Abstract:

The authors analyzed, at first, the background of the National Physical Atlas Database (NPAD) and its information products, and concluded that NPAD represents China's scientific level, and plus its information products, they showed the integration of the atlas' scientific value and social value. Secondly, the paper analyzed the project's scientific intension, concluded that it represents the transferring from Digital Cartographic Model (DCM) to Digital Landscape Model (DLM), as well as the integration of DCM and DLM. Thirdly, the technical feature of the project was related, i.e., we not only placed emphasis on database development, but also paid attention to information sharing technologies in our project. Fourthly, the paper summarized the total characteristics of the project, that is, the combination of dynamic, multiple scale browsing of spatial-temporal feature and static deep analysis & process, of geo-information. Finally, the authors predicted the prospect of China's National Atlas Series, i.e., to develop and construct National Atlas Information System.

Key words: The National Physical Atlas Database, information product of the Physical Atlas, DCM, DLM, dynamic browsing, static analysis
