Airborne lasers produced a detailed map of the lost city of Mahendraparvata, including highways and previously undiscovered temples, hidden beneath dense vegetation in Cambodia.

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 formal urban planned landscape integrating the 1,200-year-old temples.
The airborne lasers produced a detailed map of a vast cityscape, including highways and previously undiscovered temples, hidden beneath dense vegetation atop Phnom Kulen mountain in Siem Reap province. It was the lost city of Mahendraparvata.
"What we have now with this instrument is just 'bang' — all of a sudden, an immediate picture of an entire city that people didn't know was there before, which is remarkable," University of Sydney archaeologist Damian Evans, the study's lead author, told Australia's The Age in a video interview from Cambodia. "So instead of this kind of very long gradual process, you have this kind of sudden eureka moment where you bring the data up on screen the first time and there it is — this ancient city very clearly in front of you."
