地图数据库图形输出中要素关系处理

HANDLING OF FEATURES'REALATIONSHIPS IN THEPROCESS OF THE GRAPHIC OUTPUT OFCARTOGRAPHIC DATA BASE

本文提出了利用地图数据库的检索功能，建立要素图形输出的定量优先级、地理要素图形大小，及基于地图数据库的图形冲突位置的探测方法，并将要素图形输出中的关系划分为五种进行分别处理。

: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.
