150 Years International Association of Geodesy

 

The International Association of Geodesy (IAG) is celebrating its 150th anniversary in 2012. At the invitation of the Prussian General Johann Jacob Baeyer (1794-1885), representatives of the states of Prussia, Austria and Saxony met from 24th  to 26th April 1862 in Berlin to discuss Baeyer’s “Proposal for a Central European Arc Measurement” (“Entwurf zu einer mitteleuropäischen Gradmessung”), which he had sent out in 1861 to all Central European states. By the end of 1862, 16 states had already agreed to participate in the project: Austria, Belgium, Denmark, France, seven German states (Baden, Bavaria, Hannover, Mecklenburg, Prussia, Saxony, Saxe-Gotha), Italy, The Netherlands, Poland, Sweden and Norway (in personal union), and Switzerland. This was a great success and the start of an organised international collaboration in geodesy. The IAG counts this international scientific (governmental) initiative, and the organisation it spawned, as its origin.

The idea for the project had been submitted by Baeyer to the Prussian Ministry of War in his document “On the size and figure of the Earth: a memorandum on the establishment of a Central European arc measurement, along with a sketch map” (“Über die Größe und Figur der Erde: eine Denkschrift zur Begründung einer Mitteleuropäischen Gradmessung nebst einer Übersichtskarte”). The aim was to connect the numerous Central European astronomical observatories by the existing or to be planned triangulation networks, in order to determine the regional and local anomalies of the curvature of the figure of the Earth (i.e. the deflections of the vertical and thus the relative structure of the geoid). This was the basis for all precise point positioning in science and practice, and the beginning of interpreting these anomalies with respect to the structure and composition of the outer layer of the Earth, which was explicitly mentioned by Baeyer as a scientific challenge.

J. J. Baeyer memorial in Berlin Müggelheim and the first page of the Minutes of the Meeting in 1862

 

In October 1864, the first “General Conference of the Representatives to the Central European Arc Measurement” took place in Berlin. The organisational structure (Permanent Commission, Central Bureau, and triennial General Conferences) was agreed to and a research programme was set up. The IAG considers this conference as its first General Assembly. J. J. Baeyer was appointed Director of the Central Bureau and P. A. Hansen appointed President of the Permanent Commission. The project extended rapidly to other European states, and consequently the name of the organisation was changed in 1867 to “Europäische Gradmessung”, and in 1886 to “Internationale Erdmessung” (in French: “Association Internationale de Géodésie”, in English: “International Geodetic Association”) with additional member states Argentina, Chile, Japan, Mexico, and USA. Baeyer died in 1885, and under his successor, Friedrich Robert Helmert, the Central Bureau moved from Berlin to Potsdam, together with the Geodetic Institute, which is the predecessor of today’s GeoForschungsZentrum (GFZ) Potsdam.

To pay tribute to its origins, IAG will hold its regular quadrennial Scientific Assembly as the official anniversary celebration in September 2013, between the dates of the foundation and first General Conference of the Mitteleuropäische Gradmessung, in Potsdam and Berlin.

Invitation for proposals for changes to the IAG Statutes and Bylaws

 

Article 16 of IAG’s Statutes specifies that the Association shall review its Statutes and Bylaws to ensure an up-to-date structure of its scientific organization every eight years. The last time such a review was initiated was about eight years ago under the presidency of Gerard Beutler. It is now therefore time that we again take a fresh look at our Statutes and Bylaws. To achieve this goal, a Review Committee (traditionally called the Cassinis Committee) was appointed in the fall of 2011 by the IAG Executive. The committee is chaired by Michael Sideris and includes as members Harald Schuh, Ruth Neilan and Yoichi Fukuda. A proposal with all suggested revisions will be made by the Cassinis Committee for consideration by the IAG Executive and possibly the Council at the 2013 Scientific Assembly. In this way, we are hoping to get the Council’s reaction and input to the proposed changes before these are finalized and approved at the next IUGG General Assembly in 2015.

With this announcement, the Cassinis Committee is inviting proposals for changes of any article of the Statutes and Bylaws. Proposals can be submitted through the IAG website Forum (www.iag-aig.org/proposals). The actual Statutes and By-laws can be found on the IAG website.  All proposals submitted between March 1, 2012 and February 1, 2013 will be considered by the Cassinis Committee.

We are very much looking forward to receiving your contributions.

 

Michael Sideris, Harald Schuh, Ruth Neilan, Yoichi Fukuda

For more information on NAG contact Prof. Francis I. Okeke (francis.okeke@unn.edu.ng).

 

Please find below the Communiqué of the Conference:

 

PREAMBLE

The 2011 General Assembly/ Conference of the Nigeria Association of Geodesy (NAG) was held in University of Nigeria, Enugu Campus (UNEC) Enugu, from Wednesday 14th to Friday 16th September 2011 with the theme: National Challenges in the 21st Century and Geodetic Solutions.

The Conference was declared open by the Vice-Chancellor, University of Nigeria, ably represented by Prof. G. O. S. Amadi. Professors F.A. Fajemirokun and D. M. J. Fubara delivered Association lectures on: The future of Geodesy in Nigeria: Issues of Capacity Building; and Space Geodesy in Coastal and Marine Environment respectively.

The Technical Sessions dwelt extensively on the following sub-themes:

i.                     Geodesy, Geo-Hazard Threats and Security Issues in Nigeria

ii.                    Advances in Geodetic Infrastructure Development in Nigeria;

iii.                  Geodesy in Economic, Coastal and Environmental Management in Nigeria;

After  due  deliberations,  the  Conference  arrived  at  the  following  resolutions  and recommendations.

RESOLUTIONS AND RECOMMENDATIONS

1.       Overview of Geodesy in Nigeria

The Conference examined the development and challenges of geodesy in Nigeria form the inception and recommends that Geodesists should go back to drawing board, define priorities and draw up programmes of actions at finding solution to the geodetic challenges.

2.       Geo-hazard Threats and Security Issues

(a)     Geo-hazard:

The Conference expressed satisfaction with the application of Geodetic Solutions to solving geo-hazard problems in Nigeria and recommends the comprehensive use of geodetic techniques in monitoring flood disasters and large structures (high-rise buildings, bridges, dams, oil rigs, oil tanks, etc) in Nigeria.

(b)     Security Issues:

The  Conference  appreciates  the  efforts  made  by  governments  in  boundary demarcations in Nigeria and therefore recommends that all states and national boundaries should properly and physically demarcated and monitored to avoid boundary skirmishes and enhance peace and development in Nigeria.

3.       Geodetic Infrastructure Development

(a)     Space Geodesy:

The Conference appreciates the provision of the Global Navigation Satellite System (GNSS) Continuously Operating Reference System (CORS) in Nigeria by the Federal Government and therefore recommends that more of the infrastructure be deplored to cover the length and breadth of Nigeria; and to invest more on collaborative research on the use of the infrastructure for Land Reform and Space Research and Development in Nigeria.

(b)     Physical Geodesy:

The Conference regretted the paucity of gravity data in Nigeria for Research and Development, which has hampered determination of accurate height data for geophysical and oil/mineral exploration. The Conference therefore recommends that gravity observations already done in Nigeria should be made available to Geodesists for relevant Research and Development.

4.       Economic, Coastal and Environmental Management

The Conference expressed concern on the danger posed by sea level rise around the coastal regions of Nigeria and recommends that the Governments should provide Tides Gauges and other Facilities to Monitor and manage the phenomenon.

5.       Capacity Building

i.                The conference expressed the need for capacity building in all aspect of Geodesy and therefore recommends close collaboration between NAG, NIS, SURCON, OSGOF and NASRDA to tap from the expertise of Nigerian Geodesists.

ii.               The conference observed lack of interest in Geodesy and consequently recommends that NAG should take necessary steps to create the awareness and liaise with necessary institutions to reverse this trend;

iii.             In order to tackle what seems to be lack of interest in the area of Geodesy and Geodynamics, institutions have been challenged proactive and encourage the study of Physics and Mathematics which are the fundamental subjects.

6.       The Way Forward

The Conference observed the following as the way forward in the Institutional, corporate and individual capacity development and utilization of Geodesy in Nigeria.

 

a.       The NAG viewed with concern the plan to jettison Nigeria Geodetic Datum in preference for the Global WGS-84 Geocentric Datum for mapping operations and therefore recommends the need to study the implications of such a decision by High Powered Study Group and take a final position.

b.       Making Centre for Geodesy and Geodynamics (CGG) in Toro a Centre of Excellence;

c.        Resolving all issues relating to Geodetic Control Network (Horizontal, Vertical and Datum Definition);

d.       Government Agencies and other Stakeholders in Geodesy should show more interest in Geodesy by formally challenging Geodesists with National problems and sit in to listen and exchange ideas at Geodetic Conferences.

Appreciation

Finally, we express our appreciation to the Local Organizing Committee (LOC), the sponsors, the Management of Moot Court Hall and the Vice Chancellor University of Nigeria, and the Chairman, NIS (Nigerian Institution of Surveyors) Enugu State. Special thanks to all delegates and participants for their support and maximum cooperation throughout the Conference.
