MODIS Image Based Computation of Vegetation Indices in MedioGRID Architecture

Abstract

The paper presents MedioGRID platform as a general-purpose solution for satellite image processing on grid architecture, and exemplifies by the Greenland application the computation of vegetation indices based on MODIS satellite images. The application provides efficient and simple user interactivity through the graphical user interface. The user selects the satellite images by time and geographical area, and specifies the particular processing operations. The performance of the grid application architecture is evaluated considering a few variables such as number of jobs, number of workers and dimension of satellite images
