In the field of smart space, due to the development of technology for remote sensing, monitoring, a vast volume of spatial data is accumulated. However, there have many problems of discovering meaningful knowledge from the spatial data. Consequently, in this paper, a scientific and effective method that spatial information is intelligently processed in smart space by Business Intelligence (BI) was put forward. It describes the development of smart space and the technologies of BI. Then, it presents a general integration mode, which integrates smart space and BI technology.
