Evolution of Grid-GIS Systems
Grid is the collection of heterogeneous resources, providing good opportunities for the users of virtual organizations forming a Grid for coordinated resource sharing and problem sharing. Much Grid middleware software exists for implementing a Grid framework. Apart from many application areas of Grid Computing, Geographic Information System has been an emerging application area for Grid Technology in recent time. In this paper, the developments in the field of Grid-GIS are discussed after a brief overview of Grid Computing and GIS separately. Some observations are also discussed in the concluding section of the paper.
