| Abstract: | :This paper puts forward a new method which makes full uses of the retrie-val functions of the Cartogaphic Data Base(CDB),creates the quantitative pri-ority levels of the graphic output of features,defines the sizes of the feature gra-phs, and provides detecting method of the graphic conflict based on CDB. Inthe procedure of treatment, all relationships of the graphic output are dividedinto five classes which are will be treated separately. All the algorithms pro-cessing the relationships are introduced in detail in this paper. Finally, it ana-lyses the preliminary experimental result, and puts forward some other metho-ds solving this questions. |
