rslearn.data_sources.google_earth_engine.GoogleSatelliteEmbeddings

This data source is for Google Satellite Embeddings (AlphaEarth Embeddings) from Google Earth Engine. The embedding values are stored as unsigned 16-bit integers from 0 to 16383, computed by multiplying the original [-1, 1] floating point values by 8192 and adding 8192.
