Geo-info-TUPU was raised as a scientific subject when Geo-System Science and Geo-information Science met with challenges and was driven to the innovation in theory, methodology, technology, product as well as application. This paper expounds at first the authors understanding of Geo-info-TUPU, i.e, from Pu (series) to TUPU (graphic series) and then to Geo-TUPU (geo-science map & graphics series), and then induces to Geo-info-TUPU. The definition, feature and key problems of Geo-info-TUPU is also related. Secondly, the authors describe the theoretic bases, standards & models of Geo-info-TUPU, in which the theoretic bases include Geo-science bases, cognition bases and Geo-information mechanism, and Geo-info-TUPU standards & models include its typical style and structure, category criteria, extraction models, modeling standards, integrating & application. Thirdly, the inducing & extracting methods are discussed, with three methods as human manual inducing, GIS & RS tools aided extraction, and automated inducing & extraction being emphasized. These three methods also present Geo-info-TUPU through three levels as primary, medium and higher. Fourthly, the authors explain the development of our knowledge innovation key project, respectively in the spatial dimension of regional Geo-info-TUPU, taking the demographic Info-TUPU and soil erosion Info-TUPU as sample theme, and the dimension of the whole country's Geo-info-TUPU, taking China's hydrology network Info-TUPU and comprehensive landscape Info-TUPU as main theme. Finally, the significance and application method of Geo-info-TUPU for Geo-system-Science and Geo-information Science is concluded.

Key words: Geo-info-TUPU, geo-information science, theory and method
