Satellite images highlighting land cover change in Virunga

A pair of Landsat satellite images have been used to identify land cover change occurring between 1987 and 2003 in the Virunga massif in the Democratic Republic of Congo. The changes seen are highlighted in coded colours: light blue shows non-forest to closed canopy forest - an example of new forest growth - while purple stands for the opposite, closed canopy forest to non-forest. Red corresponds to newly urbanised areas and yellow stands for other changes.
