研究目的
To provide an overview of the DESIS instrument, its on-ground data processing, in-flight calibration, and product quality investigations.
研究成果
From 2018 onward, the DESIS sensor on board the ISS will provide hyperspectral data for commercial and scientific applications. DLR is developing a processing chain to generate well-calibrated data products up to orthorectified and atmospheric corrected data that include metadata and quality control information.
研究不足
The study is limited by the operational constraints of the ISS, the specific design parameters of the DESIS instrument, and the need for regular validation and quality control to ensure data quality.
1：Experimental Design and Method Selection:
The study involves the development and operation of the DESIS hyperspectral sensor, including its processing software, in-flight calibration, and product quality operations.
2：Sample Selection and Data Sources:
Data from the DESIS instrument on the ISS, including hyperspectral imaging data.
3：List of Experimental Equipment and Materials:
DESIS instrument, MUSES platform, processing software.
4：Experimental Procedures and Operational Workflow:
Launch and installation of MUSES on the ISS, followed by DESIS; data processing, calibration, and quality control.
5：Data Analysis Methods:
Use of processing chains for systematic and radiometric correction, geometric correction, and atmospheric correction of DESIS data.
