With the development of Internet, serving data on the Internet has become one of hotspots for research and application. WebGIS has been applied to serve GIS data on the Internet in GIS field. National Physical Atlas of China (NPAC) is a large-scale synthesizing atlas with great scientific value, serving it on the internet can bring great social benefit, users can query and explore what they need, making thematic map. This paper approaches the implementing way of this system. Firstly, data preparation including data standardization, database reconstruction, data quality control, was expounded. Secondly, the system functions, including data query, dynamic mapping, statistical analysis, etc., was described. Thirdly, the authors discussed the developing technology of the system, including homepage designing, system strategy, browse and server technology, etc. Finally, the future developing direction of the system was foreseen.
Key words： WebGIS; NPAC; spatial data query
