Two habitat maps of the Dark Peak side by side. Left: the map from AlphaEarth embeddings and logistic regression, with large purple blanket bog areas on Kinder Scout and Bleaklow, lilac heath around them, orange bracken on the valley sides, yellow and light green grassland in the south and west, and blue reservoirs in the Derwent valley. Right: Living England 2022-23 for the same area, with very similar patterns.

AlphaEarth satellite embeddings in Python: few-shot habitat mapping, uncertainty and area estimates

Use Google DeepMind's AlphaEarth Foundations satellite embeddings, a geospatial foundation model, in Python without a login. Classify nine Peak District habitats with a linear model, compare a few-shot learning curve against raw Sentinel-2 bands, map uncertainty, check calibration, simulate active learning, and estimate habitat areas with confidence intervals from a stratified random sample (Olofsson et al. 2014).
