DEVELOPMENT OF A METHOD TO ESTIMATE THE SPATIAL DISTRIBUTION OF SURFACE SOIL MATERIAL USING DIGITAL AERIAL PHOTOGRAPH

Abstract

To enhance the efficiency of mapping spatial distribution of surface soil material, we have developed and assessed a new mapping method of surface soil material using digital aerial photograph, image analysis and GIS. The method can map the spatial distribution of surface soil material schematically. The method can calculate attributions (Area, edge line) of every surface soil material quantitatively. The method is very useful for understanding relation between spatial distribution of surface soil material and vegetations.
