摘要: 针对传统网络地理信息系统(WebGIS)响应慢、交互性和可扩展性差等问题,提出了基于Flex的应急WebGIS架构.架构采用Flex和Java语言提高了系统的移植性,服务端采用AMF协议提高了传输和响应效率,同时架构采用多层模式使得各层之间相互独立.实践证明,该架构满足了应急平台对WebGIS的交互性强、响应速度快、可扩展性强的要求,改善了用户的体验效果.Abstract: Aiming at the problem of traditional Web geographic information system (WebGIS) with slow response,poor interactivity and poor scalability etc,a Flex-based emergency WebGIS system architecture was put forward.The architecture uses Flex and Java language to improve the portability of the system,the server-side uses the AMF protocol to improve the efficiency of the transmission and response,and the architecture uses multi-layer model to make independent of each other between the layers.Practice has proved that the architecture meets the demand such as strong interactivity,fast response and good scalability of WebGIS emergency platform,and greatly improves the efficiency and the user experience effect.
