GFW is free for all and very easy to use. If you can use Google maps to find a local shop then you can use GFW to uncover what is happening to forests in your neighborhood or on the other side of the world.

Application highlights include:

Easy to use: No technical expertise is needed to start using GFW.

The crowd: GFW brings together high-resolution information from satellites with the power of crowdsourcing.

High-resolution: Annual tree cover loss and gain data for the entire globe at a resolution of 30 meters (University of Maryland/Google derived from NASA/USGS Landsat).

Near-Real Time: Monthly tree cover loss data for the entire humid tropics at a resolution of 250 meters. (FORMA derived from NASA’s MODIS).

Partnership: GFW was developed by a diverse set of partners and collaborators that have converged around the goal of transparency and open data to support better forest management. These include: technology firms (Google, ScanEx, and ESRI), businesses (Unilever and Nestle and the wider TFA 2020 Partnership), international organizations (UNEP, GEF), leading NGOs (CGD, Imazon, Transparent World), and many others.

Speed and cost: Cloud computing provided by Google reduces the costs of maintaining GFW, while multiplying the speed at which data can be analyzed.

Technology and human networks: GFW uses the latest technology from Google and NASA combined with a network of partners around the world to build a global movement.

How Can People Use Global Forest Watch?

Governments can design smarter policies, better enforce forest laws, detect illegal forest clearing, manage forests more sustainably and achieve conservation goals.

Indigenous communities can upload alerts and photos for all to see when encroachment occurs on their customary forest lands.

Buyers of major commodities such as palm oil, soy, timber, and beef can better monitor compliance of their suppliers with relevant laws, commitments, and certification standards.

Suppliers of these commodities can more credibly demonstrate that their products are “deforestation free” and legally produced.

NGOs can identify deforestation hotspots in near-real-time, mobilize action, and collect evidence to hold governments and companies accountable for forest-related commitments.
