The Research Of Lunar Geological Spatial Data Management System

In recent years,our country has made great progress in the research on the moon.Through the Chang'e project,a large number of lunar scientific data have been acquired and mastered,and the research of "lunar geological spatial data management system" is carried out to establish a practical and innovative distributed integrated management scheme for lunar scientific data,and to establish a unified data management system.Through the construction of the lunar geological spatial data management system,the moon data and its affiliated geological data can be collected and managed synthetically.The lunar geological information can be easily accessed,edited,inquired and statistics,and it can be analyzed in various forms.This study establishes a unified multi data standard for the moon,establishes a standardized and unified warehouse rule,forms a standardized data management.Moreover it provides a comprehensive knowledge base of a variety of reference materials,and gradually realizes collaborative mapping,distribution management and integration sharing.This study can provide auxiliary decision-making for subsequent research.The system also adds 3D functions to various analysis to improve the visibility and practicability of the system.In order to enhance the visualization of the information management of the lunar surface,the technology of information visualization is adopted,and in order to realize the rapid transfer and full sharing of the data,the contemporary advanced network technology should be used.In order to realize these functions,we need to establish four functional subsystems,namely,basic data service system,mapping system,document sample achievement management system,and 3D sharing platform of the moon.This paper is a comprehensive introduction to the research results of the lunar geological spatial data management system.The overall framework of the system,the key technology of the system implementation,the functions and the implementation plan of each subsystem are introduced in the chapters.
