基于MAPGIS工作流的矢量数据库建库方案

矢量数据库是国家基础地理信息系统的重要组成部分,目前已在国家许多部门得到广泛应用。传统的矢量数据库建库方式都是面向过程的,建库流程单一且操作步骤繁琐,矢量地形数据库的数据量庞大、数据内容复杂,建库过程相当的缓慢。为了克服传统建库方式的缺陷,本文引入了工作流技术,将建库过程抽象为几个工作流的节点,通过界面配置获取节点参数,通过工作流引擎控制建库过程,使建库流程可搭建可控制,以达到自动化建库的目标。通过国家1∶250 000矢量地形数据库建库实例证明了本方案的可行性。

Vector database establishment scheme based on map GIS workflow

The vector database is an important part of the national basic geographic information system.The traditional method of vector database establishment is process-oriented,and it has fixed and complicated steps to establish a vector database.Besides the data count is huge and the structure of the vector data is complex,so it costs a lot of time to establish a vector database.In order to accomplish the Automation of the database establishment,a new method with workflow technology is designed.A work flow model b...
