Mt. Kilimanjaro
This image shows a perspective view created by draping a Landsat image over the elevation framework
from an SRTM data set for Mt. Kilimanjaro.
It was created from an original map produced from data obtained by NASA's
Shuttle Radar Topography Mission (SRTM). Using Google's free Picasa2 program, the
color and lighting were enhanced and then sharpened to obtain the image above. The
original image can be viewed at the NASA link above.
Mount Kilimanjaro (Kilima Njaro or "shining mountain" in Swahili), the highest point in Africa,
reaches 5,895 meters (19,340 feet) above sea level, tall enough to maintain a permanent snow cap
despite being just 330 kilometers (210 miles) south of the equator. It is the tallest free-standing
mountain on the Earth's land surface world, rising about 4,600 meters (15,000 feet) above the
surrounding plain. Kilimanjaro is a triple volcano (has three peaks) that last erupted perhaps more
than 100,000 years ago but still exudes volcanic gases. It is accompanied by about 20 other nearby
volcanoes, some of which are seen to the west (left) in this view, prominently including Mount Meru,
which last erupted only about a century ago. The volcanic mountain slopes are commonly fertile and
support thick forests, while the much drier grasslands of the plains are home to elephants, lions,
and other savanna wildlife. This 3-D perspective view was generated using topographic data from
the Shuttle Radar Topography Mission (SRTM), a Landsat 7 satellite image, and a false sky.
Topographic expression is vertically exaggerated two times.
