Geospatial data for Africa: the Brazilian contribution Gilberto Câmara Director, INPE (23 September 2008)

The fundamental question of our time fonte: IGBP How is the Earth’s environment changing, and what are the consequences for human civilization?

Global Change Where are changes taking place? How much change is happening? Who is being impacted by the change?

INPE´s vision for the future A constellation of satellites and sensors will provide free earth observation data for all countries on Earth

“A few satellites can cover the entire globe, but there needs to be a system in place to ensure their images are readily available to everyone who needs them. Brazil has set an important precedent by making its Earth-observation data available, and the rest of the world should follow suit.”

CBERS as a global satellite CBERS ground stations will cover most of the Earth’s land mass between 30 0 N and 30 0 S

“If Brazil can do it, US can do it too”

INPE’s space technology agenda “Global EO” – Brazil as global player in earth observation Multilateral Agreements (CEOS, GEO) Bilateral agreements (China, Germany, UK)
