摘要: Advances in the image retrieval (IR) field have contributed to elaboration of tools for interactive exploration and extraction images from huge archives associating content with semantic meaning. This paper presents an Earth-observation (EO) IR system based on enriched metadata, annotations, called EO retrieval. generates EO-data model by using automatic feature extraction, processing product defining semantics, which later is fully exploited supporting complex queries. In order demonstrate functionality system, we created a catalog TerraSAR-X as application scenario. The database composed 39 high-resolution scenes comprising about 50 000 patches (160 × 160 pixels) their descriptors, 100 metadata entries each scene, 330 annotations. Many query examples combining full exploitation are presented.
