The GGOS Contribution to GEOSS and an Observing System for Geohazards and Disaster Prevention

A GEO Workshop organized by the Global Geodetic Observing System (GGOS)

November 5-6, 2007
Frascati, Italy
A Contribution to the International Geohazards Week


Last edited 22 February 2008

The 2007 GEO/GGOS Workshop was organized as part of the International Geohazards Week (IGW). The Web Page of the IGW was hosted by the European Space Agency at http://earth.esa.int/workshops/2007Geohazards/. Registration, hotel reservation, and abstract submission were facilitated through this common page. Here, additional information on the Workshop background and program was provided. This page gives now also access to the presentations given at the Workshop and a brief Workshop summary report.

Workshop Background and Objectives

The Global Geodetic Observing System (GGOS) of the International Association of Geodesy (IAG) is coordinating the geodetic support for the Earth sciences. Building upon the work of the IAG Services, GGOS provides the geodetic infrastructure necessary to support the monitoring of the Earth system and global change research. It is integrating the three pillars of geodesy, that is geometry and kinematics, Earth orientation and rotation, and gravity field and dynamics, in order to maximize the benefit for the scientific community and society in general.

With the global geodetic reference frames and observations of the variations in the Earth's shape, gravity field, and rotation, GGOS provides fundamental contributions to the Global Earth Observation System of Systems (GEOSS). In a detailed strategy process carried out in the frame of the GEO Work Plan (Task AR-07-03), GGOS is currently developing the plan for a geodetic observing system that will meet future requirements not only of GEOSS but also of science and society in general. To a large extent, the Workshop was based on the results of the strategy process and discussed implictly steps towards the implementation of the recommendations given in the strategy report.

The 2007 GGOS Workshop was integrated into the International Geohazards Week 2007. The GGOS Workshop was intended as an outreach activity of GGOS to both the space agencies and users. The Workshop discussed the current and future contributions of GGOS to Earth observations and, in particular, an observing system for geohazards applications. The Workshop was organized to help facilitate the communication between scientific user communities and those who will provide the geodetic products. Therefore, the Workshop was held in conjunction with the Third International Geohazards Workshop, organized by the IGOS-P Geohazards Theme, which took place after the GGOS Workshop.

Workshop Venue

The GEO?GGOS Workshops took place at ESRIN in Frascati, Italy. More information on the venue is still available through the IGW Page.

Workshop Program

The Workshop Program was organized in three main sessions:

  • Session 1: Observing changes in Earth's shape, rotation and gravity field with an integrated observing system;
  • Session 2: Understanding the Earth system: The contribution of GGOS;
  • Session 3: GGOS and Geohazards.
More information on the program is available here.

Program and Organizing Committee

The Program and Organizing Committee had the following Members:

  • Markus Rothacher, GGOS, Chair of GGOS Steering Committee
  • Hans-Peter Plag (Chair), GGOS, Vice-Chair of GGOS Steering Committee
  • Ruth Neilan, GGOS, Vice-Chair of GGOS Steering Committee
  • Michael Pearlman, GGOS Executive Committee
  • Chopo Ma, GGOS Executive Committee
  • Susanna Zerbini, GGOS Executive Committee
  • Bente Lilja Bye, Chair of GGOS WG on Outreach and User Linkage
  • Goneri Le Cozannet, IGOS Geohazards Bureau
  • Marc Paganini, IGOS-P Geohazards, European Space Agency
  • Osamu Ochiai, Group on Earth Observation (GEO)
Questions related to the Workshop should be sent to Hans-Peter Plag.


  • April 5, 2007: First Circular
  • April 20, 2007: Registration and abstract submission opening
  • August 31, 2007: Deadline, submission of abstract
  • October 20, 2007: Deadline, registration

Abstract Submissions and Proceedings

Abstracts for oral presentations and posters were accepted up to end of September 2007. The abstracts were included in a Book of Abstract covering all four events at the IGW. This Book was distributed to all participants of the various events during the IGW.

Abstract submission was through the IGW Page. Most oral presentations were invited.

It was intended to produce common electronic proceedings of the events at the IGW, most likely on a CD and a web page. Manuscripts to be included in the proceedings will have to be uploaded to a specific site during the IGW at ESRIN.

Registration and hotel reservations

Registration and support for hotel reservation was available through the IGW Page. The registration fee for the Workshop was originally set to EUR 100, but this fee was subsequently waived by ESA. All those who paid the fee were refunded during the workshop.


The official language of the workshop was English. Participants were expected to finance their own travel and accommodation.
