Geoscience Spaceborne Imaging Spectroscopy

Geoscience Spaceborne Imaging Spectroscopy (GSIS)


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.


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.


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.


The GSIS Technical Committee encourages participation from all its members. The committee organization includes the Chair and two Co-Chairs. GSIS Technical Committee Chair
