Google Earth EDU grants Google Earth Pro licenses to qualifying institutions who demonstrate a compelling need for the advanced features of Google Earth Pro. If you are curious about the differences, Google provides a feature comparison matrix of Google Earth vs. Google Earth Pro.
According to their Web site, the Google Earth Pro Grants program does not grant Google Earth Pro to individual students; only institutions may apply.
Are you already using Google Earth Pro? , I’m curious to know how you are using it. The UW-Madison Center for Sustainability and the Global Environment (SAGE), for example, recently profiled their own use of Pro in the Google for Educators discussion group.
