Mountain Top Removal and Vegetation change over the Ouachita Mountains from 2006-2010

Visualizations by Alex Kekesi Released on July 23, 2012

Humans actively change the Earth's landscape. Some of these changes can be seen from space through careful analysis of satellite data. In this visualization, we fly over the Ouachita Mountains highlighting (in shades of orange and red) large areas of vegetation change and mountain top removal throughout the region. NASA scientists have worked on complex algorithms that allow us to see these changes through time more easily. The data depicted here covers the years 2006-2010. Areas in orange and red are the regions have have sustained the greatest change in this 4 year period. Oranges areas represent older change (closer to 2006) and darker reds are more current (2010). Only areas with greater than 25% tree cover are shown in shades of green. A muted gray-brown color is used for areas with less than 25% tree cover.
