<p>Experts from GFW and the University of Maryland (UMD) Global Land Analysis & Discovery (GLAD) Lab provide an overview of the methodology behind core forest change datasets on GFW, including the GLAD deforestation alerts and annual tree cover loss data. From satellite imagery pre-processing steps, to determining the likelihood of forest disturbance, you’ll gain a deeper understanding of how we get from a satellite image to the pink pixels displayed on GFW’s map. The webinar is available in English and Spanish.</p>
