The idea of geo-information Tupu is reviewed and summarized by reading and analyzing the theses published by Academician of Chinese Academy of Sciences, Prof. Chen Shupeng in this paper, which come from his scientific probe into geo-system. Geo-information Tupu is the result of combination of Geo-Tupu and information technology, which aims at discovering spatial and temporal knowledge and rule of geo-science, and can provide service to social and economic construction. Geo-information Tupu is classified into different types for each branch of geo-science and each industry according to its research object, and it is also classified into symptom Tupu, diagnosisTupu and realization Tupu according to its function. Prof. Chen developed the technology method for generating geo-information Tupu, proposed the workflow of geo-information Tupu, promoted the application of geo-information Tupu to the economic and social development. Prof. Chen indicated innovation directions of geo-information Tupu development which include innovation of technology and method of obtaining geo-science big data, improvement of intelligent and automatic level of generating geo-information Tupu, and enhancement of the wide and deep application of geo-information Tupu in social and economic construction. Prof. Chen pointed out grid map is important base of geo-information Tupu. The idea of geo-information Tupu proposed by Prof. Chen still has important guidance value in promoting the advance of geo-information science and meeting the major strategic needs of our country. The exploratory practice and results under the guidance of the idea of geo-information Tupu proposed by Prof. Chen were concluded here. The thematic information extraction technology based on knowledge discovery and the fine geo-surface element acquisition technology based on multi-data and multi-knowledge cooperation have been developed in recent years, which improves the automation level and efficiency of obtaining geo-science elements such as waterbody, settlements, green vegetation cover, snow cover, vegetation and landuse types in detail. The study and application of spatio-temporal change information Tupu have been broaden. The intelligent level and efficiency of generating the spatio-temporal change Tupu have been improved. The application of Geo-information Tupuin in social and economic development, ecological construction, environmental protection and disaster risk prevention and control has shown great prospects in recent years. Finally, in order to meet the major strategic needs of jointly building a global community with a shared future for mankind and the internationalization of geo-science in the new era, this paper puts forward the research on the key technologies and its applications of the global geo-science information Tupu, so that the large knowledge are intelligently and automatically discovered from big data of the geo-system through big observation, and the large knowledge is broadly applied to every aspect and every place through internet, which will support the modernization of the governance system and ability of the geo-surface system, and enhance the level and ability of geo-sciences to serve economic and social development, and highlight the characteristics and advantages of the geoscience.
