To solve all the problems involved in hydrological data sharing,in this paper,in light of the char-acteristics of hydrological data,a modal of multi dimensions and measures based on the spatial data warehouse is worked out.To describe and manage above-mentioned modal a method named hydrological data unit,u-tilizing the entity,which emphasize the characteristics of time and space and the attributes consisted of hy-drological and sharing information is proposed on the basis of object.Then a perfect project on we hydrologi-cal data sharing constructing of hydrological data unit based on spatial data warehouse and Internet platform(or IHISS) is proposed.
