Strengthening the role of geodesy

"This is certainly a good day for geodesy", says Gary Johnston, one of the two co-chairs of the subcommittee.
"The new subcommittee is now established and this is an important step for improving global geodesy. We must work for the benefit of all member states," says Alexey Trifonov, who is the newly elected co-chair from the Russian Federation.
The inaugural meeting for the Subcommittee on Geodesy was convened on November 26th and 27th, and was hosted by INEGI in Mexico City in the margins of the 2017 UN-GGIM High Level Forum. 19 Member States and organisations participated in the meeting.
Australia's Gary Johnston is continuing as co-chair for the next year, while Norway's Laila Løvhøiden is stepping down.
"It is important that the co-chairing of the subcommittee is shared between the Member States as this will increase the involvement and spread the work load, Løvhøiden says. Norway has co-chaired the geodesy working group under UN-GGIM since 2013, and I am convinced that it will be very good for our work that the Russian Federation now has acceded this position".
Governance is key
The new co-chair is looking forward to start his new assignment for global geodesy.
"An appropriate governance mechanism is a keystone for future work .
The creation of the subcommittee started last year, when United Nations Committee of Experts on Global Geospatial Information Management (UN-GGIM) decided to elevate the Global Geodetic Reference Frame (GGRF) Working Group to a permanent Subcommittee on Geodesy. On the 4th August this year the UN-GGIM seventh session in New York endorsed the terms of reference and formally established the first permanent UN-GGIM Subcommittee on Geodesy.
The subcommittee will now focus on continuing the successful efforts of the GGRF Working Group.
"It is about ensuring that all countries in this world have access to precise positioning because we know it benefits their societies and the people that live within them. The geodetic reference frame makes this possible." says Gary Johnston.
The work on developing an implementation plan for the GGRF Roadmap and a position paper for a governance structure is progressing and will be reported to the UN-GGIM Committee of Experts at its eighth session in August 2018.
"We are about strengthening the role of geodesy in society and providing a greater governmental mandate that will hopefully result in sustainable operations of geodetic infrastructure and capacity development programs as well", says Johnston.
To support science and society

Following UN-GGIM sixth session, the GGRF Working Group made a plan for the transition to become the subcommittee on geodesy and drafted the Terms of Reference (TOR) for the subcommittee. The draft TOR will be tabled for endorsement at UN-GGIM seventh session.
The arrangement of the inaugural formal workshop of the subcommittee is tentatively planned in the margins of the 2017 UN-GGIM High Level Forum in Mexico City.
The work with the Roadmap implementation plan and the position paper to define the appropriate governance arrangements for the GGRF is progressing.
The ambition is that the implementation plan will be the first step on the road towards an accurate, accessible and sustainable Global Geodetic Reference Frame to support science and society, which also is the vision of the implementation plan.
As encouraged by the UN-GGIM Committee of Experts, the interim subcommittee has during the last year continued its efforts in making the GGRF more visible and understandable to stakeholders and society.
The dedicated communication and outreach work has resulted in increased engagement and awareness of the importance of the global geodetic reference frame. As an example, a Norwegian film company has produced the international documentary film on geodesy “Quest for the Exact Position”.
A world preview of the film will be shared with the participants of the GGRF Side Event during UN-GGIM seventh session in New York.

"This is a significant milestone for global geodesy. It sends a very clear message to member states, and other global geodetic entities, that the focus on enhancement of geodetic reference frames should be a long term strategic priority for governments," says Gary Johnston, co-chair of the UN-GGIM Working Group on the Global Geodetic Reference Frame (GGRF).

Development of geodetic standards and open geodetic data sharing are required to enhance and develop the GGRF.
Education and capacity building
Appropriate geodetic skills and educational programs are essential for the development, sustainability and utilization of the GGRF.
A more homogeneous distribution of geodetic infrastructure is needed to develop and utilize an accurate GGRF.
Communication and outreach
It is imperative to develop communication and outreach programmes that enable the GGRF to be more visible and understandable to society.
The development and sustainability of the GGRF is reliant on an improved governance structure.
Significant benefits to the study of our changing planet
“Accurate geospatial infor- mation provides a critical foundation for sustainable economic development.”
“Geodesy most of the time being not visible to citizens, plays an imporant and crucial role in the country infrastructure.”
“The Global Geodetic Reference Frame provides the firm ground for all restoration works.”
“We need more information about the planet in order to measure and deal with climate change.”
Fundamental to sustainable development

Geodesy plays an increasing role in people’s lives, from finding directions using a smart phone to alleviating poverty.
Because the Earth is in constant motion, an acccurate point of reference is needed for making measurements. Geodesy provides a very accurate and stable coordinate reference frame for the whole planet: A Global Geodetic Reference Frame.

"The Global Geodetic Reference Frame (GGRF) Roadmap will be built with passion and involvement," says Working Group co-chair Gary Johnston from Australia.
GGRF - fundamental for monitoring changes to the EarthThe Global Geodetic Reference Frame is fundamental for monitoring changes to the Earth including the continents, ice caps, oceans and the atmosphere. It is also fundamental for mapping, navigation and universal timing.
The ability to position both information and objects accurately will be an increasingly important driver of productivity into the next decade.
The Global Geodetic Reference Frame is a key enabler for monitoring disasters - and recovering from them.
Identifying areas under threat of flooding, earthquakes and droughts – and taking measures to counteract these.
Monitoring sea level changes, plate movements, land uplift and ice sheet and glacier changes – so that global society can follow changes to the Earth system and plan accordingly on a local, regional and global level.
