The maps show the distribution of old forests, swamp forests, grasslands and fields during the 1940’s (left) and 1990’s (right). The interpretation was performed in CIR-photos and black and whites. Within this project a similar study was done in the Länna area. As a result the files delivered show the change in area between the time periods. The Foundation of Uppland was financing the project. (See the same study in the Länna – area with larger images.)
