基于Internet/Intranet的气象卫星资料检索系统

描述一个国家级的气象卫星资料Web检索系统的方案设计和实现。该方案采用Web浏览器／Web服务器／数据库服务器三层体系结构，实现并发布了基于Internet／Intranet的气象卫星资料编目检索业务系统。检索系统建立在HP-UX操作系统上，以Netscape Enterprise Server为Web服务器，Netscape公司的Live Wire为中间件，Sybase为数据库管理系统。检索系统重点突破了可视化地图框定检索关键技术，实现了快视图浏览、编目检索、各类客户端可控制的图像动画等功能。

Meteorological Satellite Data Retrieval System Based on Internet/Intranet

The main content of this treatise is the design and implementation of the national level Web retrieval system of meteorological satellite data. With three layer system structure-Web browser ,Web server and database server, we implemented and published the Internet/Intranet based retrieval system of data from meteorological satellite. The retrieval system was developed on HP-UX operation system. The Netscape Enterprise Server acts as its Web Server, the LiveWire of Netscape acts as its middleware, and Sybase acts as its DBMS. The breakthrough of the retrieval system is the key technology of visual retrieval with marking on the map. It allows us to make the retrieval condition by dragging the mouse on the map displayed on the user's screen. The retrieval system also implemented the functions of quick-view image browsing, catalogue retrieval and client-side manipulated image animation, etc.
