Swedish forestry practice includes a final clear felling after a rotation of up to about 100 years. To follow up on cutting permits, the Swedish Forest Agency (SST) annually maps all new clear felled areas, using satellite image data from the present and the previous year. This practice, carried out by a government agency, also creates a yearly nationwide database with SPOT or similar satellite image data, which has created the base for the above mentioned SACCESS national satellite data archive
