Cotopaxi is one of South America's most famous volcanoes and one of its most active ones. With its 5911 m it also ranks among the world's highest active volcanoes (26th highest).
The digital elevation model of Cotopaxi volcano acquired by SRTM. With its resolution of 25 m x 25 m, is so rich in detail that you can even make out an inner crater with a diameter of 120 m by 250 m inside the outer crater (800 m x 650 m). Blue and green correspond to the lowest elevations in the image, while beige, orange, red, and white represent increasing elevations. (Image Credit: NASA Earth Observatory)
