Grid Based Processing of Satellite Images in GreenLand Platform

Geographical Information System (GIS) applications that process large amount of data require intensive usage of hardware capabilities provided by distributed platforms, such as the Grid infrastructure. Due to the constant demand of data availability and data sharing, without concerning its format and size, a new software solution is needed. GreenLand is a system capable to provide such a solution, based on its constituent modules: GreenLandGUI, gProcess, ESIP, WorkflowEditor, and OperatorEditor. This paper highlights each of them and how they interact in order to create a platform capable of fetching, processing, and visualizing large amount of data exposed in a uniform and standardized manner.
