In this paper, we present the theory and method to implement the Google Maps-style WebGIS based on ArcGIS software. The original spatial data is configured and landscaped by ArcMap or ArcIMS Author, to generate MXD or AXL files. Subsequently, corresponding map service could be easily created by ArcIMS Administrator. And then, some programming work is carried out to build hierarchical map tiles and to achieve the organization and management requirements. The key technologies include map tiles generation based on Java program, storage strategy based on five-level directory, management platform based on web pages. Finally, the map tiles would be rapidly and seamlessly published in web pages. The method is successfully applied in our research projects, which are demonstrated in the last section of the paper.
