The meeting was convened in accordance with Statistical Commission decision 44/101 and UN-GGIM decision 3/107, which welcomed the proposal to establish an Expert Group on the Integration of Statistical and Geospatial Information supported by the Eurographics.
to bring together experts from both statistical and geospatial information communities to work for the development a global geospatial-statistical framework and address issues related to the integration of statistical and geospatial information.
The objective of the fourth EG-ISGI is to create an opportunity to review and consider the recent (2016 and 2017) decisions of UN-GGIM and the UN Statistical Commission relating to the Global Statistical Geospatial Framework (GSGF), the 2020 round of Population Censuses, and the activities of the Expert Group going forward.
On November 6th :
UNECE and Statistics Sweden presented on - GAMSO, GSBPM V5, GSIM, CSPA
The Co-chair of the expert group meeting of ISGI (Martin Brady - ABS) emphasised the below Integration model :
The international community has recognised the challenge of better integration of geospatial and statistical information and has endorsed the United Nations - Experts Group on the Integration of Statistical and Geospatial Information (EG-ISGI) to develop a Global Statistical Geospatial Framework (GSGF), which was approved at the sixth annual meeting of the United Nations - Committee of Experts on the Global Geospatial Information Management (GGIM) and endorsed by the 48th United Nations Statistical Commission in March 2017.
OGC, ISO/TC211 are the main standards related organizations to participate in this meeting.
Methods like Discrete Global Grid Systems, StadCAT, GeoDCAT (Eurostat and JRC) were presented in detail. It was followed by a Panel discussion on - Future works : Collaboration accross communities.
On November 7 :
INSPIRE and SDMX : Eurostat carried out a successful pilot study to integrate INSPIRE concepts into SDMX in the context of the Census 2021 data collection. A mapping between the INSPIRE themes Population distribution and Statistical Units on the one hand and Census data and metadata modelled in SDMX for the exchange of census information on the other was defined and will be implemented in Eurostat's SDMX enabled data exchange infrastructure, the Census Hub.
ISTAT emphasised on the WebGIS and Poland dwelled on their 10 Level Model for GSGF.

Challenges and Solutions :
Switzerland proposed geocoded registration data as the core for production of geo-statistical data-

Statistics Canada’s expertise in gathering and providing vast store of data that matters intuitively couples with NRCan’s expertise in geospatial data technologies and applications. Undertaking this work will build on years of collaboration in other areas.Under the Open Government Implementation Plan (OGIP), which ensures that the Government of Canada implements digital data transparency (Government of Canada, 2015), the Treasury Board of Canada Secretariat engaged Statistics Canada to build and maintain a new version of Canada’s Open Data Portal.

On November 8 :
Innovation has been the key emphasis of this day's discussion and well supplemented by the views of US Census bureau.
OGC emphasised the existing standards, 52North GMBH presented its view on Open tools
Portugal presented its existing Grid cell approach
Final discussion : ISO TC 307 must take good role in the entire update of the datasets.
Author's opinion : In the seventh session of UN ECOSOC. The agenda point 25 emphasise about the cooperation between two TC before 8th session. FIG is a Liaison to both the committees and hence has informed interest in this collaboration - "25. The use of Blockchain technology with geospatial information continues to strengthen, therefore ISO/TC 211 has established a liaison with ISO/TC 307 Blockchain and Electronic Distributed Ledger Technologies". So perhaps it could be considered during integration too. DLT is being used in Land and property, climate ledger. This will sure has an impact on statistical datasets like valuations, taxation etc. The census 2021 if missed for this pilot technology then it would be heard only in 2031. This exercise will impact datasets related to valuation and taxation and hence has it linked to Fin-tech. An Open statistical consortium (#OSC) is a way forward and perhaps at TLF we are able to contribute towards such a proposal.
