An instant messaging system based on Google Map

Google Map is widely used as a platform for a number of applications because of providing the public satellite maps all over the world, but it is hard for user to add vivid interactive applications on website based on Google Map (GM). The reason is that GM can not provide many features of API while allows the application to mix its content with it before. In order to interact with GM instantly and display the application content dynamically, an instant messaging system designed by flex is described in this paper. A travel application is also implemented and embeds in a micro-blog system, including the server part and client part. The application shows that our framework can display dynamic map content and has better ability than the application which interacts with GM by JavaScript.
