摘要:

随着互联网络的迅猛发展和Web 在网络信息集成中起到越来越大的作用,地理信息系统已经从桌面向网络方向发展,出现了对于WebGIS的研究。针对WebGIS中的影像发布,根据当前影像及internet 的特点,系统地研究了遥感影像Web 发布中的体系结构与技术问题,实现了遥感影像Web 发布系统,并讨论了它与WebGIS的集成。

Research and Implementation on Web Publication of Remote Sensing Images
Abstract:

Lots of remote sensing images have been accumulated in the repository without being efficient used, on the other hand, many application projects called for the share of the remote sensing images. This problem can be resolved by the Web publishing of remote sensing images. In this paper, a systematic research on the web publishing of remote sensing image was conducted, according to the characters of Internet and remote sensing image. A publishing architecture and respective technical problems were given and solved, the remote sensing image publishing system was implemented according to it, the integration of it into the WebGIS was also discussed. The whole publishing procedure is implemented in 5 steps: 1, the user submits the request for the remote sensing image of a certain range in the web browser from the client side. 2, the request is sent to the server and the server queries the database to find the images which are covered in the range. 3, a new image is obtained by combining the images being covered. 4, a size suitable image is obtained by extracting from the new image. 5, the resultant image is sent back to the client and displayed to the user in the web browser. In this way, the user can have access to the remote sensing images by most cut down the net work trans portation.
