摘要
根据Flex具有的矢量化图形处理技术、图形绘制功能和异步数据交换技术,研究和开发基于Flex的WebGIS电子地图系统结构,分析Flex把WebGIS数据从页面剥离,并通过Socket端口进行传输等Flex异步传输的关键技术,阐述该结构的优势,解决传统电子地图传输的延时问题和用户交互体验的情况。
According to the vector graphics technology, flexible graphics rendering capabilities and asynchronous data exchange technology of flex, develops the system architecture of WebGIS network map based on Flex and analyses the key technology of Flex asynchronous transfer that the Flex gets WebGIS data from Web page and transports it through Socket port, and describes advantages of this architecture to solve the traditional problem of transmission delay and user interactive experience of the situation.
