A new research paper explores the use of AlphaEarth foundation embeddings for mapping croplands in Maine, USA. The study found that these embeddings, without fine-tuning, achieved high accuracy in distinguishing cultivated land from non-cultivated areas. The research also demonstrated the temporal transferability of these models, showing that classifiers trained in one year remained effective across several subsequent years. When compared to existing methods like the USDA Cropland Data Layer and a fine-tuned TerraMind model, AlphaEarth embeddings showed competitive or superior performance in accuracy and agreement. AI
