      GEOWAY CIPS

      GEOWAY CIPS (Clustered Image Processing System), an innovation supported by  the National Development and Reform Commission’s High-Tech Industrialization of Satellite Applications Project (Project No. 37 [2010]), is a complete technical solution for fast and batch processing of large-scale remote sensing images in a network computing environment. The core part of CIPS is automatic processing of massive remote sensing imagery based on high-performance cluster computing environment.
