In 1926 a Polish scientist, Stanislaw Bac initiated the first quantitative and comparative study of the soil loss at Dublany s tested Estate near Lvov, Ukraine (Experimental Station of the Polytechnic of Lvow). He measured meteorological conditions, soil dynamics ilts the on the slopes, carrying power of the wind and water, soil displacements on the slopes caused by ploughing. Comparing contour lines > of the derived from two large-scale (1:2880) maps of his test area prepared in 1882 and in 1922 respectively, the author revealed the changes of the surface of arable fields on loess soils, which took place during 40 years. In 1928, the results of his observations were published in the first Polish scientific paper on soil erosion and conservation strategies. Access to aerial photographs of the Lvov area acquired sary the in 1994 encouraged the author of this work to continue Bac’s researches on the same area, but with the aid of modern geoinformation >viation methods. After field GPS measurements, strip of 3 B&W panchromatic (1:10000 scale) aerial photographs was photogrammetrically nd this processed with satisfactory accuracy (RMSE ca. 0.4 m). Digital terrain model (DTM) and 0.3 meter resolution ortophoto were genera- original ted and then used to calibrate old (1922) maps. After contour lines digitisation the 1922 DTM was generated through the interpolation process. Change detection analysis consisted of the comparison of DTMs from 1922 and 1994. The extent, magnitude and rate of soil erosion were determined. Surface level changes averaged in the in range of +/-3m. Both natural and man-made factors of this state were identified. Furthermore, the quantitative results of photogrammetric measurements were compared with the results based on the one of the most popular soil loss models — USLE (Universal Soil Loss Equation), which was applied to the same area. y data | Geod. 1.

Its most often occuring evidences are brighter zones on a hill slopes (Fig. 2). This phenomena, named by Zolcinski as ,,dead plots" is caused by low soil humus content level. Soil humus is deposited at the foot of the slope and it can be clearly seen on National aerial photographs as dark zones (Fig. 3) Access to the aerial photographs of this special test-site acquired within the scope of the Open Sky Treaty in 1994 encouraged the ; ee uot d Chrabeéee 2 el. 815 me Figure 1.
