| Abstract: | During the past years, crop yield estimation has gained increasing concerns within scientific literature of china. The paper inquired into the characteristic, system architecture of spatial data warehouse and valued crop yield estimation methods we have now. Since many factors influence agricultural estimating, a trial is suggested to apply spatial data warehouse technology in the research of crop yield estimation and modal of multi-dimensions were built. Thus agricultural decision-making department can obtain reference. |
