摘　　要：Digital Earth is an important field of information technology and a research frontier of geosciences in the 21st century.So far,the Grid computing technique is one of the best solutions for Digital Earth infrastructure.Digital Earth can only be realised through the interaction of people,heterogeneous computing resources,information systems,and instruments,all of which are geographically and organisationally dispersed.Earth observation(EO)includes information acquisition,processing and applications.Information acquisition provides a vast amount of spatial data for building the fabric resource infrastructure.Information processing means that spatial information processing middleware is used with large amounts of secure Grid computing resources for real-time processing of all kinds of spatial data.We are currently working on the development of coremiddleware for EO data processing and applications for the Digital Earth Prototype System,which is available in the Institute of Remote Sensing Applications(IRSA),Chinese Academy of Sciences(CAS)The further results will be available soon.
