Abstract:

 With the rapid development of spatial information technology, earth science information technology and GIS technology, a spatial database management WebGIS system based on lunar multisource geologic material (2D and 3D) is established with QT and Open GRL technology. The system contains three subsystems, the 2D research result managing subsystem,  the research result publishing subsystem and  the 3D lunar research data subsystem, which can improve the utilizing efficiency of lunar information. The latest research results of the Chinese lunar exploration program, including topography, rock, soil, resources, environment and other relevant data, as well as foreign research documents, articles and reports, are integrated to establish this Chinese first lunar geologic data information system. The system contains management functions (data management, data consolidation and integration) and service functions for research and decisionmaking. It can realize classification management, rapid retrieval and online query, in addition, it has a strong comprehensive data analysis capability and provides a strong support for Chinese lunar exploration program.
