Description: Fits species distribution models and maps habitat
        suitability at up to 10 m resolution from occurrence records
        alone, using the 'AlphaEarth' Foundations satellite embeddings
        (Brown et al. 2025) <doi:10.48550/arXiv.2507.22291>. The
        embeddings, 64 values per pixel per year from a geospatial
        foundation model, replace environmental layers, so none need to
        be sourced or aligned. Provides tools to format occurrence
        records, place pseudo-absences, train and evaluate an ensemble
        of machine learning models, and export habitat-suitability
        rasters. Sampling, model training and prediction all run on
        'Google Earth Engine', which requires a free account for
        noncommercial use.
