中文摘要：

利用AdobeFlashBuilder（Flex编译软件）设计实现基于Flex的城市基础地理数据发布系统。充分利用Flex自身组件的特性，与地图元素相结合，完成城市地图的绘制、浏览、GIS功能等的设计，成功将原始城市地理数据发布．利用FlexRIA实现Web城市地理数据发布系统具有表现力强、交互性强等诸多优势。不使用API的基于底层的开发也使系统更具原创性、数据通用性，同时也增加了程序的可拓展性。

英文摘要：

The paper is about using Adobe Flash Builder（ Flex compiled software）to design and achieve a paragraph of city basic geographic data release system based on Flex. The release system do not use any present Web map APIs （ application programming interface）. It begins with the basic development, and releases the city geographic data success- fully by making full use of the characteristics of Flex＇ s components and being combined with the map elements, to com- plete city map drawing,browsing, GIS functions＇ design. The research shows that the Flex RIA realize to Web city geo- graphic data release system has many advantages such as strong expressiveness, strong interactivity and so on. The sys- tem, do not use the APIs and begin with the basic development, which is more originality, data generally, and also in- creased the program expanding. This paper＇ s research has a reference value of Flex RIA applied to the geographic data release system by Web map.
