Geoscience Spaceborne Imaging Spectroscopy (GSIS)
WELCOME
The Geoscience Spaceborne Imaging Spectroscopy Technical Committee (GSIS TC) provides a community of practice for all stakeholders engaged in spaceborne imaging spectroscopy with an emphasis on geoscientific applications.
Topics
Relevant topics of discussions includes calibration and validation, interoperability among missions, ‘best practice’ mission implementation, mass data management challenges, the development of a forward work plan for improved coordination activities amongst national space agencies, information extraction and, standardization of data products.
Mission
The mission of the GSIS TC is to share information on future spaceborne imaging spectroscopy (“hyperspectral”) missions, to provide opportunities for new partnerships between national space agencies, commercial spaceborne imaging spectroscopy data providers, research institutions and user community, and, to build a knowledge base on underpinning capabilities required for imaging spectroscopy missions to enable uptake of spaceborne imaging spectroscopy by the geoscientific community.
Organization
The GSIS Technical Committee encourages participation from all its members. The committee organization includes the Chair and two Co-Chairs.

Working Group on Spectroscopic Sensing of Earth Materials Geoscience Spaceborne Imaging Spectroscopy Technical Committee (GSIS TC)
Mission Statement: “Expanding our spectroscopic understanding of rocks, sediments, and soils.”
We are improving algorithms that characterize geology and geochemistry, that detail associated physical and chemical processes, and that link geology to biological function. We are developing applications that promote the health of communities and the environment. We are expanding the number of well-validated case study areas to evaluate and compare existing and new sensors and algorithms.
