During 1992—1995

Chinese Academy of Sciences （CAS） and The Ministry of Agriculture organized the project named "National Resources and Environment Remote Sensing Macroinvestigation and Dynamic Study". After three years work

by setting "swift

advanced techniques

new remote sensing data and dynamic study" as the characteristics

the project formed complete methodology; accomplished national resources and environment combined-classification investigation; established "The National Resources and Environment Database"

and developed the resources and environment remote sensing dynamic study in typical areas. The success of the project proved the feasibility of developing national resources and environment swift investigation and dynamic monitoring by using remote sensing and GIS techniques. An operating remote sensing-GIS system can provide information of resources and environment swiftly

macroscopically

objectively

and accurately.
