摘　　要：Recent developments in space technology and exponential increase in demand of earth observation data from space have generated a requirement of a data processing environment,where users can discover the data and process,based on their requirements.Grid Services for Earth Observation Image Data Processing(GEOID)is proposed with a motivation to cater to future earth observation applications requirements of digital earth.This paper discusses the overview of the GEOID architecture,its deployment scenario,use-cases and simulation results.Core technologies used for implementation include Grid computing and Service Oriented Architecture.GEOID provides capability to address require-ments of applications such as real-time monitoring,time series data processing and processing with user required quality to meet the requirements of end user applications.GEOID allows users to access the archive products or the raw satellite data stream and process their area of interest.Simulations show that applications such as time series analysis show considerable improvement in processing time by using GEOID.
