Milestone for global geodesy

The UN calls for enhanced cooperation on global geodesy. At the UN-GGIM sixth session in New York in August, the Committee of Experts endorsed the GGRF Roadmap and decided to establish a permanent sub-committee on geodesy.

"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).
At the UN-GGIM sixth session in New York, the member states did also endorse the roadmap for the global geodetic reference frame as a principle based briefing document for national governments. The roadmap aims to enhance the GGRF and make it more sustainable.

UN-GGIM Global Geodetic Reference Frame (GGRF) Working Group has developed the Roadmap for the Global Geodetic Reference Frame for Sustainable Development. It addresses each of the key areas of action described in the operational paragraphs of the UN General Assembly resolution:

Data sharing
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.
Geodetic infrastructure
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.”
Faatasi Malologa
Director of Tuvalu Lands & Survey Department

“Geodesy most of the time being not visible to citizens, plays an imporant and crucial role in the country infrastructure.”
Dr. Luiz Paulo Fortes
Phd, Instituto Brasileiro de Geografia e Estatística

“The Global Geodetic Reference Frame provides the firm ground for all restoration works.”
Basara Miyahara
Director, Geospatial Information Authority of Japan

“We need more information about the planet in order to measure and deal with climate change.”
Jan Tore Sanner
Norway’s Minister of Local Government and Modernisation

Fundamental to sustainable development

In February 2015 the UN General Assembly adopted the resolution “A Global Geodetic Reference Frame for Sustainable Development” – the first resolution recognizing the importance of a globally-coordinated approach to geodesy.

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 extent and value to nations and the considerably increased economic benefit of implementing the Global Geodetic Reference Frame will be highlighted, alongside its role in underpinning the Sustainable Development Agenda". Dr. Vanessa Lawrence CB

The UN Committee of Experts on Global Geospatial Information Management (UN-GGIM) decided in July 2013 to formulate and facilitate a resolution for a global geodetic reference frame #ggrf. UN-GGIM recognised the growing demand for more precise positioning services, the economic importance of a global geodetic reference frame and the need to improve the global cooperation within geodesy.
UN General Assembly urges the sharing of geospatial data to benefit People and Planet
Thursday 26th of February the United Nations General Assembly adopted its first resolution recognizing the importance of a globally–coordinated approach to geodesy – the discipline focused on accurately measuring the shape, rotation and gravitational field of planet Earth.

A roadmap for the enhancement for geodesy

"Looking forward to seeing this #GGRF roadmap", says Peni Suveinakama, Fiji UN mission. New York, August 2015, from left: Peni Suveinakama, Zuheir Altamimi and Gary Johnston.
The United Nations Global Geospatial Information Management (UN-GGIM) Working Group on the Global Geodetic Reference Frame (GGRF) is now drafting a roadmap for the enhancement of the Global Geodetic Reference Frame. Importantly the roadmap will also address factors affecting the Sustainability of the GGRF.

"The Global Geodetic Reference Frame (GGRF) Roadmap will be built with passion and involvement," says Working Group co-chair Gary Johnston from Australia.

The roadmap will address five broad issues: Governance, Infrastructure, Policy - standards and conventions, Education - training and capacity building, Communication and outreach.

GGRF - fundamental for monitoring changes to the Earth

The 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.
