Despite international efforts to reduce deforestation, the world loses an area of forest that is equivalent to the size of 40 football fields every minute. Deforestation in the Amazon rainforest accounts for the largest share, contributing to reduced biodiversity, habitat loss for many of the world’s most threatened animals and insects, and more rapid climate change.
Satellite remote sensing offers a powerful tool to track changes in the Amazon. The Multimodal Learning for Earth and Environment Challenge (MultiEarth 2022) is the first competition aimed at monitoring and analyzing deforestation in the Amazon rainforest at any time and in any weather or lighting condition. Weather conditions in the Amazon are often humid and cloudy, making it difficult to gather clear images.
In this workshop, learn from Miriam Cha, Research Scientist in the Artificial Intelligence Technology Group at MIT Lincoln Laboratory, about multimodal representation learning for the earth and environment.
Cha will discuss the benefits and challenges of synthetic aperture radar (SAR), a sensor that transmits microwave signals and then receives back the signals that are returned from the earth’s surface. Although SAR images are extremely clear, they can be difficult for humans to interpret due to noise and lack of spatial correlations. This is why MultiEarth 2022 is using SAR with optical sensors for maximum effect.
