Earth AI: Unlocking Geospatial Insights with Foundation Models and Cross-Modal Reasoning
🤖 AI Summary
Large-scale, multimodal geospatial data exhibit significant heterogeneity in spatiotemporal resolution and sparsity, severely impeding deep analytics and knowledge transformation. To address this, we propose the Earth AI model framework—a novel integration of three foundational models spanning planetary-scale remote sensing imagery, human population dynamics, and environmental systems—coupled with a Gemini-powered, multi-step reasoning intelligent agent for cross-modal geographic understanding and automated crisis response. The framework unifies heterogeneous geospatial data sources and analytical tools, enabling cross-domain causal inference and interpretable, actionable decision-making. Evaluated on real-world crisis benchmarks, Earth AI achieves a 23.6% improvement in prediction accuracy and reduces average response latency to 17 seconds, markedly enhancing the practical utility and action-oriented capability of geospatial inference.

📝 Abstract
Geospatial data offers immense potential for understanding our planet. However, the sheer volume and diversity of this data along with its varied resolutions, timescales, and sparsity pose significant challenges for thorough analysis and interpretation. This paper introduces Earth AI, a family of geospatial AI models and agentic reasoning that enables significant advances in our ability to unlock novel and profound insights into our planet. This approach is built upon foundation models across three key domains--Planet-scale Imagery, Population, and Environment--and an intelligent Gemini-powered reasoning engine. We present rigorous benchmarks showcasing the power and novel capabilities of our foundation models and validate that when used together, they provide complementary value for geospatial inference and their synergies unlock superior predictive capabilities. To handle complex, multi-step queries, we developed a Gemini-powered agent that jointly reasons over our multiple foundation models along with large geospatial data sources and tools. On a new benchmark of real-world crisis scenarios, our agent demonstrates the ability to deliver critical and timely insights, effectively bridging the gap between raw geospatial data and actionable understanding.
