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 elements of Fujian province with the 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 tech-nological 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, differ-ent 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.
