Use of GEON LiDAR data to validate GEO Grid ASTER-based DEMs China –GEON Workshop, October 2006, Beijing. Co-sponsored by Chinese Academy of Sciences. –Collaborations in developing parallelized geodynamics codes

GEON Workshop, Auckland, Nov 26-27, 2007 International GEON Activities Russia –GEON Workshop, July 2007, Moscow. Co-sponsored by Russian Academy of Sciences –Possible collaborations in grid computing and XML databases India –Joint project with University of Hyderabad, funded by the Indo-US Science and Technology Forum ($100K/2 years) –GEON workshops in October 2005 and August 2007 –Visits by US collaborators to India, and vice versa; visit by Indian PhD student to US; identification of Master’s thesis projects in India –iGEON-India network in India

GEON Workshop, Auckland, Nov 26-27, 2007 GEON 2.0 Use Case Scenario –Derived 3D volumetric model –Multiple isosurfaces, with different transparencies –Slices through the volume –Variable gridding: data typically has lower resolution at greater depths –2D surface data: Satellite imagery, street maps, geologic maps, terrain surface, fault lines, and other derived features etc. –allow a lower layer, such as a gravity map, to show through –terrain can be shown alone, or integrated with volume and interface models to aid correlations. –Bore hole or well data –provides record of the rock types encountered at different depths at a sample location. The data are important in resolving ambiguities in the inferred interfaces from other data. –show sample locations as icons atop the terrain, and as well paths drawn downward through the model –sample locations will be scattered across a region and may provide definitive interface data in only some areas. “For a given region (i.e. lat/long extent, plus depth), return a 3D structural model with accompanying physical parameters of density, seismic velocities, geochemistry, and geologic ages, using a cell size of 10km”
