A Study of Spatial Data Mining Technique Based on Web

The Web was an information resource with dynamic state, at the same time, As the spatial data complexity and its multifamily of application field, to get implicit and useful knowledge of space, it is necessary to study the integration issues of the spatial data and choose a suitable technology for data processing and analysis. In the paper, the features of spatial datum were analyzed, they were seriate and typical non-structure, and they had the characteristics with timeliness, spatial relativity, difficult to decompose and combination. Based on the analysis of traditional data mining processes and structure systems, a pretty flow and architecture were designed for the data mining of spatial datum; the idea of the data integrated and transformed and designing data warehouse were advanced, also, an implementation method was presented for the key technology.
