| 摘 要： | 实现WebGIS技术的主流方法之一是采用J2EE技术,开源的GeoServer搭建的GIS平台满足J2EE规范,该平台具有成本低廉、良好的扩展性和部署的灵活性等特点。但在面对庞大地图数据、庞大的用户交互时,如果仅仅采用GeoServer作为GIS服务器,势必导致地图数据传输缓慢甚至获取服务出错,本文描述了地图缓存技术在GeoServer中的应用,包括瓦片金字塔的创建、内部原理、发布等关键技术。

| Abstract: | WebGIS technology can be achieved by J2EE technology. Open source GeoServer was built to meet the J2EE specification GIS platform which has a low-cost, good scalability and deployment flexibility and so on. But while facing a huge map data, if GeoServer was taken as the only Geo Server, it inevitably causes the slow map data transmission rate, even map service data transmission error. This paper describes the application of map cache techology, which included of the establishment of the tiles of the pyramid, inner principle and other key technologies in GeoServer. |
