Vegetation Index Focus Area: Strategic Plan 2021-2023
This strategic plan outlines activities, validation methods, and development milestones for the Vegetation Index Focus Area from 2021 to 2023. Initiatives include updating product lists, drafting validation protocols, and engaging with the VI community for feedback and collaboration. The plan culminates in the final approval of the VI validation protocol in June 2022. Key activities such as MODIS and VIIRS validation, as well as ENDVI validation, are detailed in the plan, highlighting a comprehensive approach to enhancing vegetation index research and applications.
