A new tool called Earth Index allows anyone to scan global satellite imagery by visual similarity, identifying patterns like deforestation or illegal airstrips. Developed by the nonprofit Earth Genome, it uses foundation models trained on vast Earth observation data to automate a process that previously required specialized teams and months of work. The tool is now available without a waitlist through an 'Open' tier, with advanced features offered separately.

Facts First

  • Earth Index allows public scanning of satellite imagery by visual similarity to find patterns like deforestation or airstrips.
  • The tool automates analysis that previously required specialized teams and significant resources.
  • It is available without a waitlist through an 'Open' tier providing global access and core features.
  • Advanced capabilities are offered in a separate tier, including a 'Deep Search' feature and API access.
  • Developers intend to keep access free for high-impact users of the tool.

What Happened

The nonprofit Earth Genome has released Earth Index, a tool that allows users to scan global satellite imagery by visual similarity. Users can highlight an example, such as a patch of deforestation or an airstrip, and instruct the system to find comparable patterns elsewhere. This approach relies on 'foundation models' trained on vast archives of Earth observation data to recognize features across geography and time. Previously, such analysis required specialized teams, bespoke models, and significant computing resources, often taking months to develop.

Why this Matters to You

This tool could empower you to monitor environmental changes or industrial activity in areas you care about, from local forests to global supply chains. For journalists, researchers, and activists, it may dramatically lower the barrier to conducting large-scale investigations that were once only possible for well-funded organizations. The availability of an 'Open' tier means you can start using core features without cost or a waitlist.

What's Next

Earth Index's developers state they intend to keep access free for high-impact users. The tool's advanced capabilities, including higher usage limits and a 'Deep Search' feature, are available through a separate tier. As more people use the tool, it may lead to the discovery of previously unreported environmental and industrial activities worldwide.
