interested in creating fictional planet-scale maps using real data. I am exploring the idea of using multiple real projections, layered over each other, blended using fractal geometry, then exported as a single blended custom projection. Because the result is intended to be fictional, I would not need to match projections, and in fact would not want to match projections.
Can anyone point me to resources for creating and saving a custom projection.
Does anyone have any other suggestions or resources I should look at.
