     China Institute of Geo-Environment Monitoring is building a national-level geological environment information platform, as an important part of a national data center aiming to collect, integrate and analyze the national geological environment data characterized by its huge size, multi-source, both structured and unstructured storage. In order to extract valuable information from the data center rapidly, a data warehouse based on the concept of big data is applied to integrate operational data into data center for professional analysis. The system running results show that the data warehouse, which consists of 8 data marts （geo-hazard prevention, underground water monitoring and protection, mining geology environment and etc） and each of them can be divided successively into various subjects and sub-subjects by loading data into star schema in multiple dimensions, different levels of granularities and various perspectives, can provide multi-dimensional data analysis and support decision-making, and therefore presents a new strategy on discovering valuable information from geo-environmental data.
