This document summarizes an eCognition image analysis system. It discusses the eCognition processing chain which takes in input data and performs segmentation, classification, and context analysis to output results as raster, vector, point cloud, or statistics. It describes the eCognition software suite including Developer, Architect, and Server products. It outlines a scalable processing system with centralized data storage, processing units, and thin clients to connect field offices via terminal servers. Finally, it discusses eCognition technology layers from custom to off-the-shelf applications and the underlying eCognition software suite.

- 6. Conclusion ! Scalable processing system (easy extension) ! Fast processing and high data throughput due to optimized hardware environment in headquarters – Data storage – Processing units – High speed network ! Connection to field offices with low band width via terminal server technology – Low band width – Basic hardware requirements – Reduced maintenance ! Open system for diverse applications based on eCognition technology – Habitat mapping – Cadastral update (change detection) – Suitability analysis for solar energy production (roof cadastre) – Etc.
