Frontiers in Forest Monitoring: The Science Behind Forest Change Data

Thanks to innovations in satellite monitoring, we’ve never had a better understanding of when and where forests are changing around the world. Global Forest Watch (GFW) provides the most up to date forest data available online for free, offering unprecedented transparency on the state of forests worldwide.

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 the GFW Map.

What about the detection of forest pests like bark beetles, can we use the time series imagery to detect forest mass loss due to its attack and differentiation of fire or human deforestation?
