Abstract
A geospatial Data Clearinghouse is a system to provide information about a geospatial data. The aim of this systemis to promote to share geospatial data among users and researchers effectively. In this paper, we focus on the architecture of clearinghouse. First, we categorize some architecture in point of management type of some clearing node. Second, we propose Node Information eXchanger (NIX) to realize effective information retrieval under the distributed network. Some experimental results show some advantages of our proposed system.
