摘　　要：第三方数据格式DWG搭建了ArcGIS软件和CorelDRAW软件间的桥梁,综合了强大的空间数据处理功能和图形图像设计功能,保证了地图正确的空间信息和完美的平面整饰。但是,经过空间处理的DLG数据以DWG格式导入CorelDRAW进行编辑时,出现了一些亟待解决的问题。针对这些问题,本文基于CorelDRAWⅩ5及其宏编辑器,引用CorelDRAW 15.0 Type Library控件进行了二次开发,实现了制图数据的自动化预处理。The third data format DWG builds the bridge between ArcGIS and CorelDRAW and integrates powerful spatial data processing function and graphics design function,ensuring the correct spatial information and perfect plane decoration of a map.However,as DLG data is imported into CorelDRAW for editing after spatial treatment in the format of DWG,the following problems,which are in urgent need for solving,appear.The first one is the derivation of abnormal elements,which are mainly 0 elements and repetitive elements.Their inspection layer by layer is time-consuming.The second is the breakage of topological relation among elements,especially curves’ connection of mass line data is undoubtedly multifarious.The third is the treatment of redundant elements,the number of whose nodes goes beyond certain value.The symbolization of these elements is of low efficiency and has easy access to causing the abnormal collapse of computer.Aiming at these problems,based on CorelDRAW X5 and its micro editor,the paper cites CorelDRAW 15.0 Type Library and expands secondary development,realizing the automation of mapping data pretreatment.
