LSI-VC-7

Event Dates: February 14th - 15th, 2019

7th Meeting of the CEOS Land Surface Imaging Virtual Constellation (LSI-VC)

14 – 15 February 2019

Hosted by VAST-VNSC

Hanoi, Vietnam

Meeting Minutes & Actions: DOC

The seventh meeting of the LSI-VC marks a milestone for the CEOS Analysis Ready Data for Land (CARD4L) work in particular. This meeting will see the final pieces of the framework completed, allowing CARD4L assessments to begin. The CARD4L Product Family Specification (PFS) portfolio is also expected to be updated and expand to cover more specific Synthetic Aperture Radar (SAR) products. In addition, further LSI-VC work threads will be discussed (e.g., Moderate Resolution Interoperability, MRI; global data flows) and possibly revived (e.g., requirements and gap analyses).

Objectives

The formal objectives of LSI-VC-7 are as follows:

CARD4L Product Family Specifications (PFS)

  • Review the overall status and outlook for the PFS.
  • Endorse any proposed updates to the existing PFS (Surface Reflectance, Land Surface Temperature, SAR Backscatter).
  • Present the latest on the new Synthetic Aperture Radar PFS for discussion.
  • Review the latest on the broader CEOS ARD strategy being championed by the SIT Vice Chair and confer on the inputs from our side ahead of SIT-34 (ref: CEOS-32-06).

 CARD4L Product Assessments

  • Confirm POCs for the self-assessment peer review process with WGCV.
  • Confirm a self-assessment template/approach and initiate trial runs with WGCV (following up and closing action LSI-VC-6-08).
  • Define a target portfolio of CARD4L datasets and discuss actions and milestones necessary to have this in place by the end of 2019. This should include a discussion about what we need to do to encourage dataset producers to do the self-assessments.
  • Continue the discussions around: engaging external groups in the self-assessments; CARD4L and standards, requirements versus guidelines, compliance/stamp of approval, etc. 

CEOS ARD Pilots & Promotion 

  • Review our efforts around CEOS ARD promotion and revisit our strategy for achieving broad awareness and uptake of the CARD4L concept – including our engagement with groups working on parallel ARD efforts.
  • Review the CARD4L pilot activities, including those of the 2019 VAST-VNSC CEOS Chair Initiative, SDCG, GEOGLAM, and Open Data Cube. Review lessons learned, feedback on the PFS, and actions to be taken to advance CARD4L pilot activities.

Global Data Flows 

  • Drawing on the experience of the CARD4L pilots and other ‘big data’ efforts, assess the current state of global data flows for large satellite EO datasets.
  • Discuss the trends around putting data and analytics together in the cloud. 

Requirements and Gap Analyses 

  • Continue the discussions around rebooting the requirements and gap analysis work thread of LSI-VC.
  • Demonstrate the MIM Database API and other CEOS information systems’ tools for gap analysis, and discuss further needs and work.
  • Discuss possible LSI-VC applications of CEOS information system tools (e.g., for annual reports; web portal; LSI toolkit supporting gap analyses, ref: JM-05; etc.).
  • Discuss what communities would need to be consulted in the development of any pre-compiled/automated analyses, tools, and reports. 

Moderate Resolution Interoperability (MRI)

  • Continue the discussion around defining the interoperability spectrum.
  • Review the existing MRI activities currently underway (e.g., USGS-ESA Landsat/Sentinel-2) and determine any additional MRI-related activities to be pursued (e.g., GEOGLAM and/or SDCG for GFOI case studies, GEO-LEO case study).
  • Decide whether there are any CEOS-level tasks needed on this topic. This should include consideration of the resources available for MRI, potential participation, targets, and the identification of a lead for any future MRI-related CEOS Work Plan Tasks/Deliverables.

Other Matters

  • Present agency updates focused on ARD-related matters.
  • Review and discuss LSI-VC’s draft response to CEOS-32-13 – a plan forward for the proposed merger of SDCG for GFOI and the CEOS Ad Hoc Working Group on GEOGLAM into LSI-VC – which is due for presentation at SIT-34 in April 2019. This could include revised terms of reference.
  • Review LSI-VC team status and participating agencies.
  • Prepare for LSI-VC-8.
