Video digitization of aerial photographs for measurement of wind erosion damage on converted rangeland

, : Video digitization of aerial photographs for measurement of wind erosion damage on converted rangeland. Photogrammetric Engineering and Remote Sensing 52(3): 373-377

A method for measuring the area of wind erosion damage on rangeland converted to farmland was developed. The selected study area consisted of 7150 ha of cotton that was rangeland before 1954. A video graphics microcomputer system enhanced and digitized aerial photographs to measure the area of wind erosion and the proportion of cotton cover crop on selected farms. An av. of 23% of the total study area showed signs of wind erosion damage.
