面向e-GeoScience的地学数据共享研究进展

在总结比较国内外e-GeoScience研究进展的基础上,介绍了中国科学院地理科学与资源研究所自20世纪80年代以来开展的相关工作。提出了按“圈层—学科—数据类别”三级模式的地球系统科学数据分类体系,以主体数据库为核心,初步构建了“主体数据库—数据资源点”为支撑的地球系统科学数据资源体系。在J2EE环境下,采用Web Services、地理信息等技术开发了地球系统科学数据共享平台。最后,探讨了e-GeoScience未来的研究方向。

The Research Progress in Geo-data Sharing Based on e-GeoScience

Based on the summarization and comparison of the e-Geoscience research progress in both domestic and international levels,this paper introduced the relevant work conducted by IGSNRR(Institute of Geographical Sciences and Natural Resources Research,CAS) since the 1980s.Classification architecture of three levels of Earth System Science data was put forward,i.e."Earth Circle,Discipline,and Data Class".The System of Earth System science data resources has subject databases as the core elements,with data source points as supporting elements.Under the development environment of J2EE,Earth System science data platform has been developed by employing Web Service,GIS and other technologies.In the end,the author discussed the future research frontier of e-GeoScience.
