Land Surface Imaging

Originally, the fundamental mission of the CEOS Land Surface Imaging Virtual Constellation (LSI-VC) was to promote the efficient, effective, and comprehensive collection, distribution, and application of space-acquired image data of the global land surface, especially to meet societal needs of the global population, such as those addressed by the Group on Earth Observations (GEO) societal benefit areas (SBAs).

Discussion at the 28th CEOS Plenary (2014) confirmed the value of the LSI-VC and noted the criticality of land surface imaging data across a very wide range of societal benefit areas. The discussion also highlighted the need for strong international coordination to ensure user needs can be met while promoting the sustainability of programs. For this reason, The LSI-VC developed a new LSI-VC Implementation Plan that reflects a change in focus toward the coordination of land surface imaging space segment assets.

CEOS Analysis Ready Data for Land (CARD4L)

CEOS Analysis Ready Data for Land (CARD4L) are satellite data that have been processed to a minimum set of requirements and organized into a form that allows immediate analysis with a minimum of additional user effort and interoperability both through time and with other datasets.

LSI-VC leads the CEOS Analysis-Ready Data (ARD) initiative, including the overarching Definition, the individual Product Family Specifications, as well as the Assessment Process and outreach, advocacy, and promotion.

More information is available on the CEOS Analysis-Ready Data website.
