The INTA AHS system has been operational since 2004, having performed over 60 flight campaigns throughout Europe up to the present time. The system is formed by an airborne scanner (AHS), a navigation system, calibration equipment, and a specific processing chain that have been implemented within the INTA airborne data Processing and Archiving Facility (PAF). In this chain, raw data (level 0 product) is transformed to at-sensor radiance (level 1b) and later to georeferenced at-sensor radiance (level 1c). Other processing levels, as atmospherically corrected reflectance, temperature or emissivity (L2b / L2c), can also be produced. The resulting image products are delivered together with radiometric statistics, metadata and quality descriptors according to EUFAR HyQuaPro recommendations. In this paper, details about this processing chain are given. The paper also describes the procedure for in-flight geometric calibration (internal orientation calibration and boresight estimation). Finally, an evaluation of the product accuracy (radiometric, spectral and geometric) is presented, using imagery from different AHS campaigns.
