Tessera Sample Dataset
This dataset is a small sample of the Tessera dataset developed by the University of Cambridge Earth Observation Group.
This sample is intended for testing workflows, experimentation, and demonstration purposes.
Original Tessera dataset: GitHub Repository
Dataset Overview
TESSERA (Temporal Embeddings of Surface Spectra for Earth Representation and Analysis) encodes spatio-temporal information from Earth observation data into compact embeddings.
This sample dataset provides:
- Global coverage at 0.1° resolution (coarse sample for testing)
- Time-specific embeddings per grid tile (year 2024)
- 128-dimensional vector per pixel, capturing spectral, spatial, and temporal properties
- Grid-based organization, allowing easy selection of spatial subsets
