Quality assessment of Airborne Image Spectrometry Data for the AVIRIS-4

Abstract. The AVIRIS-4 is a state of the art imaging spectrometer developed by NASA-JPL for the consortium of Swiss universities ARES. Measurement campaigns using this instrument started in 2024. According to the agreement with NASA-JPL, all imagery produced by the AVIRIS-4 should be made available as open data. To support the efforts of the ARES consortium in improving the quality and interoperability of the produced research data, in line with the FAIR framework for open data, a new tool is proposed to label tie points on hyperspectral imagery and use them as quality control indicators of the georeferencing process. A case study on the first flight of the system acquired for the geometric calibration of AVIRIS-4 is presented. Based on the proposed quality indicators, errors in the measured trajectory data collected in flight were identified, indicating the need for a new calibration flight, further refinement of the proposed trajectory optimization framework and guiding the design of future missions.
