The invention discloses open intelligent earth system architecture and an implementing method thereof, and relates to the field of geospatial information. The system can be logically divided into a physical layer, a data layer, a functional layer, an application layer and a management and support layer, and comprises a data acquisition system, a data communication system, a data integration system, a data processing system and an intelligent service system. The implementing method for the open intelligent earth system architecture comprises the following steps of: acquiring the data and information of the earth and the related phenomena thereof by using various sensors or detectors; integrating and managing the data by using communication technology and cloud computing technology; identifying, processing, extracting and mining the data by adopting pattern recognition, artificial intelligence and various algorithmic models to acquire the required knowledge; and transforming the knowledge into various service modes and products meeting the requirements so as to provide intelligent service. The invention is characterized by applying sensor network technology, internet of things technology, the cloud computing technology and data mining technology in the field of intelligent systems to build the open intelligent earth system architecture, and providing the implementing method for the open intelligent earth system architecture.
