The data comes from the "Mountains of the World" database published in 2002 by the United Nations Environment Programme (UNEP), as well as the United States Geological Survey (USGS) "Global Multi-resolution Terrain Elevation Data 2010" (GMTED2010). The graph combines planar and elevation forms to visualize the geographical study of mountain definition and classification, showing the distribution and proportion of mountainous areas in each continent on a flat surface, as well as the global proportion of mountain areas of different classes in terms of altitude.
Definitions
class1. elevation >= 4500 meters
class2. elevation < 4500 & elevation >= 3500
class3. elevation < 3500 & elevation >= 2500
class4. elevation < 2500 & elevation >= 1500 & slope > 2 degree
class5. elevation < 1500 & elevation >= 1000 & slope >= 5 degree OR
elevation < 1500 & elevation >= 1000 & local (7 km radius) elevation range > 300 meters
class6. elevation < 1000 & elevation >= 300 & local (7 km radius) elevation range > 300 meters
class7. Inner isolated areas (<= 25 sq.km in size) that do not meet criteria but surrounded with mountains
