摘要
图形编辑是ＧＩＳ中数据录入、更新及图形输出时的重要环节。本文阐述了地图数据库下图形编辑的原理、方法，ＭＤＢＧＥＳ的构成和功能，并分析了ＭＤＢＧＥＳ的试验结果，按照用户应用程序与ＤＢＭＳ的关系，提出了库函数的建立及其分类方案，以及一整套与地图数据库接口函数的原型。在用户与ＤＢＭＳ的接口规范化方面作了有益探索。此外，本文探讨了符号图形编辑的两种设想。
In GIS,grphic editing is an importont link in datacapturing,updating and outputing.In this thesis.theprinciple,method of graphic editing,the struct andfunction of MDBGES based on map database are stat-ed,and the result of tests is analysed.The project onestablishment and classfication of program library andthe prototype of a set of functions interface with mapdatabase are put forwatd according to the relation ofuser application progtams with DBMS. A useful ex-ploration has been made in making a standard for theinterface of user with DBMS.Two propositions onsymbol graphic editing are discussed.
