Satellite Imagery Time Series at 246,144 Global Locations

246,144 locations each sampled at four timestamps across seven modalities including S2L1C, S2L2A, and S1GRD. The dataset is provided by embed2scale and was last updated in March 2026. It is stored in Zarr Zip files for use with webdataset.

Use Cases

• Train self-supervised models on multi-temporal S2L1C and S2L2A imagery to learn general-purpose satellite image representations.
• Analyze land cover changes by correlating LULC labels with time-series data from the four timestamps per location.
• Fuse S1GRD radar data with S2RGB optical imagery for all-weather geospatial analysis across the 246,144 sample points.
• Develop terrain-aware models by incorporating DEM data alongside spectral indices like NDVI for environmental monitoring.

Strengths

• Contains 246,144 distinct geographic locations, providing broad spatial coverage.
• Each location includes data from four separate timestamps, enabling time-series analysis.
• Integrates seven different data modalities, including optical, radar, and derived products like LULC and NDVI.

Limitations

• The specific temporal range for the four timestamps per location is not detailed in the provided input.
• The dataset's structure as Zarr files requires familiarity with specific libraries for efficient access and processing.
• No column-level schema or sample data is provided, making initial exploration more challenging.
