This photo was taken by an automatic K-12 camera, using black-and-white infrared film, from a Viking sounding rocket that reached a height of 227 km. This scene spans parts of New Mexico, Arizona, Nevada, California, and northwest Mexico (upper Gulf of California on the left).

Limitations
Only variables affecting radiance/distance are retrievable.
Technical capabilities of current technology (spatial-temporal-spectral resolution).
Surface observation (little depth penetration). Atmospheric influences.
