[Abstract]:With the rapid development of remote sensing technology, especially the development of satellite sensor, the period of obtaining remote sensing image is shorter and shorter, the resolution is higher and higher. On the other hand, the application scope of remote sensing image is more and more extensive, the industry application software presents the diversification development trend. In the application software of remote sensing industry, how to quickly render and browse the massive remote sensing image data is the foundation and key of all visual remote sensing application software. This paper analyzes the current situation of the rapid browsing technology of massive remote sensing images at home and abroad, analyzes and summarizes the shortcomings of the current research results. This paper studies the relevant techniques and methods for effectively processing, loading and rendering mass remote sensing image data in the software system, and also discusses the specific design scheme and implementation process of the system. The following aspects have been completed: (1) the fast reading method of massive remote sensing image data is studied in order to realize the fast loading of remote sensing image data; (2) the fast rendering calculation and display scheme of massive remote sensing image data is studied in order to realize the fast display of remote sensing image data; (3) data caching mechanism and asynchronous cache scheduling strategy are studied to improve the user experience of remote sensing image browsing. (4) combining the framework plug-in mechanism and remote sensing image processing technology, The design scheme and implementation method of the rapid browsing system of massive remote sensing image developed by enterprises are discussed in detail. Through the technical scheme and implementation method studied in this paper, it is applied to the geographic information remote sensing platform, which greatly improves the rendering efficiency of the platform to the massive remote sensing images, and improves the user experience of the remote sensing application software. Improve the efficiency of space and image analysis.
