Geographic information systems grid

Abstract

GIS Grid (geographic information systems grid) is a combination of geographic information systems and grid technology. Existing non-standardized multi-sources and multi-scales data have a shortage of spatial information shared in either internal and external organizations or departments, especially in national or global applications. It is very important and difficult to store massive spatial data for GIS Grid. And efficient metadata management and data access methods should be studied. At the same time, GIS Grid should provide users with just the services and data they need, without having to install, learn, or pay for any unused functionalities. With the integration of web service and other middleware/toolkit, which support the creation of Grid infrastructures and applications, it is possible to dynamically assemble applications from GIS Grid for use in a variety of client applications. © Springer-Verlag Berlin Heidelberg 2005.
