Research on Archive Method of Massive Remote Sensing Data

Archived data play a crucial role in remote sensing data applications. These data are extremely unique. Their volume is usually considerably large and need to be preserved for a long time or even permanently. With the rapid development of remote sensing technology in recent years, the resolution and sampling rate of remote sensing downlink data are becoming higher and higher. How to archive these massive data effectively has become a critical issue for all the space organizations. In this paper, integrating with the characteristics of archive data, the archive procedure and its current status are introduced and analyzed. Then according to the new development of computer technology and data storage technology, the possible trends of massive remote sensing data archive method are discussed.
