Most of the GIS platforms are used to display the latest map and not preserve history geographic data.History Event GIS platform is designed to preserve history geography data and the present geographic information.The history developing process can be queried and displayed.But how to preserve all the huge GIS data is a difficult problem.The key problem is how to build the spatio-temporal data model of GIS in History Platform.A good data model not only can reduce storage space,but also can display better space image.In recently years,there are many research work about spatio-temporal data model.But none of mature GIS platform appears.This research work on the spatio-temporal data model in the history event GIS platform will bring significant progress in this field.
