Abstract
The paper researched and realized the initiative message transmission mechanism of WEBGIS server based on the N layer architecture of Internet. According to WEBGIS application long business operation as well as server information visualized in client side in real-time features, this article uses the Socket communication and the client side with JAVA Applet to realize that the WEB server can send message initiative to the client. It comes up and realizes a concrete plan of initiative transmission mechanism in WEBGIS. We run the realization plan based on Winsock through the project practice of Guangzhou cable TV network security monitoring and alarm system. The system operation has been verified in system running. The combination of this mechanism with conventional WEBGIS can greatly improve the performance and the usability of WEBGIS.
Highlights
With the development of Internet technology and the rising demand of GIS, using Internet publish spatial data on the Web and providing spatial data browsing, query and analysis capabilities have become the trend of GIS development

Summary
With the development of Internet technology and the rising demand of GIS, using Internet publish spatial data on the Web and providing spatial data browsing, query and analysis capabilities have become the trend of GIS development. WEBGIS and controlling system, mobile location service and real time information exchange are more and more closely connected. It is estimated that 80% information are connected with location. It often costs lots of effort in searching some person or place. Location information has become very important for people. With the development of industrial automation, WEBGIS is used in real time controlling system, which challenges traditional information exchange methods and proposes higher demands of real-time, security, and timeliness of information exchange in WEBGIS
