The Land Surface Imaging Virtual Constellation (LSI-VC) exists to maximize the value derived from CEOS Agency land surface imaging assets and activities by providing an overarching coordination role.
The responsibility of the LSI-VC is to facilitate coordinated and optimized land surface imaging contributions from CEOS Agencies to enable access to fundamental measurement products in support of confirmed/validated requirements linked to adopted CEOS priorities. These priorities are typically derived from scientific users and key stakeholders, such as UN agencies/programs and GEO.
Specifically, the LSI-VC applies a CEOS multi-agency perspective to the following activities:
- Assessing land surface imaging data requirements, identifying the fundamental measurements that are required from land surface imaging assets to meet them, and undertaking gap analyses.
- Facilitating the coordination of mission development to ensure the overall set of space assets is optimized, within the supplying organizations’ abilities and constraints, to support the overall package of validated data requirements.
- Harmonizing, based on inputs received, periodic acquisition planning to optimize asset use; helping to resolve competing requirements; and promoting resilience and redundancy of the Virtual Constellation.
- Support the coordination of the retrieval and reprocessing of historical products to fill gaps in archives where required to support validated time series analysis requirements.
- Support the coordination of the implementation of consistent calibration and pre-processing approaches so that observation data are used to produce comparable fundamental measurement products for user benefit.
- Support the implementation of CEOS land surface imaging data processing, distribution and analysis capabilities (such as those being developed by the CEOS Systems Engineering Office (SEO) and the Working Group on Information Systems and Services (WGISS)), which enable the broadest user access to fundamental measurements for generating derived products.

The 2019 CEOS Plenary endorsed the transition of the Ad Hoc Space Data Coordination Group for GFOI to become a thematic subgroup on Forests & Biomass within LSI-VC, and likewise endorsed the transition of the Ad Hoc CEOS Working Group on GEOGLAM to become a thematic subgroup on GEOGLAM. These subgroups are dedicated to a specific thematic area and will maintain their relationships with their respective stakeholders and user communities. They will focus on data acquisition and requirement strategies for their thematic areas, which will feed into the overall requirements worked by LSI-VC.
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 CARD4L initiative, including the overarching Definition, the individual Product Family Specifications, as well as the Assessment Process and outreach, advocacy, and promotion.
