Abstract :
Since MODIS data have the feature of huge capacity and multi-spectrum, it needs too much time and frequent I/O operations to correct them by RS software. This paper proposes a parallel algorithm for MODIS Data based on triangulation network. The input images are divided into several pieces and each CPU processes a piece independently. By implementing the algorithm on a cluster system, the results show that, this parallel algorithm improves the efficiency of geometrical correction greatly.
