eCognition is a commercial software suite developed by Definiens AG for object-based image analysis (OBIA) of geospatial data. It transforms pixels into meaningful image objects, then classifies them using rule-based logic, contextual relationships, and machine learning. The platform supports satellite, aerial, and drone imagery, as well as multispectral and hyperspectral data and LiDAR, enabling data fusion for robust feature extraction.
Key capabilities include multi-resolution segmentation, context-aware classification, change detection, and automated workflows built from reusable rule sets. eCognition produces GIS-ready raster and vector outputs for applications such as land-cover and land-use mapping, forestry, agriculture, urban planning, and environmental monitoring. The suite has included desktop tools like eCognition Developer for building and testing rule sets, alongside server components for batch processing and large-scale production. It is aimed at remote sensing and GIS professionals who need consistent, repeatable analysis at scale and is offered under proprietary licensing, typically for Windows environments.
eCognition is developed by Definiens AG. The most popular version of this product among our users is 2.1. The names of program executable files are DIAClient.exe, DIAClientTrial.exe and eCognitionDemo.exe.
