In 2007, satellite images, radar, and ground surveys revealed Angkor as the worlds largest preindustrial settlement complex

In 2007, a dedicated archaeological team successfully mapped Angkor, employing cutting-edge technology and techniques. Their discoveries illustrated that Angkor sprawled over roughly 1,000 square kilometers, featuring a sophisticated irrigation network. These revelations transformed perspectives on urban growth and population density in historical societies, offering a stark contrast to contemporary suburbs. This technology has also led to the unearthing of many other concealed ancient towns globally.
