Background

Along with the terrestrial space information technology development, on the international resources environmental science domain research technique and the method are experiencing the comprehensive renewal and the transformation.In particular take US as representative's world main developed country, through the large-scale resources environment database construction and the terrestrial space information technology application, enable the resources environmental science to obtain the considerable development.
In my courtyard resources environmental science domain knowledge innovation scientific research practice, has obtained the land surface layer systems science methodology important gradualness research results, has explored a use space information analysis method, the long-term field survey data, the laboratory simulation and the physics and chemistry analysis data, the humanities economical real diagnosis investigation data and the remote sensing the research technique which unifies to the place observation data, and obtains the application in the land surface layer systems science research, promoted the land surface layer systems science discipline construction. At the same time, my courtyard initially has already formed macroscopic and the microscopic resources environmental science data sequence, but because the resources environmental science data disperses in each research institute, any research institute all with difficulty carries on the integration and the system administration under the present system to these data, thus has not formed a perfect series data production system and the value research environment, urgent needs to establish by the Chinese Academy of Science direct leadership under, together participates in the resources environmental science data integration, the derivation, sharing and the value simulation platform by the correlation research institute, the advancement knowledge innovation project further development.
In order to deepen the land surface layer systems science methodology the knowledge innovation achievement, the promotion discipline development, impels the Beijing Earth and the environmental science studies the base construction, the conformity I the courtyard resources environmental science data delivers independently with the system integration superiority, promotes the knowledge innovation ability vigorously, supports the country environmental safety significant decision-making the formulation, as well as the current national territory resources environment plan, the improvement, the forecast and the decision-making to the data message urgent need, on August 2, 2003 the work conference authorized to establish a new Academia SINICA knowledge innovation project to study the unit - - Data Center for  Resources and Environmental Sciences Chinese Academy of Sciences
Establishes the illegal person to study the unit the resources environmental science data central, is my courtyard resources environmental science data realization integration, sharing, the increment important measure.The resources environmental science data central passes “RESDC-HAEDQUARTERS” and 9 “RESDC-BRANCH” the network architecture system the resources environmental science data correlation main research institute to form a scientific data to integrate and to share the platform. Resources environmental science data central besides data sharing, but also through to the scientific data metasynthesis, the knowledge excavation and so on, delivers the data and the National Correlation Department data independently to my courtyard carries on the scientific retreatment, the promotion scientific data value, forms has the higher value new scientific data pool.
This realm explores the mechanism of geo-information, data cognizance and collection, geo-information Tupu, map language and map generalization, as well as the development of theories, methodologies and applications of integrated cartographic system with multi-dimensional dynamic visualization and intelligentization. It also develops micro and macro data integration based upon the geo-information conversion. In addition, great efforts are devoted to the research of geographic information technology for data-software-model-network integration as well as the development of databases including not only the national and global resources and environment information but also society, economy and population data. In order to construct the technology platform and data platform for the information systems needed in the study of national resources and environmental and global changes, time-space systematism and standardization for these databases have been made. These studies will not only serve well for the theoretical and methodological innovation in the development of geo-information sciences, but also provide the technical support and data, and will further realize the full information sharing, for methodological innovation in the researches of geographical science and resources science. Meanwhile, great achievements have been made in software production, in the development of spatial information bank, and in the transformation of geographic information technologies for practical application.
