These images show an area of deforestation in Riau Province, located on the east coast of Sumatra Island, Indonesia. The first and third images are multi-colour images, where the layers are colour-coded to differentiate the state of the areas: red for data from 1993, green from 1998, and blue from 2005. These colours indicate where deforestation has occurred during these years. The second and fourth images are collages of the images used to create the respective multi-temporal images.
