The study of changes detection of land covers in Zagros Mountain,West of Iran
Key pointsThis study was performed using TM & ETM ＋ data taken in 1990 and 2002,in order to investigating the trend and rate of cover degradation in Zagros Mountain,Iran.The study area was located in part of central Zagros Mountain.The supervised classification was performed for the images using ML (maximum likelihood).Ground truth maps were prepared for degradation cover class in 63ha of area and also for forest sparse / non forest classes,in 200 ha of area (3％ of total area) using GPS.Also,the overall accuracy and Kappa were obtained 83.38％ and 53.23％ for classifying forest sparse/non forest classes. With respect to comparison of classified map of 1990 and 2002 datasets,12 year period.The degraded area is calculated on 81.47 ha.The average of degradation per year has been 6.8 ha or 0.1％ of area.
