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.
