alphaearth_foundations_core

The Google Satellite Embedding dataset provides 64-dimensional geospatial embeddings representing the semantic characteristics of Earth's surface at 10-meter resolution.

Specifications

• Dataset ID: GOOGLE/SATELLITE_EMBEDDING/V1/ANNUAL
• Bands: 64-dimensional float embeddings, named A00 through A63.
• Unit-Vector Guarantee: The bands are pre-normalized unit vectors (values in range [-1, 1]).

See the catalog page for more details: Satellite Embedding V1 (Annual)

Quantization & De-quantization (Under the Hood)

To store global high-dimensional embeddings efficiently, the dataset is internally quantized to 8-bit signed integers.
