Geodesy Section News
The Geodesy Section of the Canadian Geophysical Union had
an important series of activities during the past Canadian Geophysical
Union/American Geophysical Union Joint Meeting 2004, held in Montreal, May 17-21, 2004: Meeting of the Executive, Annual General
Meeting, Student Paper Competition and the Eighth Geoid Workshop.
During the Annual General Meeting, the Executive for 2004-2006
was elected. The executive is:
President: Prof. S. Pagiatakis (York University)
Vice President: Dr.
C. Klatt (NRCan, Geodetic Survey)
Secretary: Prof.
M. Santos (University of New Brunswick)
Treasurer: Prof.
R. Blais (University of Calgary)
Members-at-Large: Dr.
H. Dragert (NRCan, Geological Survey)
Prof.
N. Sneeuw (University of Calgary)
There were eight student papers competing for
the $500 prize awarded by the Geodesy Section sponsored by the Geodetic Survey
Division of NRCan. The winner was Mr. Rodrigo Leandro, a PhD student from the
Department of Geodesy and Geomatics Engineering, University of New Brunswick. The competing papers were:
- Mohamed El-Habiby: Linear
versus Non-Linear Least Squares Adjustment with emphasis on the 3-D
Coordinates Transformation Problem
- Robert Kingdon: Calculation of the
spherical terrain correction to Helmert’s orthometric height
- Azadeh Koohzare: Glacial
Isostatic Adjustment Observed using Historical Tide Gauge Records and
Precise Relevelling Data in Eastern Canada
- Mazhar Rafiq: Study of Eastern
Canadian coastal site displacement due to ocean tide loading using a GPS
network in Atlantic Canada
- Matthias Weigelt: CHAMP
Gravity Results using the Energy Integral Approach with Emphasis on
Algorithmic Aspects
- Huaining Yang: Atmospheric
effects in the three-space scenario for the Stokes-Helmert Method of geoid
determination
- Chen Xu: Satellite Formation
Flying for Geodetic applications: Analysis of J2-Disturbed Orbits
The
Eight
Geoid Workshop was an activity
that took place on 16 May 2004, the Sunday before the AGU/CGU
Meeting. This year, the Workshop was mostly taken by presentations and
discussions related to two GEOIDE/NCE projects, namely “Seamless Vertical
Reference System for Geomatics Applications,” and “Precise Geoid
Determination.” Several geodesy students from all over Canada participated, giving presentations
and contributing to the discussions. There were also discussions on three
approved GEOIDE/NCE projects (pending on the extension of the Network): “Mapping the ocean surface with geodetic and oceanographic
tools”, “Space
gravimetry contributions to Earth monitoring” and “Next-generation algorithms for navigation, geodesy and earth sciences
under modernized Global Navigation Satellite Systems (GNSS)”. A picture of the
participants of the Workshop is shown below.
