A behind-the-scenes video reveals how Google worked with the Amazonas Sustainable Foundation and community members to photograph and map the Amazon Basin. Mounting their specialized cameras on boats and a grownup-sized tricycle, they captured gorgeous, detailed images of the landscape. It's truly surreal to click your way through the rainforest and across the water. 

The Google blog includes more background: 

Many areas of the Amazon, including Rio Negro Reserve, are under the protection of the Brazilian government with restricted access to the public, so we hope that this Street View collection provides access to this special corner of the planet that many of us otherwise wouldn’t have the chance to experience. Together with FAS, we’re thrilled to help everyone from researchers and scientists to armchair explorers around the world learn more about the Amazon, and better understand how local communities there are working to preserve this unique environment for future generations.
