The visual meteorological observation station system is designed with the B/S structure system and the open source WebGIS layout, developed by using Flex, Jsp and Applet technology. The platform achieved the multi faceted and multi form display of station information, and can fully meet the current needs of the integrated, efficient and accurate management of the meteorology observation system. The application of the platform addresses the problems that the integrated meteorological observation management can not meet the needs of rapid development of meteorological service in recent years. It provides a decision support for equipment protection and station layout optimization, etc., can help improve the management of integrated meteorological observation comprehensively.
