Building remote sensing database on grid

a large scale of remote sensing data is obtained every day with the rapid development of remote sensing technology. To store these data will need a large space and to process and analyze these data will need high computational capabilities. Remote sensing data usually are managed by relational database. But with rapid development of the technologies, the data increased in geometric series. Traditional database cannot store and manage these data effectively. Every department will usually build its own database independently. The databases are islands apart from others. The users who want to use the data have to search every database to find the required and copy them to user´s own database. That is time consuming and annoying. Grid is the new technology that provides new ways to solve these problems. Grid integrates the resources and computational capabilities in the Internet or intranet. It provides service-oriented architecture. Bases on grid technology, the new remote sensing database will achieve automatic storage and management. The databases in grid pool combines and acted as one database. It is expressed by services. Users get the results by various services and needn´t copy them to the local database if they require.
