Google introduces the Planetary Prediction Engine (PPE), an experimental AI capability within Google Earth AI that automates geospatial modeling. PPE handles the full workflow from data discovery to model training, addressing challenges in public health, food security, and environmental risk. It overcomes the bottleneck of fragmented data and manual engineering by using LLM-orchestrated stages: intelligent data selection, multimodal curation, and automated model building.

PPE retrieves covariates from repositories like Data Commons and Google Earth Engine, plus live web discovery. It integrates foundation models like PDFM and Alpha Earth, and applies anti-leakage and overfitting guards. This reduces model development time from weeks to minutes, enabling rapid responses to humanitarian crises.
