spatial data warehouse (SDW) is a convenient way for managing and distributing information among public. In this paper

the society and institutional context of building spatial data warehouse is given

that is followed by the discussing of strategies used when constructing SDW and architecture of SDW. Then related construction steps of SDW are introduced in detail. Based on these theories discussed

a prototype of SDW is designed and implemented to display how to build a SDW.
