Photomorphic Units Map Derived from Processing Satellite Images as a Model in Providing Erosion Types Maps

A. Mohammadi Torkasvand

Abstract:
In this study, the possibility using ETM+ satellite images for providing erosion types maps was investigated. With regards to the lack of visual distinction of surface, rill and small gully erosions on the satellite image after processing, photomorphic units with attention to color, tone, texture, drainage pattern and other image characteristics, were differentiated on color composite by the screen digitizing methods. Photomorphic units map as a model was crossed by ground truth maps of surface, rill and gully erosion; and erosion features map. Results indicated that the greatest accuracy and precision of model is related to providing gully erosion map, although it also is suitable in providing surface and rill erosion maps.
