Not sure the best place to put this... but researchers have used DSCOVR/EPIC data to create a simulated single image of the Earth - then used the light curve to create a two dimensional map of the Earth that manages to capture the rough shape of North America, Eurasia, Africa, and Australia/Antarctica.

A similar technique could be used for any exoplanet with static albedo features (such as oceans or continents).

Interesting article about locating a telescope near the Lagrange point, which would use diffraction through the outer atmosphere to create an image with up to 45,000 amplification.
