AI BriefingCreating a new satellite imagery map to protect Brazil's forests
Key point
Google has released a high-resolution satellite map of Brazil as of 2008 to help protect its forests.
Details
In the early 2000s, Brazil experienced record-breaking deforestation, facing biodiversity loss and rising temperatures. Google partnered with the government to create the first high-precision satellite imagery map showing Brazil's national territory from that period, and this data is now available to everyone on Google Earth and Earth Engine.
The map was completed by processing thousands of past satellite images, removing clouds, and performing color correction. It is up to 6 times more precise than previously available imagery, making it possible to see fine patches of forest more clearly for the first time.
As a result, local authorities can now more precisely determine exactly where deforestation is occurring. This enables a level of tracking and response that was previously impossible, and serves as a new baseline for measuring progress on protection policies.
