Join the Letter Hunt from Space with Aerial Bold by Alex Barth.
From the post:
Imagine you could write text entirely made up of satellite imagery. Each letter would be a real world feature from a bird’s eye view. A house in the shape of an “A”, a lake in the shape of a “B”, a parking lot in the shape of a “C” and so on. This is the idea behind the nascent kickstarter funded project Aerial Bold. Its inventors Benedikt Groß and Joey Lee are right now collecting font shapes in satellite imagery for Aerial Bold and you can join the letter hunt from space.

Letters are recognized from space, based on letter forms. But, more letter forms are needed!
