Google Earth Outreach supports non-profit organizations in certain countries
Google Earth Outreach supports non-profit organizations that share our mission of community service in areas such as education & culture, environment & science, current affairs, global development, public health and social services. As a non-profit organization you can use Google Earth Free to view and create KML files. You can post those KML files on your site or email them to your partners, donors, volunteers, and beneficiaries. You may not use Google Earth Free in the course of providing a paid service to other companies or organizations.
As a part of Google Earth Outreach, we grant Google Earth Pro licenses to qualifying organizations. Google Earth Pro has powerful authoring features which allow for GIS data importation such as .shp and tab files, a movie making module, and a high resolution printing feature.
But unfortunately the program seems to be restricted to certaim [industrialized] nations, Brazil, France, Germany, Italy, the Netherlands, Spain, Switzerland, and the United States, see http://earth.google.com/intl/en_uk/outreach/program_details.html
