异构矢量数据映射工具的设计与实现

The design and implementation of heterogeneous vector data mapping tool

针对异构矢量数据相互转换的问题,文中设计和实现一种异构矢量数据映射工具。在分析异构矢量数据间各种差异的基础上,进行数据映射工具关键环节设计,并利用ArcGIS Engine相关组件,在Visual Studio开发环境下进行工具实现,将所开发的工具应用于陕西省基础地理信息数据与天地图框架数据之间的数据转换工作。实践结果表明,设计与实现的异构矢量数据映射工具,能够减少数据转换中的人工重复作业,转换后的数据结构正确、内容完整,在保证数据转换质量的同时,有效提升了数据转换效率。

Aiming at the problem of mutual transformation of heterogeneous vector data,this paper designs and implements a heterogeneous vector data mapping tool.Based on the analysis of various differences between heterogeneous vector data,the key links of the data mapping tool are designed,and the tools of ArcGIS Engine are used to implement the tools in the Visual Studio development environment.The developed tools are applied to the data conversion between the basic geographic information data and the data of the sky map framework of Shaanxi Province.The practical result shows that the heterogeneous vector data mapping tool designed and implemented in this paper can reduce manual repetitive work in data conversion.The converted data structure is correct and the content is complete.It can effectively improve the efficiency of data conversion while guaranteeing the quality of data conversion.
