天地图·福建数据融合技术与方法

Based on Map World Fujian Data Fusion Techniques and Approaches

通过对福建省1∶10 000核心要素与天地图国家主节点数据研究,分析天地图国家主节点与福建省基础地理信息数据现状,结合天地图数据融合的技术要求,充分考虑融合与共享,设计了福建省1∶10 000核心要素与国家天地图数据融合的总体流程,并分要素阐述处理要求,有效解决了多源多尺度异构数据的融合问题,该技术已经在天地图·福建数据融合项目中得到了应用,为省级基础地理信息数据参与国家天地图数据融合提供了参考。

This article has analyzied the data status of the master node map world countries and the fujian province basic geographic information through to 1：10 000 core dements of Fujian province with tile master node map world countries data research. The overall process of 1 ： 1 0 000 core elements of Fujian province in fusion with the map world countries was designed by combined with the technological requirement of data fusion of world map. The data fusion and sharing were fully considered, and the processing requirements were elaborated with each element. This processing has effectively solved the data fusion problems of the different data source, different scale and different data model. This technology has been in application in Fujian province map world project. The application of data fusion has provided the reference for the provincial basic geographic information data to participate in the country map data fusion.
