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.
