The Fall Meeting of the American Geophysical Union (AGU) is held each December in San Francisco. It is one of the largest gatherings of geoscientists in the world, with over 15,000 attendees. Over the past couple of years a quick tour through the poster presentations on any day would have revealed the influence that KML, Google Earth and Google Maps are having on how geoscientists present their data.

In 2006 and 2007 we convened a Virtual Globes session at the AGU Fall Meeting to provide an interdisciplinary forum for those interested in demonstrating their use of geobrowsers, and meeting other like-minded individuals. Previous presenters have included industry developers and bloggers, as well as the authors behind many of your favorite geoscience KML files, such as the volcano layer, earthquake locations, and sea-ice coverage. The sessions are a mixture of talks and interactive demonstrations, with the latter providing large plasma screens, poster board displays and high-speed internet for each presenter.

The 2008 Fall Meeting of AGU will be held on 15-19 December, and with the help of the Google Geo-team we will once again be convening a Virtual Globes session to demonstrate and promote the development and use of virtual globes and KML. We are currently soliciting presentations from scientists, developers, educators and any individuals interested in utilizing these technologies for better scientific understanding, public outreach and education about our "real" world. The deadline for submissions of abstracts is 10th September 2008.

Full details of how to submit your abstract for consideration are available on our 2008 Virtual Globes website, along with links to more info on the rest of AGU's 2008 Fall Meeting. For those just wishing to attend and not present, the full schedule of Virtual Globes talks and demonstrations will be posted on our website in mid-October.
