It is available in different formats from the IAG new internet site: http://www.iag-aig.org

Each IAG Newsletter includes several of the following topics:

I.        news from the Bureau Members

II.      general information

III.    reports of IAG symposia

The International Service for the Geoid (ISG)

 

President: Mirko Reguzzoni, Director: Giovanna Sona

 

The International Service for the Geoid (ISG), hosted by Politecnico di Milano in Italy, was founded in 1992 as a working arm of International Geoid Commission (IGeC). It is currently an official service of the International Association of Geodesy (IAG), and is also related to the works of the IAG Commission 2 on Gravity Field. Its activities are coordinated by the International Gravity Field Service (IGFS), established in 2003, that integrate the broader gravity field researches of the: International Service for the Geoid (ISG), International Gravimetric Bureau (BGI), International Geodynamics and Earth Tide Service (IGETS), International Centre for Global Earth Models (ICGEM) and International DEM Service (IDEMS). ISG's activities are on educational, research, and data distribution sides: the principal purposes of ISG are the collection and distribution of geoid models, the collection and distribution of software for geoid computation, and the organization of technical schools and specific trainings on geoid determination techniques.

One of the main task of ISG is to collect, analyse and redistribute local, regional and continental geoid models, keeping its on-line repository constantly updated, and providing also software for estimating and handling geoid models. Public and on-demand regional geoid models are distributed with a unique ISG ASCII format. Basic information and references are provided for all regional models in the geoid repository, that recently exceeded the number of 150.

As regards research activities, ISG participates to international projects and working groups with the aim of improving methodologies for the determination of the geoid at global and local level. Among the others, ISG took part in the European Gravity Geoid Project, the International ESA Gradiometric Mission (GOCE), the Global Geodetic Observing System project (GGOS), the International Height Reference System project (IHRS) for the height datum unification, computation of improved geoids for Italy and the Mediterranean area GEOMED-2 project (2015-2017).

ISG staff is formed by four senior scientists (including president and director), four other scientists expert in Geodesy and one secretary. Moreover a group of ten international geodesists compose the ISG advisory board.

Within the structure of ISG, Working Groups can be established for specific purposes, limited in time.

A technical publication is edited, the IGeS Bulletin, transformed in 2003 into the Newton’s Bulletin, and published in cooperation with the International Gravimetric Bureau (BGI). The Newton’s Bulletin has a technical and applied nature and it has been recently selected by the geodetic community for publications on the assessment of EGM2008 and GOCE global gravity models. On the website www.isgeoid.polimi.it all the issues of the Bulletins are available.

As mentioned, the Service has also educational purposes: one of the main tasks of ISG consists in organizing or supporting technical schools on geoid estimation and related topics, held possibly every two years.

The First International School for the Determination and Use of the Geoid was organized in Milan in 1994, and since then many other editions of the School followed, held in many countries, with the support of local organizing committees.

The following table shows the years, the locations, the number of participants and the number of involved countries of the past editions of the International Geoid School :

During the schools both theoretical and practical aspects are illustrated, and students are trained in the use of the relevant software for geoid computation. The general purpose of the full-week intensive Geoid School is to prepare new graduate students, young scientists, employees of national agencies and services or industry staff, to compute and use gravimetric geoids for scientific and technical applications in geodesy, primarily in transforming ellipsoidal (GPS) heights into orthometric ones. The School provides a good opportunity to familiarize with the latest development in geoid determination, and to improve international contacts and collaborations among scientists dealing with gravity field modelling.

The School is structured in a way to be self-contained for any participant at graduate level with basic knowledge of geodesy. During a full week, theoretical lectures are followed by computer exercises based on the available software, according to the following general scheme:

 

ˇ         introduction to physical geodesy and to collocation theory in geoid computation;

ˇ         computation and use of high degree and ultra-high degree geopotential models;

ˇ         geoid computation using Stokes’ integral;

ˇ         terrain effects in geoid estimation;

ˇ         FFT techniques in geodesy.

ˇ         some seminars on specific topics (e.g. height datum unification).


Lecture notes of the courses are distributed to the participants as well as a CD containing software and exercises. The CD containing software and examples on geoid computation, as well as the lecture notes, can be requested through the ISG website, under the same restrictions applied when distributed during the geoid schools: freely available after a declaration stating for non commercial use of the software.

In addition to the International Geoid School, ISG gives support to foreign institutions and scientists in the field of geoid computation, by organizing, on request, specific training courses on geoid computation held at Politecnico in Milan.

The most recent educational cooperations have been :

 

ˇ         Support to the National Geophysical Research Institute of Hyderabad (India) in computing a gravimetric geoid in South India.

ˇ         Training course on geoid computation procedures, held in June 2011, attended by three researchers of the Center of Geodesy and Geodynamics of Nigeria (Center of Geodesy and Geodynamics-National Space Research and Development Agency).

ˇ         Local gravity model estimation over Bangladesh, based on GPS/leveling points locally collected, in cooperation with a researcher of the Survey of Bangladesh hosted at ISG in Milano, in February 2009, with individual training course.

ˇ         Training course on geoid computation, held in November 2015, attended by two researchers of the Service of Surveying-National Institute of Cartography of Cameroon.
