Decentralized GIS Web Services on Grid
Apirak Panatkool, Sitthichai Laoveerakul · 2002
Geographical data is typically generated and stored locally which is then processed by a limited number of specialized computations or services on that site. Nonetheless, to get a global view, one needs to gather information from various locations and process them by using different specific services. Since each location does not contain all the required services, we normally gather data from those locations to be processed on a central server that has all the services. This centralized server paradigm contains some drawbacks such as single point of failure, network congestion, data inconsistency and others. Furthermore, in some real time applications, e.g., traffic control, pollution modeling etc., these problems must be solved.
