Realtime Remote Sensing Image Publishing System Based on COG Technology

Abstract

In order to solve the problem that the image pre-slice method cannot meet the needs of disaster emergency management and instant release, this paper designs a method for remote sensing image segmentation optimization and rapid release based on Cloud Optimized GeoTIFF (COG) technology and establishes an image real-time release system to achieve multi-band remote sensing image processing, rapid release in the background and front-end combination application. The experiment shows that the rapid release technology of remote sensing image based on COG technology shortens the access time of image data through the efficient data stream transmission, and realizes the large-scale rapid release, which can meet the needs of emergency release of remote sensing image.
