Abstract :
Unsupervised change detection analysis of multitemporal Landsat imagery of the Chernobyl exclusion zone shows that the extent of the impact of the accident at the Chernobyl nuclear power station on the regional land cover was limited and that the long-term effect is dominated by natural ´greening´ of the area.
