Data in Use
The ImageQuerying system can process any airborne/spaceborne EO multi-spectral image with a radiometric calibration metadata file (such as Sentinel-2/-3, Landsat, MeteoSat, RapidEye, WorldView, etc).
ImageQuerying (IQ) is a near-real-time image comprehension and querying system for big Earth data. Based on low-level computer vision, IQ provides each image stored in a database with at least one thematic map generated through a fully automated process. Image objects can be tracked by the IQ inference engine over time in a manner similar to symbolic human thinking. Users can also generate information layers by querying and combining the maps stored in the database.
Cross-domain academic, public, or commercial users of Earth observation imagery – as well as data providers – will benefit from ImageQuerying as a real-time visual tool for mining EO big data with autonomous image-interpretation intelligence complementary to that of the operator.
«ImageQuerying is an innovative application that simplifies and accelerates the analysis of big EO image data. The images and image time-series are automatically pre-classified and stored in a raster database, thus allowing users to perform geospatial semantic queries on large EO archives via an easy-to-use interface. The application quickly transforms image data into information, creating real value for the customer.»
