1. Earth observation data for everyone: the CBERS experience Gilberto Câmara Director, National Institute for Space Research

2. The need for global land observation The world is changing rapidly  Climate Change is here to stay Global land observation is a crucial need for the world, but its future is uncertain  MODIS is very useful,but has no future  What will happen to LANDSAT? Global land observation systems are a public good

13. The 300+ million dollar question How do we obtain support for funding Earth Observation Missions? Our answer: Make all sectors of society use publically funded EO data......by providing EO data for free!

14. Uncle Scrooge and the Internet Uncle Scrooge: “A penny saved is a penny earned” The anti-Uncle Scrooge principle: “A pixel saved is a penny wasted” Why is that so?

15. The Internet paradox The Internet has reduced the cost of data distribution to very close to zero Society responds very quickly to open availability of free data and good on the Web

16. Brazilian and Chinese Strategy for CBERS CBERS images received in Brasil are freely available on the Internet for Brazilian and Latin American users CBERS images received in China are freely available on the Internet for Chinese users A high-quality image processing software (SPRING) is also available free on the Internet in Brazil

17. CBERS: China-Brazil Earth Resources Satellite Brief History  Initial agreement signed in July 6th, 1988, covering CBERS-1 and 2.  In 2002, both governments decided to expand the initial agreement by including CBERS-3 and 4. Program objectives  Build a family of remote sensing satellites to support the needs of users in earth resources applications  Improve the industrial capabilities of space technology in Brazil and China

41. What do we get from free data? “With zero cost data access, technology dissemination has a much greater impact.” “CBERS brought the freedom to have data immediately available when you need it.” Free EO data and free EO technology create new users and new applications Increases the need for other types of EO data

42. What do the private companies say about free CBERS data? Enables new business development Facilitates trial uses for new clients Planning new applications becomes easier Creates jobs by reducing cost of data buys Increases work quality by adding data previously unavailable

43. What have we learned? There is an enormous demand for remote sensing data in developing countries Free on-line data access can significantly increase the number of users of earth observation data The CBERS data policy has been extremely well-received by government and society in Brazil

44. One world, one dream... Free Earth Observation data for all!

45. One world, one dream... A consortium of Earth Observation satellites for global land observation (5m+) A network of cooperating ground stations EO data free on the Internet, with global weekly coverage

47. Key questions (Donna Coutts and Achache) How do we develop services from Earth Observation data? How does the system change when everyone has ready access to space-based Earth observation?

48. Key questions (Donna Coutts and Achache) How do we develop services from Earth Observation data? How does the system change when everyone has ready access to space-based Earth observation? Create a market for services and high-resolution data by providing EO data at a massive scale!
