Last August the 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.
decision the GGRF Working Group drafted the Terms of Reference (TOR) for the
subcommittee and developed a transition plan from Working Group to Subcommittee
on Geodesy. This August, during the UN-GGIM seventh session, the Terms of
Reference and transition plan were endorsed by the UN-GGIM Committee of
Experts. The transition phase will end at the inaugural meeting of the
subcommittee where co-chairs will be elected in line with the TOR’s . Until
then the subcommittee will continue to be co-chaired by
Australia (represented by Geoscience Australia) and Norway (represented by the
Norwegian Mapping Authority).
Long term priority
"The creation of this subcommittee in
the United Nations System, the first for UN-GGIM, sends a very clear message to
Member States, and other global geodetic entities, that
enhancement of geodetic reference frames should be a long term strategic
priority for governments,” says Gary Johnston, co-chair of the UN-GGIM
Subcommittee on Geodesy.
IAG supports UN
The IAG has been a member of the GGRF
Working Group from the start and will be an associate member of the new
Subcommittee on Geodesy.
International Association of Geodesy supports the transition to the new
Subcommittee on Geodesy. We also applaud the continued progress in developing
an implementation plan for the GGRF road map. The International Association of
Geodesy, through its geodetic services as well as the Global Geodetic Observing
System, will continue its long-standing support of developing a global geodetic
reference frame for the benefit of science and society,” says Dr. Michael
Pearlman, who represented the IAG in New York.
Alligned with NASA
"The activities of the UN-GGIM,
specifically its Subcommittee on Geodesy and the implementation of the
recommendations described in the road map on the Global Geodetic Reference
Frame, are well aligned with NASA geodesy goals," says Dr. Benjamin
Phillips, program scientist for NASA's Space Geodesy
Program in Washington and also present at the UN-GGIM seventh session in New
Subcommittee on Geodesy will help to facilitate the international collaboration
that is critical to realizing the objectives of the global geodesy community,
and further the associated scientific and societal benefits," says

Along with the
planning of the inaugural meeting the subcommittee is working on the
development of the implementation plan for the GGRF roadmap.
is progressing and the intention is to present the plan to the UN-GGIM
Committee of Experts at its eight session in August next year”, says Laila
Løvhøiden, co-chair of the UN-GGIM Subcommittee on Geodesy.
“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,"
The framework for an appropriate governance
mechanism is beginning to take shape. The focus group assigned to develop the
position paper agrees that in order to effectively implement the road map for
the global geodetic reference frame, some kind of intergovernmental arrangement
must be established. “Recognizing the critical importance of such a governance
structure, it´s imperative that we engage in broad consultations before we
conclude,” says Laila Løvhøiden, team lead of the UN-GGIM GGRF
governance focus group.

Association of Geodesy (IAG) and the International Association of Seismology
and Physics of the Earth’s Interior (IASPEI) held for the first time a joint
Scientific Assembly from July 30 to August 4, 2017 in Kobe, Japan. Overall 43
symposia were organized, 7 IAG, 27 IASPEI and 9 Joint Symposia. By the
deadline, authors from 74 countries had submitted 1270 abstracts, 290 for IAG,
650 for IASPEI and 330 for the Joint Symposia. Altogether 1107 attendees from
65 countries registered, 361 of those with preference for IAG.
In total, 15 IAG travel awards were granted to young
scientists for participation and presentation in the assembly. During the IAG
Opening Session, IAG young author awards were presented to Xingxing Li, GFZ Potsdam, Germany, and Olga
Didova, DUT, The Netherlands, for best publications in the Journal of Geodesy
in the years 2015 and 2016, respectively (see IAG Newsletter July 2017).
The IAG Symposia were divided according to the IAG
structure of Commissions, Services and the Global Geodetic Observing System
(GGOS); the Inter-Commission Committee on Theory being involved in all
G01 Reference frames (50 presentations);
G02 Static gravity field (63 presentations);
G03 Time variable gravity field (38 presentations);
G04 Earth rotation and geodynamics (31 presentations);
G05 Multi-signal positioning: Theory and applications (26
G06 Geodetic remote sensing (39 presentations);
G07 GGOS and Earth monitoring services (43 presentations).
Main topics of the G01
symposium were the International Terrestrial Reference Frame (ITRF), the
Celestial Reference Frame and VLBI, regional reference frames and networks, the
methodology and implementation of reference frames, and the combination and co-location
of space geodetic techniques.
The G02 symposium dealt with the theory and methods of
gravity field modelling, gravimetry, regional gravity and geoid determination,
applications of the gravity field, satellite altimetry and the marine geoid,
and height systems.
Presentations in G03 concentrated on time-varying gravity
field estimation, methods and solutions. Current and future satellite gravity
missions, mass transport and redistribution, and applications to Solid Earth,
atmosphere, cryosphere, and hydrosphere studies were discussed.
The themes of G04 included specific topics of Earth
rotation (nutation, EOP, polar motion, angular momentum, excitation functions,
etc.) and geodynamics (horizontal and vertical crustal movement and
deformation, tectonic elements, and strain measurements).
Principal topics of G05 were indoor and outdoor navigation,
single and multi GNSS analyses, and positioning applications.
The G06 symposium addressed in particular the monitoring of
the atmosphere (troposphere and ionosphere) and space weather. Methods
concentrated mainly on GNSS sensing, VLBI, and GNSS reflectometry.
Themes of the symposium G07 were split into activities on
reference frames and gravity, especially those of the GGOS Bureaus, the
observation networks and co-locations, and the GGOS focus areas on height
systems, geohazards, sea level, and space weather research.
Due to the seismic
region of the venue, the joint symposia included particularly themes related to
earthquakes and generated deformations:
J01 Monitoring of the cryosphere;
J02 Recent large and destructive earthquakes;
J03 Deformation of the lithosphere: Integrating geodesy and
seismology through modelling;
J04 Geohazard early warning systems;
dynamics: Multidisciplinary approach to seismogenesis;
spectrum of fault-zone deformation processes (from slow slip to earthquake);
J07 Tracking the sea floor in motion;
J08 Imaging and interpreting lithospheric structures using
seismic and geodetic approaches;
J09 Geodesy and
seismology general contributions.
In the following, we
shall mention specific topics related to IAG activities.
The symposium J01 included contributions to the glacial
isostatic adjustment in Antarctica, Scandinavia and North America, glacier
velocities, and sea level rise due to melting, using data from absolute gravity
measurements and dedicated satellite missions.
In symposium J02, there were studies of co-seismic crustal
deformation caused by large earthquakes in different regions of the Earth,
while the symposium J03 dealt with results of
post-seismic deformation using GNSS campaign or continuous observations.
Time-series analyses and regional deformation patterns were presented using
The geodetic contributions in J04 concentrated on real-time
observations by GNSS precise point positioning and ionosphere disturbances as
well as real-time sea level observations by satellite altimetry.
The symposium J05 included presentations of crustal
deformations derived from GNSS and InSAR observations in various seismically
active regions of the Earth.
In symposium J06, there were contributions on fault-zone
deformations derived from gravity changes and strain-measurements.
Geodetic contributions in symposium J07 concentrated on
detecting sea floor deformations by combining GNSS and acoustic observations.
In addition, GRACE observations were used for modelling the ocean bottom
The symposium J08 included studies on the inversion of
gravity anomalies and gravity field models for interpreting the lithosphere
The symposium J09 was open to any topic not covered by the
other joint symposia. Geodetic contributions dealt with InSAR observations for
analysing earthquake types, tide gauge records for tsunami studies, and GNSS
observations for specific crustal motions.
There were many
innovative and trend-setting contributions in all the symposia. A very positive
fact was that the session chairs observed strictly the time for presentations,
so there was nearly always time for questions and discussion, and no truncation
of talk time. Reviewed papers will be published in the IAG Symposia Series at
Springer-Verlag. The deadline for submission is September 30, 2017.
