Automatic Geological Map Generalization for special geobody – A Case Study on Dyke

Li, Wenjing; Li, Siyi; Jia, Hongguo

Dykes are always closely coexisting with ore veins in deposit, they are of great significance in the revelation of regional geology evolution, prosperity of ore prospecting. This paper presents a method for the generalization of dykes as part of automated geological map generalization progress. Based on the principle of good continuation, dykes were amalgamated preliminarily. Then the reserve quota was calculated on the basis of radical law for the editing of dykes. Finally, the outer shape and internal construction of dykes were simplified. The experiment results show that the generalization method can avoid discontinuity as a prerequisite to retaining formation lithology and characteristics of geological structure. This method offers a new perspective for dealing with exceptional geographic elements while generalizing a geologic map.
