Home to nearly nine million people, Mexico City is the densely populated, high-altitude capital of Mexico.
Sentinel's optical camera clearly shows the difference between the densely built city centre and the vast surrounding vegetation.
The brownish-grey patch in the right corner of the central part of the image is a flat area with some agriculture, criss-crossed by canals. Mexico International Airport is also visible, and further along the dark green rectangle is Lake Nabor Carrillo.
This is a reservoir, encompassing more than 14,163 ha, which is 41 times larger than New York's Central Park.
Mexico City sits in the Valley of Mexico, also called the Valley of Anáhuac, a large valley in the high plateaus at the centre of Mexico, at an altitude of 2240 m. This valley is in the Trans-Mexican Volcanic Belt, which is at least 2200 m above sea level. Mountains and volcanoes surround it, with elevations reaching beyond 5000 m.
