Based on describing the concept, content, types, structure and characteristics of geo-information products, and taking some information products in the database project of the Chinese Academy of Sciences as examples, the authors firstly discussed some theoretic problems, i.e., the value orientation, depth of information process and information propagation potential, best model of geo-information storage and display, as well as the author right, making right and copyright of geo-information products. After that, some technological problems for the development of geo-information products are discussed, including data collection, extraction, derivation and multiple representation of geo-information, and the technologies of geo-information product making, as well as geo-information sharing, communication and application technologies.

Key words: geo-information products, theoretic problems, method and technology
