摘　　要：OLE技术在地图制图专题符号生成、插图配置等过程有重要应用。本文针对基于地图文档的地图编辑事务难以支持OLE对象的问题,基于地图文档模型,设计了一种支持OLE对象地图编辑事务模型,实现了地图编辑过程中OLE对象事务管理与处理功能。试验表明,对由外部制图软件工具嵌入的OLE对象内部进行修改后,虽然OLE对象内部数据修改由内部宿主程序完成,但其外部制图软件工具兼容支持了OLE对象编辑事务的回退和重做功能。OLE technology plays an important role in the process of thematic symbol generation and illustration configuration in cartography.In order to solve the problem that it is difficult to support OLE objects in map editing transactions based on map document model,a map editing transaction model supporting OLE object is designed and the management and processing function in map editing is realized.The experiment shows that,after modifying the internal data of OLE objects embedded by external mapping software,although the internal data modification of OLE object is completed by the internal host program,the external cartographic software tools can support the undo and redo functions of OLE object editing transaction.
