Global Forest Watch (GFW) is an open-source, cloud-based forest monitoring platform that leverages advanced GIS technology and satellite-derived geospatial data to track deforestation, forest degradation, and land-use change in near real-time across the globe. Developed through a partnership led by the World Resources Institute, GFW integrates multi-temporal remote sensing imagery, spatial analysis algorithms, and interactive mapping tools to detect and visualize forest cover loss and gain at regional, national, and subnational scales.

From a GIS perspective, the platform applies raster-based spatial analysis techniques to high-resolution datasets, including NASA MODIS and Landsat imagery, enabling analysts to query, classify, and interpret forest dynamics with measurable precision. Users can perform custom geospatial queries, generate temporal change maps, and export datasets for integration into external GIS environments such as ArcGIS or QGIS.

The practical benefits include empowering governments, conservation organizations, and land managers with actionable intelligence for environmental policy, carbon accounting, and biodiversity protection. By combining geospatial data infrastructure with accessible visualization tools, GFW represents a scalable model for applying GIS to critical global environmental challenges.
