Here’s a print of Chinatown, San Francisco.
Instead of gargoyles, we’re using more appropriate bits of icon and text to recognize the corners.

This is not information that you’d be able to get from a satellite image.
It’s also information that don’t really need a GPS for: the roads are already in place, but they need extra eye-level information.
