Abstract

Today, extensive improvements in fields of soil mapping have increased the purity and ACCURACY OF SOIL MAPs. Usual mapping methods moreover depend on skills and experience of surveyor in identifying and delineating the boundaries, also need the high cost and time consuming that face the soil mapping with restrictions. In this study, aerial photographs with 1/40000 scale were used in order to preparation of the initial interpretive map and determination of sample region. Then, the numbers of 24 profiles were described in determined units. After sampling and necessary physicochemical tests, soil map of Kouhin (Qazvin) was prepared and accuracy of map was calculated in two methods in all levels of taxonomy. The first method was formation of error matrix and calculation of kappa index and second was comparison the geopedological map with described profiles and evaluation the results of each. Then a part of a geopedological map that had overlapping with map prepared by usual method was compared with this map. Results showed the overall accuracy of 67.5, 90.5 and 98.5 percent in levels of family- subgroup and great group- suborder and order of soil for geopedological method respectively.
