The Levallois Medal was established by the International Association of Geodesy in 1979 to honour Jean-Jacques Levallois, and to recognize his outstanding contribution to the I.A.G., particularly his long service as Secretary General, 1960-1975.
The award of the Medal will be made in recognition of distinguished service to the Association, and/or to the science of geodesy in general.
The Medal is normally awarded at four year intervals, on the occassion of the General Assemblies of the International Association of Geodesy and International Union of Geodesy and Geophysics; but the award may be omitted if it is considered that there is no candidature of sufficient merit, and an additional award may be made at any time if justified by exceptional circumstances.
A nomination for the award shall be made by an ad hoc committee consisting of the Honorary Presidents and must be confirmed by the I.A.G. Executive Committee. The ad hoc committee shall prepare a citation, suitable for publication, setting out the grounds for the proposed award before the General Assembly.
