Abstract: As an important driving force for development of modern agriculture, agricultural big data can find valuable data, mine hidden information from the massive data base, and grasp the internal connection and regular pattern between data effectively. In many sources of agricultural data, spatial data is still an important component. The theory and technology of spatial data warehouse is the key to develop agricultural big data. Spatial data warehouse is an extension of data warehouse in the space field, it can not only store, organize and manage the agricultural spatial data effectively, but also provide supporting environment for agricultural data analysis. This paper discussed and analyzed the system architecture of agricultural big data, and presented a comprehensive study and analysis from 4 areas: data collection, data integration processing, data analysis and data application, by taking the advantages of spatial data warehouse in spatial data processing and combining the theory of spatial data mining. Finally, this paper provided some suggestions and thinking according to the present status of current studies on agricultural big data in China.

Key words: agriculture big data, spatial data warehouse, spatial data mining
