Integration and update of China’s map data at the National Seismic Network Center
摘要
Abstract
This paper gives a brief introduction to the first complete integration and up-date of China’s nationwide map data after “the Tenth Five-Year Plan Proj ect”at the China National Seismic Network Center (CNSNC).The fundamental geographic data of the 2008 global version (1∶1 million)is used as the primary data source in the integration and update, with the supplement data of the 2002 national version in the same scale.After the analysis, the above data is converted, j ointed and topographically processed. The administrative boundaries,residential area are also complemented.By integrating and updating work,the continuous and coincident graphical data is obtained and the updated map data can meet the demands for seismic monitoring at the CNSNC,and lay a foundation for the further work as well.关键词
