Geo-Info-TUPU was put forward firstly by a Chinese scientist during the 1990s. Based on plenty of materials, we concluded that Geo-Info-TUPU is resulted from the developments of the subjects and technologies including cartography, geo-info sciences and "3S" , synchronously influenced by the combination of the imagination and the abstract thinking in the geography science. Based on the analysis of the Geo-Info-TUPU' s development process, we expatiated on the theories of the Geo-Info-TUPU, including the basic conception and character, research contents and objects, and the significance of the Geo-Info-TUPU, finally the prospects of the Geo-Info-TUPU was discussed.
