\nin-person meeting on 5th October 2022 in Tokyo JAPAN.\u00a0 Seventy-seven members from
\n21 organizations joined the meeting. The agenda, presentations and
\nminutes can be found in the WGISS-54 web site.<\/a><\/p>\n![\"\"](\"https:\/\/ceosnews.xsrv.jp\/ceos-newsletter\/wp-content\/uploads\/2022\/12\/2022.12_WGCV-WGISS-joint-meeting2-300x129.jpg\")
<\/p>\n
\nexchange information, identify common interests and foster joint
\ncollaborations.\u00a0 The main topics in this meeting were as follows.<\/p>\n
\nSynergies, and Improvements
\nThe status of CEOS CAL\/VAL Portal, ESA EO Portal, CEOS Missions,
\nInstruments, and Measurements (MIM) Database, which are being modernized
\nwas reported to get improvement ideas and consider connectivity with
\nother CEOS systems. A link between the MIM and the ECV inventory, and
\nautomation for the data providers to enter their information were suggested.<\/p>\n
\nLSI-VC (Land Surface Imaging Virtual Constellation) introduced CEOS
\nAnalysis Ready Data (ARD) activities to foster engagement of WGCV and
\nWGISS. The CEOS motivation to engage in ARD activities is to facilitate
\ndata usage by reducing data processing burden on users, looking toward a
\nfuture of sensor-agnostic Earth data where the uptake and impact of all
\ndata sources for societal benefit are maximized. CEOS-ARD is a key step
\nwithin the \u2018interoperability spectrum.\u2019
\nOverwhelming feedback from industry is that formal standards are needed
\nfor ARD which will facilitate the implementation of CEOS-ARD into
\noperational workflows and to ensure products interoperability.<\/p>\n
\nWGCV gave a presentation on data quality indicators, which can be expressed in
\ndifferent layers of information (per pixel, per measurement, as cal\/val
\nresults summary, as summary quality in the metadata, and in tools and
\nprocedures).
\nFormat is an important aspect of EO data products that ensures they are most
\neasily accessible to the widest variety of users.
\nProduct metadata and flags offer users important extra layers of useful
\ndescriptive information in addition to the measurements themselves that
\ncan be crucial to their analysis.
\nA cal\/val maturity matrix provides a reader with the high-level summary
\nof the output of a quality assessment. The matrix contains a column for
\neach section of analysis and cells for each sub-section of analysis.
\nSub-section grades are indicated by the color of the respective grid
\ncell, which are defined in the key.<\/p>\n
\nBackground and Definitions
\nWGISS gave a presentation on the Data Management and Stewardship Maturity Matrix
\n(DMSMM). The DMSMM defines all activities needed to preserve and
\nimprove the information content, quality, accessibility, and usability
\nof data and metadata. It provides a way to measure the status of the
\nagency data stewardship processes in place, and to plan goals for future \u00a0data
\nstewardship processes and projects.<\/p>\n
\nThe AVHRR DMSMM Use Case was reported. The evaluation is being performed
\non the AVHRR L1B Dataset using the Cal\/Val Maturity Matrix (a subset of
\nthe DMSMM) and is currently in progress.<\/p>\n
\nA presentation on the CEOS Interoperability Framework Initiative was
\ngiven by LSI-VC. This framework should help coordinate and
\nstreamline CEOS efforts, and support LSI-VC and SIT decisions.
\nAddressing the full scope of interoperability requires a framework that
\ncaptures all aspects of the problem. The following (non-exhaustive list)
\nare equally important factors to consider, and each have several
\ncomponent pieces:
\n– Structural \/ Data Architecture
\n– Accessibility \/ System \/ Data Presentation
\n– Formats \/ Syntactic \/ Data Language
\n– Terminology \/ Semantics \/ Data Context<\/p>\n
\nLSI-VC, WGISS, WGCV, etc.), and therefore a robust framework and
\ncoordination mechanisms are needed to address all the necessary pieces.<\/p>\n
\nWGISS and WGCV
\nThe CEOS Common Online Dictionary team reported its progress as a result of
\na joint collaboration between WGCV and WGISS.\u00a0 The team has completed
\nthe merge of WGCV and WGISS glossaries and NOAA NESDIS Lexicon on a
\ntechnical level into a temporary Wiki solution<\/a>.<\/p>\n
