The design of efficient distributed applications depends on the coordinate use of different API (Application Programming Interface) like MPI and NT API's. In fact, a particular optimized code can be reused in many other applications reducing the cost of its design by means of a set of libraries. Distributed processing is applied in remote sensing in order to reduce spatial or temporal cost using the message passing paradigm. In this paper, we present a workbench called DIPORSI, developed to provide a framework for the distributed processing of Landsat images using a cluster of NT workstations. Our application is based on a NT implementation (WMPI) of the MPI standard. Thus, the large amount of time required by the sequential processes drops when the parallel processing is used. Moreover, we have obtained a reduction of computation time over the 400% for large size images and a moderate number of parallel nodes. Our results confirm that cluster computing is a cost/performance effective solution to the remotely sensed image processing.
