摘　　要：提出了一种基于卫星影像数据的海洋WebGIS构建方法,并且依据多级高分辨率卫星影像开发了海洋WebGIS原型系统。对系统的Tiles影像数据、系统框架等几个关键问题进行了重点论述,并给出了系统应用实例,实现了地图放大、缩小、漫游、定位、矢量图层加载及目标区域导航等功能。运行实例表明,依照该框架所开发的系统具有兼容性好、服务器负载小、前台基于标准HTML、支持AJAX且易于结合其他技术等优点。A construction method of marine WebGIS based on the satellite imaging data is proposed. Then, a marine WebGIS prototype system according to the multilevel high resolution satellite images is developed. The Tiles images and framework of the system are mainly discussed. An example is used to illustrate the function of zooming in, zooming out, panning, identifying, adding vector layer and navigation. The result shows that the system has the advantages of good compatibility, small server load, client based on standard HTML, supporting AJAX and easy to be combined with other technologies.
