GEO WG updatesPRAGMA17@Hanoi

Resource WG established the GEO group in PRAGMA VO

• GEO WG members easily make registration

• Registered members can access to ASTER and Formosat-2 data as demonstrated by Naotaka yeseterday

Geoscience WG

• Day 1– “Computational solution to the air

pollution physics & chemistry in modern dense & compact cities” by Wai Chi CHENG, The University of Hong Kong

– Ekasit Kijsipongse, NECTEC , Thailand– A.B.M. Russel, VeRSI– “Satellite-Field Data Integrator” by

Sarawut Ninsawat, AIST, Japan– “Update of 3D-GIS Taiwan”, NARL

Joint session of Telescience and Resource WG

– SOS interoperability experiments with more GLEON sites and LiveE!

– GPS mobile-phone as a sensor– How to register GLEON users in PRAGMA

VO to promote more collaboration?– More collaboration with another community?

(Next PRAGMA will be held at San Diego with Coral Reef Observation Network=CREON)

Day 2:

GEO Grid VO design

OGC standard (GEO/Telesciences)
