Monitoring deforestation across the globe is important for understanding macro-scale impacts on carbon sequestration and climate change. Using approximately 2,000 hand-labelled sites scattered across every continent and coarse resolution (500-m) surface reflectance products from the Moderate Resolution Imaging Spectroradiometer (MODIS) satellites, we created a dataset of time windowed features using seven different spectral bands and used these features to train a binary forest classification model to monitor forest change. Our model achieves an estimated accuracy of 95%, a user’s accuracy (recall) of 79%, and a producer’s accuracy (precision) of 95%. Though the model can be applied across the globe, we scored it on a particular area of interest - the State of Mato Grosso in Brazil, which has seen intense deforestation over the past several decades. We mapped and visualized forest change in Mato Grosso over the past 17 years.
