A series of Hotine-Marussi symposia on
Mathematical Geodesy represents a main venue for theoretically oriented
geodesists. The tradition of these symposia started in 1959 with the first
Symposium on Mathematical Geodesy organized by Antonio Marussi in Venice,
Italy. The first symposia were strongly influenced by Martine Hotine. After his
death in 1968, they were called after him. After Marussis death in 1984, the
series was finally renamed to the Hotine-Marussi symposia. Since 2006 the
Inter-Commission Committee on Theory (ICCT) of IAG is responsible for their
Hotine-Marussi Symposium on Mathematical Geodesy was held from 18 to 22 June
2018. The symposium took place at the Faculty of Civil and Industrial
Engineering of the Sapienza University of Rome, Italy, in the ancient Chiostro
of the Basilica of S. Pietro in Vincoli.
was attended by 119 participants from 30 countries who contributed 120 papers
(83 oral presentations and 37 posters). The scientific program of the symposium
was organized in 10 sessions that were mainly modelled thematically after the
ICCT study group topics and mostly convened by their chairs:
Geodetic methods in Earth system science (N.
Theory of multi-GNSS parameter estimation (A.
Khodabandeh, M. Crespi)
Digital terrain modelling (R. Barzaghi)
Space weather and atmospheric modelling (K.
Börger, M. Schmidt)
Global gravity field modelling and heights
systems (D. Tsoulis, S. Claessens)
Theory of modern geodetic reference frames and
Earths rotation (Z. Altamimi)
Deformation and gravity field modelling at
regional scales (J. Huang, Y. Tanaka)
Estimation theory and inverse problems in
geodesy (A. Dermanis)
Advanced numerical methods in geodesy (R.
Multi-sensor and time series data analysis (W.
Kosek, K. Sosnica)
special session at the Accademia dei Lincei (the oldest scientific academy in
the world, established in 1603 by Federico Cesi) was held on 19 June 2018. Its
program consisted of 6 invited talks focused on interactions of geodesy and
oceanography (M. H. Rio)
glaciology (O. Francis, T. van Dam)
atmosphere (R. Pacione, J. Doua)
mathematics (W. Freeden, F. Sansò)
solid Earth system structure from space (R.
seismology (A. Peresan, M. Crespi, A. Mazzoni, G.
session was organized by Fernando Sansò, Emeritus at the Politecnico di
Milano, member of the Accademia dei Lincei and long-term driving force behind
the Hotine-Marussi symposia series.
program of the symposium was complemented with a social program including a
night tour of the Vatican Museum and the Sistine Chapel.
Hotine-Marussi Symposium was successful also due to the effort and organization
skills of the local organizing committee chaired by Mattia Crespi (Rome), the
vice-president of ICCT. The Hotine-Marussi symposium has been hosted by the
Sapienza University of Rome already for the third time in a row with Mattia
chairing the local organizing committee in all three cases.

of the IAG Inter-Commission Committee on Theory
UN-GGIM seeks to promote international
cooperation in the field of global geospatial information management, and as
the relevant body on geospatial information management in the United Nations,
to report on all matters relating to geography, geospatial information and
related topics such as the Global Geodetic Reference Frame (GGRF).
meeting of national representatives and senior executives from Member States'
national geospatial information authorities, and geospatial information experts
continued to enhance the collaboration, coordination and coherence in global
geospatial information management. Led by Member States, the Committee of
Experts aims to address global challenges regarding the application of
geospatial information, including in the development agendas, and global
policymaking in the field of geospatial information management. In this context
geodesy plays a major role through its Global Geodetic Reference Frame (GGRF)
and IAG is participating as an observer in all meetings and related activities
of UN-GGIM. This year, a Road Map for the Global Geodetic Reference Frame
for Sustainable Development Implementation Plan presented by the UN-GGIM
Subcommittee on Geodesy was discussed at the UN-GGIM session. IAG was
represented by its President Harald Schuh and Michael Pearlman,
Chair of the GGOS Bureau of Networks and Observations (BNO). The Intervention
that was made by IAG reads as follows:
Delegation Intervention for the GGRF Agenda Item - 2018
International Association of Geodesy commends the work done by the UN GGIM
Subcommittee on Geodesy, and emphasizes that the Roadmap Implementation Plan is
an important building block to determining a sustainable Global Geodetic
with its geodetic services, IAG encourages modernization of geodetic
infrastructure, as well as development of Core Observatories, especially in
notes that there is a clear need for strengthened intergovernmental mechanisms
in support of global geodesy, and notes with appreciation the Subcommittee on
Geodesys efforts to provide this through a Convention or other possible
governance mechanisms mentioned in the Position Paper on Governance.
encourages the establishment of funding mechanisms for global geodesy, in order
to support geodetic infrastructure and education in developing Member States.
IAG further notes that such funding will provide a means to strengthen the GGRF
overall, as well as help realize the geodetic contributions to the UN
Sustainable Development Goals and Sendai Framework for Disaster Risk Reduction.

Geodesy can be downloaded at http://ggim.un.org/meetings/GGIM-committee/8th-Session/documents/E-C.20-2018-6%20Global-geodetic-reference-frame-report.pdf.
