In spatial information data grid, the difference among metadata makes it difficult to re-organize data and share them. In this paper, a way named metadata adapter is proposed, to interpreter original metadata with different syntax and semantic rules to required metadata so that they can be organized as a distributed, heterogeneous, inherent features based, and one-stop served virtual remote sensing data catalogue. Based on the metadata adapter, SIG can build up a powerful and flexible data grid for spatial information applications. The experience of ldquoremote sensing data distribution system for WenChuan earthquake rescuingrdquo amazingly quick founding shows that metadata adapter is a powerful and economical way to solve the problem of metadata difference in spatial information data grid.
