Abstract: This paper introduces a method of designing a spatial data warehouse based on the technologies of distributed databases, network communication and geographic information system. With the dataset of protected sites in the costal areas of Fujian Province, a distributed spatial data warehouse is built. It arranges data with different dimensions and layers based on administrative and types division as well as regular information of the sites. With an instance of this data warehouse, it successfully creates data cube dynamically according to different OLAP service requests, then accomplishes the OLAP services and returns spatial OLAP results to users.

Key words: distributed spatial data warehouse, data cube, OLAP
