Animation that flys over the Ouachita Mountain range from east to west showing large areas of vegetation change south of the mountains (depicted in shades of orange and red). Print resolution still showing major vegetation change from 2006 to 2010 (seen in shades of orange and red) south of the Ouachita Mountains. Fort Smith, Arkansas can be seen in the distance. Print resolution image of the vast amounts of vegetation change (seen in shades of orange and red) from 2006-2010 southwest of Little Rock, Arkansas. Print resolution image of vegetation change from 2006-2010 (seen in shades of orange and red) south of the Ouachita Mountains on the Oklahoma side of the border. Fort Smith, Arkansas and Tulsa, Oklahoma can be both seen in the distance. 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. Related pages
