| 摘 要： | 地图切片(MapTile)技术是目前大多数电子地图网站、3维地图网站使用的预先生成栅格地图,并由客户端接口呈现出无缝拼接地图的浏览技术。地图以链接图片的方式快速定位,访问速度要快于传统的WebGIS,同时,对地图服务器的负载也相应小一些。本文介绍了地图切片技术的相关步骤并对主流电子地图网站做了分析。笔者利用Flash作为地图客户端开发工具,实现了地图切片的实时加载和不同比例尺的漫游。

| Abstract: | More and more web sites of E-map and 3D-map are using the MapTile technique.The maps that loaded in browser are large numbers of raster image.Using the method,we can browse the maps that connecting seamless by lots of map tiles.Because the web server don't have to render the map real-timely,accessing to the E-map system is much more faster than the traditional WebGIS system. |
