摘　　要：矢量地理信息快速制作出版地图问题,始终是数字成图生产的瓶颈。文中提出一种面向矢量一体化处理的全局模型,该模型采用具有亚拓扑特征的超Spaghetti数据结构进行矢量空间数据组织,并在此基础上面向一体化任务所执行的行业标准,进行属性资源模型重构,建立由具有隐含拓扑关系的空间数据和属性参数组成的拓扑信息模型,为实现具有智能化特征的一体化矢量数据处理过程奠定了完备的底层数据基础。基于该矢量一体化全局模型的矢量数字成图方法,可快速获取具有出版效能的矢量地理信息。It is always a bottleneck for digital map producing to use geographic information to speed up making publishable map. The paper puts forward a global model oriented integrating vector processing, which uses super Spaghetti data structure with subtopological features to organize the vector spatial data, follows the industry standards implemented by integrating task to rebuild attitude source model and to build the topological information model composed of attitude parameters and spatial data with hidden topological relationship, establishes the complete bottom level data basis in order to realize integrating vector processing with intelligence. The approach of using vector data to make map, which is based on the above model, can quickly acquire the vector geographic information with publishable efficiency.
