   <td>Calit2's Albert Yu-Min Lin has been named to the 2010 class of National Geographic Emerging Explorers. His current research interest is to find the tomb of Genghis Khan in Mongolia, albeit without physically turning a single rock, but only by analyzing a variety of data modalities such as satellite imagery, aerial photography, and sub-surface radar. This demonstration shows three scanning modalities in one visualization application: magnetic, electro-magnetic, and ground penetrating radar. The latter is able to penetrate the ground the deepest, so we chose to focus on it when it comes to visualizing depth data. Spheres with a depth-based color scheme are used to visualize the data. The user can interactively select how deep they want to go under ground, and then fly around to examine the data and put it in perspective with the other two modalities.</td>

This application shows high resolution aerial data of the areas affected by the fires. The data resolution is extremely high at 0.5 meters for the imagery and 2 meters for elevation. Our demonstration shows this data embedded into an osgEarth-based visualization framework, which allows adding such data to any place on our planet and viewing it in a way similar to Google Earth, but with full support for high-end visualization systems.</td>

Kyle Knabb has been working with the IVL as a master's student under Professor Thomas Levy from the archaeology department. He created a 3D visualization for the StarCAVE which displays several excavation sites in Jordan, along with artifacts found there, and radio carbon dating sites. The data resides in a PostgreSQL data bank with the PostGIS extension, which the VR application uses to pull down the data at run-time.
