Abstract: Traditional online mapping service has certain deficiency, which only supports customers to browse and query. In order to achieve the target that client could independently input data, and the server automatically receives spatial information and releases online map, a new method for the construction of spatial information distribution system was proposed is this paper. Based on B/S architecture, this method could get the geographical coordinates automatically by improving the Google Maps API event listener; meanwhile, a self-defined XML file was used to read this kind of record on the server. Then the address resolution functions were used to analyze this kind of XML file and draw the markers on the Google map according to the locations. Through this process the goal of publishing the local data to the Web map was achieved. Based on this method Wuhan University campus navigation system has been developed successfully, which demonstrates the feasibility of this solution.
