" FYI ref Landsat Business model:
NASA's Lawrence Fridl on the Landsat Business Model: "The open data sharing policy is a foundation of the Landsat business model. In 2008 USGS made all, now, 3.7 million satellite images freely available to the public. Besides following a use-taxpayers-money-only-once principle, it was believed that the increased accessibility would inspire more innovative projects both publicly and privately. And the use of Landsat data exploded. From some 25000 downlinks pr year to 3 million downlinks! In some ways it is similar to the freemium business model. It works. Although the largest user group are governmental improving services within homeland security, water management etc, there are some major enterprises to be found as well. Google is one of the most prominent users of Landsat data but we have also seen innovations like ESRI's ChangeMatters [http://changematters.esri.com
Lawrence Fridl is one of the GEO community's ambassadors for showing the socio-economic benefits from Earth observations.

It is equally interesting to see the recent joint announcement from NASA/USGS and ESA on closer collaboration between Landsat 8 and the ESA Sentinel missions. Sentinel's data policy is belowfrom a presentation made by the European Space Agency at a workshop in January 2012:
Sentinel Data Policy = full and open access to Sentinel data to all users
• Aim for maximum availability of data & corresponding access services
• Support to increasing demand of EO data for climate change initiatives implementation of environmental policies In practical terms
• Anybody can (has the right to) access acquired Sentinel data
