The land cover classification was carried out by supervised maximum likelihood method, using Landsat-TM data. Training area selection is the most important thing. Since histograms of the same class sampling points are different, we select many training areas for each class. Also the selection of training area was changed to approach classified land cover area to statistics of agriculture and forestry. The 85% of classification from the Landsat TM data in 1987 agreed with the measurements.
