[IGSMAIL-6430] Modern Height Reference Systems at AGU Fall Meeting 2011

[Chris Jekeli]

Dear Colleagues

Please excuse multiple mailings.

The upcoming AGU Fall meeting, 5-9 December 2011, includes the Session 
G12: Modern Height Reference Systems.  Please consider contributing to 
this important topic.  The deadline for abstract submission is 4 AUGUST 
2011.  The Session Description follows.  See also: 
http://sites.agu.org/fallmeeting/scientific-program/session-search/313.

Description: Hurricanes, earthquakes, and tsunamis wreak havoc with the 
geodetic control needed to re-build, assess damage, and mitigate the 
destruction from future events. Other natural and anthropogenic surface 
deformations demand frequent updates in control. Rapidly 
re-establishing vertical control relative to the geoid requires an 
accurate gravity model. Ongoing infrastructure modernization in the 
U.S. and worldwide is challenged by these problems at the cm level. The 
focus is on new methods to define, realize, and maintain precision in 
vertical datums, including new paradigms that eliminate tide gauge 
references, and that address the needs for civil and scientific 
applications. Datum unification and continuity with previous 
definitions are additional topics of interest.

Thank you.

Sincerely yours,
