Compact Hyperspectral Prism Spectrometer: Recent Flight Campaign and Applications to the Future of Sustainable Land Imaging
Abstract
The 2013 NRC report Landsat and Beyond: Sustaining and Enhancing the Nations Land Imaging Program recommended that the nation should "maintain a sustained, space-based, land-imaging program, while ensuring the continuity of 42-years of multispectral information." With the Compact Hyperspectral Prism Spectrometer (CHPS) being developed under funding from the Sustainable Land Imaging (SLI) Technology program at NASA ESTO, Ball Aerospace intends to meet the need for multispectral continuity and enable new global spectroscopic studies. A compact spectrometer that maintains Landsat's legacy of accurate and stable calibration is key to sustainably meeting the needs of the Landsat community and in developing new hyperspectral approaches for surface ecology and biodiversity studies, water quality monitoring, and land use studies.
To demonstrate that the CHPS technology can perform Landsat science and enable new hyperspectral studies, results of a recent airborne imaging campaign will be presented. Use of Ball's Operational Land Imager (OLI) and OLI-2 calibration facilities and methodologies along with an in-flight calibration system that tracks changes in the airborne instrument will aid evaluation of the CHPS design in preparation for spaceflight development. Measurements from cross-calibration ground targets, in-flight stability, and Landsat under-flights will be presented. The presentation will highlight the targets of interest collected, data format and availability to encourage additional collaboration for new data products with this high resolution visible to short wavelength infrared imaging spectrometer dataset. A new era of global spectroscopic measurements will rely on stable and well-calibrated visible to short wavelength infrared spectrometers. CHPS demonstrates this capability in a recent airborne imaging campaign with a compact instrument using a spaceflight compatible design. An additional airborne campaign is planned for 2019 offering new opportunities to address surface biology and geology science.- Publication:
