Research and Implementation on Web Publication of Remote Sensing Images
遥感影像的Web发布研究与实现

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.
