Key technologies on rapid web publication of spatial data

Abstract

In this paper, we present the theory and methods which implement the rapid web publication of spatial data based on WebGIS system using ArcGIS and other open-source 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 further to achieve the organization and management. The key technologies include coordinate conversion, map tiles generation based on Java program, storage strategy based on five-level directory, and management platform based on web application. 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.
