I'm doing computer art with images mixing low zoom areas with high zoom areas automatically. So far, the only images I can use reliably are vector graphics images, since they support infinite zoom without pixellation. Here's an example:
I warped a vector graphics image consisting of just a simple tiling pattern out to infinity. If I can get a high enough detail image, I should be able to use it to do the same thing without any nasty pixelation. I know there are extremely high detail satellite maps covering the whole world. What I'd like is a massive archive full of such maps that I can use offline to create these images. Does such a thing exist?
