
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




The downlink data is open to any country or
organization.

The data downlink for CBERS will be carried out through
a ground station.

China and Brazil may, in a few special cases, upon
mutual consultation, decide on the transfer of data free
of charge.

The revenues resulting from the distribution of CBERS
data will be equally shared between China and Brazil.
Policy for CBERS International Data Downlink

Access fee is charged on a LANDSAT-like basis

One flat annual fee for complete access to all data in the
antenna’s footprint

Distribution in areas within the antenna’s footprint is the
responsibility of the ground station operator

There is no additional charge for image distribution

Ground station operators are encouraged to distribute
CBERS data free of charge on the Web

Modelling Deforestation in Amazonia

High coefficients of multiple determination were obtained on all
models built (R2 from 0.80 to 0.86).

The main factors identified were:





Population density;
Connection to national markets;
Climatic conditions;
Indicators related to land distribution between large and small farmers.
The main current agricultural frontier areas, in Pará and Amazonas
States, where intense deforestation processes are taking place now
were correctly identified as hot-spots of change.
