CEOS ARD Oversight Group

​

​

• SIT-TW-2021-02: Nominations were requested to ensure robust support for a CEOS ARD Oversight Group
• Identified as a core component of the future CEOS ARD Governance Framework.
• Act as a forum for all matters related to CEOS ARD.
• Representatives from the CEOS Virtual Constellations are integral to the effort going forward, as these are the CEOS entities with the technical expertise to recommend, develop and maintain Product Family Specifications.
• The SIT Chair Team and CEOS Executive Officer have also been identified as key participants.
• Also provide:
• Strong coordination across CEOS
• Promote CEOS ARD in a unified way

Nominations to the CEOS ARD Oversight Group are welcomed today as well as at any point following the meeting

CEOS Plenary, 1-4 November 2021

Framework/Template PFS: Some Key Points...

​

​

• CEOS Virtual Constellations (VC) will serve as the forums in which new PFS are proposed and developed, and in which products are assessed.
• PFS will be developed when producers, experts and users perceive that there is a benefit and are prepared to invest in the effort to develop PFS, manage the process, and undertake to produce the data.
• A template “bare bones” PFS has been developed to provide a starting point for future PFS, to ensure commonality in layout, general structure, interpretation and approach.
• Provides a foundation and common suite of assessment factors for all PFS (optical, Radar etc.) and well as stipulations for additional required factors. Composed of ~20 assessment factors.
• About ½ to ⅓ the size of a typical full existing PFS
• Most of the proposed terms in the General Metadata category
• Per Pixel and Corrections sections have specific guidance and recommendations for for organization for PFS authors to follow.
• Highly adaptable to other disciplines areas.
• No limitations on additional assessment factors
• (Nearly) backwards compatible with existing PFSs

Strategy 2021

Slide 11

CEOS Plenary, 1-4 November 2021

Context

​

​

• The CEOS ARD Strategy was developed in 2019/20 and was designed around the CSIRO/GA term as SIT Chair
• Addressed the transition from CARD4L through to CEOS ARD in general
• Was linked to the SIT Chair priorities, action-oriented
• Covered four main areas: User Needs & Specifications; Assured Production & Access; Pilots & Feedback; Communication & Promotion
• The revised Strategy needs to support the ongoing ‘business as usual’ of CEOS ARD
• Maintain the current specifications
• Support new CARD-compliant datasets, land and non-land
• Engagement and outreach
• & etc.
• Process:
• Draft circulated
• Presentation at SIT WS
• Additional input - Revised and final draft
• Plenary for endorsement

Slide 12

CEOS Plenary, 1-4 November 2021

CEOS ARD Strategy 2021: Some Key Points...

• CEOS ARD Strategy 2021 provides direction for the next stage of CEOS activity on ARD.
• The focus for the Strategy is to ensure that CEOS data is as impactful as possible, and that such impact is sustained, including via an increased scope of the CEOS ARD concept beyond the land domain.
• Leadership, Governance and Accessibility and utilisation of CEOS ARD emerge as pillars of the strategy
• Emerging, new objectives to be supported by the 2021 Strategy:
• Continued oversight and maintenance of CEOS ARD ensuring that CEOS’ ARD work continues to be coordinated and guided by an appropriate governance framework.
• Ensure the suitability of CEOS ARD for the machine-to-machine processes employed for the application of remote sensing data.
• Continued evolution of the concept of CEOS ARD, to consider products that are further along the production chain (‘ARD+’).
• Continue investigating further opportunities for the CEOS ARD concept to streamline user uptake of satellite Earth observation data, including new thematic domains and applications.

The CEOS ARD Strategy 2021 is presented for endorsement.
