摘　　要：Distributed/parallel-processing system like sun grid engine(SGE) that utilizes multiple nodes/cores is proposed for the faster processing of large sized satellite image data. After verification, distributed process environment for pre-processing performance can be improved by up to 560.65% from single processing system. Through this, analysis performance in various fields can be improved, and moreover, near-real time service can be achieved in near future.Distributed/parallel-processing system like sun grid engine（SGE） that utilizes multiple nodes/cores is proposed for the faster processing of large sized satellite image data.
