Visualization plays a critical role in teaching and learning about the Earth. All geoscience students must be able to mentally transport themselves to a different time and place, work across multiple scales of time and space, and visualize their environment as viewed from different perspectives. Geospatial visualization resources for teaching and learning are at the heart of the Google Earth for Onsite and Distance Education (GEODE) project. Specific foci of this project included enhancements to virtual globes such as Google Earth that allow for plate tectonic reconstructions, embedded virtual specimens and outcrops, interactive imagery, "grand tours" of the Earth (and other planets and moons), and learning modules using large geoscience datasets.
