Google DeepMind’s AlphaEarth: Mapping Earth with Unmatched Precision

Published Date : 6/9/2025 

Google DeepMind has introduced AlphaEarth Foundations, a groundbreaking AI model that merges satellite images and environmental data to create a consistent and detailed view of Earth. This model helps scientists and governments make better decisions about land and sea management. 

Google DeepMind has introduced a new artificial intelligence model called AlphaEarth Foundations, which captures vivid details of the Earth’s surface. This model helps scientists and governments make better decisions about the land and sea. According to a blog post, AlphaEarth Foundations pulls together satellite images and other environmental data to create a single, comprehensive picture of the planet.

Satellites orbiting Earth collect vast amounts of information daily. While this data is valuable, it often comes in many different formats and from various times and sensors, making it difficult to combine. AlphaEarth Foundations acts like a virtual satellite, merging all this information into one consistent view.

For example, the model can see through persistent clouds in Ecuador to map agricultural plots in various stages of development. It can also map the surface of Antarctica, which is usually a tough place to image. The AI model can spot changes in land use, such as new construction, deforestation, or crop growth, in 10-meter squares. It also stores information much more efficiently, using 16 times less space than comparable AI systems.

To make the model available to the public, Google is releasing yearly snapshots from 2017 through 2024 in a new Satellite Embedding dataset within Google Earth Engine. This dataset contains more than 1.4 trillion data points each year and is ready to use without extra processing work. Over 50 organizations have already tested the system, including the United Nations’ Food and Agriculture Organization, Stanford University, Oregon State University, and others.

The Global Ecosystems Atlas, an initiative that aims to comprehensively map and monitor the world’s ecosystems, is using AlphaEarth Foundations to help countries classify unmapped ecosystems into categories such as coastal shrublands. In Brazil, the environmental mapping group MapBiomas is using the tool to track farmland and forest changes.

However, even though the model is a cutting-edge technological breakthrough in Earth mapping, it is dependent on high-quality satellite data. According to a GoGeomatics Canada blog post, while the model is known for effectively filling gaps in missing or incomplete data, interpreting poor-quality inputs in critical situations can lead to misdirection.

AlphaEarth Foundations combines information from many different satellite and environmental sources into one clear, consistent picture of Earth. It works a bit like stitching together thousands of puzzle pieces into a single image, except the puzzle pieces come from different satellites, sensors, and even time periods. The system takes in a variety of public data, including optical satellite photos, radar scans that can penetrate cloud cover, 3D laser mapping, climate and environmental readings, elevation maps, gravity measurements, and descriptive information linked to locations.

It treats the images from the same location over time like frames in a video, allowing it to understand changes through the seasons or from one year to the next, such as crops being planted and harvested, forests being cleared, or cities expanding. AlphaEarth Foundations then condenses all this into a 64-dimensional representation for each 10-meter square, whether land or coastal water. This 64-dimensional representation provides richer detail, not just location but also appearance, environment, and behavior over time.

Christopher Seeger, professor and extension specialist of landscape architecture and geospatial technology at Iowa State University, told The Register, 'What is interesting is that they’re able to get down to 10-by-10 meter squares, which is phenomenal. It’s going to be great for decision makers.' This breakthrough enables scientists to create detailed, consistent maps of our world on demand, no longer having to rely on a single satellite passing overhead. They now have a new kind of foundation for geospatial data.
