目前，大部分的空间数据共享还是基于地理元数据的传统共享模式，而且多以文本或者简单缩略图的形式提供海量多源空间数据的共享，这在应用上，一方面存在着一些不足；另一方面，随着网络的普及，公众对多源空间数据的网络统一集成显示与可视化共享提出了迫切需求。基于此，在深入分析了多源空间数据集成及可视化共享需求的基础上，针对海岸带多源空间数据的特性，研究了海岸带多源空间数据网络集成显示、矢量和栅格的图形交互查询、可视化信息下载的技术方法，并以“台海区域多源空间数据集成共享系统”为例，介绍了基于ArcIMS的海岸带多源空间数据集成显示与信息服务的具体实现过程。实践证明，这种海岸带多源空间数据集成显示与可视化共享技术，能以“所见即所得”的方式较好地满足用户的网络共享需求。

Most of spatial data sharing platforms at present are still based on traditional geographic metadata mode，mostly in the format of simple text or brief figure; On the other hand, with the popularization of internet, integrating and visualization sharing of multi-source spatial data unified on internet are urgently required. On the basis of problems fore-mentioned, firstly, in this paper we analyzed the requirement of integrating and visualization sharing of multi-source spatial data. Then，aiming at the characteristics of coastal zone multi-source spatial data,we discussed the methods of integrating coastal zone multi-source spatial data unified on internet, the interactive querying of vector and raster graphics, and downloading multi-source spatial data visually. Finally,we took “Taiwan Strait area multi-source spatial data integration sharing system” as a case study, introduced the detailed realization process of integration and information services of multi-source spatial data in coastal zone based on ArcIMS. It shows that the technologies for the integrating and visualization sharing of multi-source spatial data in coastal zone provided in this paper, can satisfy users sharing requirement on internet in a way of “What you see, what you get”.
