Association Rule Mining of Lithology Analysis in Three Gorges

Three Gorges are the south area which is thickly covered by soil and flourish vegetation and the lithology analysis is very difficult. There is also no mature method on this aspect. Three Gorges possess the characters of complicated terrain, frequent geologic disasters and full-grown vegetation and soil, so it is very important to make lithology analysis in the area. In the paper we made analysis of lithology with remote sensing images aiming at the area of Three Gorges, adopted the idea of oriented-object, built three sorts of guideline sets of spectrum, texture and vegetation covering, made quantification of the guideline sets and based on the algorithm of concept grid mined the associated rules of the lithology in the stratums of Three Gorges: Jia Second and Third Sections Jia Ling River Group T₁j² and T₁j³, Ba First and Second Sections Ba Dong GroupT₂b¹ and T₂b², and Da Ye Group T₁d.
