Airborne laser technology has uncovered a network of roadways and canals in Cambodia, illustrating a bustling ancient city linking the country's famed Angkor Wat temple complex.
The discovery was announced late Monday in a peer-reviewed paper released early by the journal Proceedings of the National Academy of Sciences. The laser scanning revealed a previously undocumented formally planned urban landscape integrating the 1,200-year-old temples.
