Google Map或其他遥感图像发布系统发布的遥感图像都是先用遥感图像处理软件进行3波段彩色图像合成后,然后建立金字塔和分块等处理,放在服务器端.用户只能看到合成后的图像信息,其他波段信息无法看到.提出的方法是将多波段遥感图像的每个波段分别处理后,分别放在服务器端,然后根据浏览器端用户的请求,动态选择3个波段的图像数据传输到浏览器端,在浏览器端应用最新的HTML5的功能动态地进行3个波段图像的合成.这样,用户能看到不同波段组合合成后的图像信息.因此,系统能提供给用户更丰富的遥感地物信息,并且能极大地节省在服务器端的存贮空间.
Remote sensing images released by Google Map or other remote sensing image publishing systems are firstly processed by remote sensing image processing software to perform 3-band color image synthesis, then pyramid and block creation are performed on the server side, and the user can only see the synthesized Image information and other band information can not be seen.The proposed method is to separately process each band of multi-band remote sensing images on the server side and then dynamically select the image data of three bands according to the request of the browser end user Transmitted to the browser side, in the browser side of the latest HTML5 features dynamic three-band image synthesis, so that users can see the combination of different bands combined image information.Therefore, the system can provide users with richer Of the remote sensing feature information, and can greatly save on the server side of the storage space.
