Google releases AI forest map with annual land-use tracking

Google DeepMind and Google Research released Forest Typology 2020, or ForTy, on October 22. The global map classifies land in 10-meter squares, distinguishing natural forests from plantations and agricultural uses. An accompanying early-release dataset tracks annual changes from 2017 through 2025.

Developed with WRI and IIASA, the map separates primary forests, naturally regrowing forests, planted forests and intensive plantations. It also identifies tree-based agriculture and other land. Google said testing across more than 9,000 sites found 90% accuracy for forest-type classification.

The distinction matters because replacing natural woodland with commercial trees can leave an area looking green while changing its ecological value. The annual dataset is designed to show those transitions, including conversion to plantations or farms.

Both datasets are available through Google Earth Engine with an open license. Google plans to refine the annual series with partners and users over the coming months.
