A philosophical and technical comparison between providing good opportunities for the users of virtual Legion and Globus is done [15]. Performance of Alchemi and organizations forming a Grid for coordinated resource sharing Globus is compared [10]. Similarities and differences between and problem sharing. Much Grid middleware software exists for Grid computing and such distributed computing systems as implementing a Grid framework. Apart from many application P2P, areas of Grid Computing, Geographic Information System has CORBA, Cluster Com puting, and DCE are explained [2]. been an emerging application area for Grid Technology in recent time. In this paper, the developments in the field of Grid-GIS are With the help of Grid middleware sharing of all kinds of discussed after a brief overview of Grid Computing and GIS resources, including data resources, computing resources, separately. Some observations are also discussed in the storage resources, information resources, knowledge concluding section of the paper. resources, etc. has become possible. This paper describes the evolution of Grid-GIS systems. Index Terms — Grid Computing, GIS, Web-GIS and Grid-GIS Section II describes the Grid Computing Technology and the underlying architecture. Section III describes the Geographic Information System (GIS), accessing data from GIS databases, I. INTRODUCTION problems of GIS databases such as heterogeneity and interoperability, and spatial data handling language, N earlier days when mainframe computers were used for Geographic Markup Language (GML).
