Abstract:

China has already completed various types of high resolution remote sensing image products for the Antarctic region and the amount of data has increased to TB level. Sharing those image data on the network not only contributes to a better understanding of the Antarctic, but also enhances China's worldwide influence in the Antarctic affairs. This paper describes the design and realization methods of TB Level Antarctic remote sensing image web publishing system based on database and WebGIS platform. It adopts ArcGIS Server as a WebGIS platform for publishing all types of remote sensing images in real time, the users can achieve the remote sensing images on internet environment for positioning and displaying them on an electronic map, this online method can display Antarctica remote sensing image information intuitively and effectively. Aiming at layered, sub-rate and tiered storage of Antarctic images, it designs a convenient vector index file to be used as a bridge between user querying and remote sensing images based on various of ways to query and retrieval data on the Web page combined with images’ meta data information. The WebGIS system will provide a limited sharing of Antarctica remote sensing images and researchers from home and abroad can download them easily if they are authorized.
