  1. Virtual Globes by: Steven Wood Dept of Science Wheeler School

  2. Virtual Globes • A virtual globe is a 3D software model or representation of the Earth or another world.

  3. Projected on a Globe Image Draped over digital Topography

  4. What A Virtual Globe Can Do For You! • You can look at the globe from different perspectives.

  6. Why Are Virtual Globes Useful In the Classroom • Its is a VISUAL learning tool. Allowing students to visualize concepts that we often teach them verbally. • It is an INTERACTIVE program which the student can freely access and easily manipulate, allowing them to formulate there own questions on a concept and search out the answers to them • It creates an ENGAGING learning environment, bringing elements commonly used to attract students to video games into use in attracting them to explore and learn

  7. Examples Of Virtual Globes • NASA World Wind- educational focus, open source, Measuring tools, lots of layers. • Google Earth- commercial focus, high resolution-most recent data, widely used, linked with other google tools • Microsoft Virtual-Earth- Wants to compete with Google earth • ARC-GIS Explorer- GIS on a virtual Globe

  8. Two Versions of World Wind • World Wind .net • Original version of World Wind • Runs only on PC • Most flexible version • Has lots of layers • Has many options and add-ons • World Wind Java • Still in development • Works across platforms (Mac or PC) • Can be imbedded in web pages • World-Wind versions customized to your use can be produced.
