Google's AlphaEarth Foundations: A Leap Forward in Environmental Monitoring
Google's EarthAI initiative has launched a new AI model, AlphaEarth Foundations, designed for global environmental monitoring. This groundbreaking tool is set to revolutionise the fields of water management, climate resilience, and environmental monitoring, among others.
The merger of AlphaEarth Foundations and Gemini, a general reasoning AI, is expected to further improve environmental monitoring, food security, water management, and urban planning. The model utilises large-scale Earth observation datasets to improve the mapping of terrestrial and coastal ecosystems with exceptional precision.
AlphaEarth Foundations divides the Earth into 10x10-meter blocks, creating compact, high-fidelity data summaries called embeddings. These embeddings enable faster, more accurate mapping and better classification of unmapped ecosystems. Over 50 institutions, including the UN Food and Agriculture Organization, Stanford University, and Harvard Forest, have tested AlphaEarth Foundations for various uses, such as ecosystem classification and deforestation alerts.
The geospatial AI model analyses petabytes of multimodal data, including optical and radar satellite imagery, 3D LiDAR, and climate simulation data. This analysis results in a 24% reduced error rate compared to previous models, even when only small amounts of training data are available. Tasso Azevedo, founder of Brazil's MapBiomas, states that the tool enables "faster, more accurate" mapping.
In practice, AlphaEarth Foundations is already supporting over 50 partners, including the UN FAO and MapBiomas, by improving mapping speed and accuracy, better classification of unmapped ecosystems, and enhanced tracking of agricultural and environmental changes. Its AI-powered insights aid in flood forecasting, wildfire detection, and detailed weather prediction, contributing directly to climate resilience strategies and disaster preparedness.
Projected future developments include integration with more general reasoning AI models (e.g., Google's Gem) to deepen the interpretative capabilities of the system, enabling even smarter, multi-dimensional Earth analyses. Google’s Earth AI initiative plans expanding these geospatial AI applications further into urban planning, public health, and clean-energy project site identification, leveraging detailed environmental data to inform decision-making in these critical areas.
The combined system is expected to have a reduced error rate in its predictions and analyses. James Cook University's Global Ecosystems Atlas uses AlphaEarth Foundations to identify previously unmapped ecosystems, while Nick Murray, project lead of James Cook University's Global Ecosystems Atlas, calls AlphaEarth Foundations "revolutionary for conservation planning."
AlphaEarth Foundations was officially launched on July 30, 2025, and functions as a virtual satellite. The model has 16x lower storage requirements than alternative systems, making it a practical solution for environmental monitoring on a global scale. Sarah Tancredi, an experienced journalist and news reporter specialising in environmental and climate crisis issues, highlights the importance of this initiative, stating that it represents a significant step forward in leveraging AI to unify diverse Earth observation data, making it a powerful tool for water management, climate resilience, and environmental monitoring now and in the future.
Accessible via Google Earth Engine through the Satellite Embedding dataset, AlphaEarth Foundations is already making a difference in the world of environmental monitoring and conservation. As the system continues to develop and expand, its impact is expected to grow, providing valuable insights for researchers, policymakers, and the public alike.
