# 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](https://github.com/ucam-eo/tessera)
## 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**
- **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
## Dataset Structure
The dataset is organized as follows:
```text
tessera_sample/
├── train/
│ └── global_0.1_degree_representation/
│ └── 2024/
│ ├── grid_-94.65_40.75/
│ │ └── grid_-94.65_40.75_2024.tiff
│ ├── grid_-94.75_40.75/
│ │ └── grid_-94.75_40.75_2024.tiff
│ └── grid_-94.85_40.75/
│ └── grid_-94.85_40.75_2024.tiff
└── val/
└── global_0.1_degree_representation/
└── 2024/
└── grid_-94.95_40.75/
└── grid_-94.95_40.75_2024.tiff
```
- Each folder corresponds to a **geospatial grid tile**.
- File naming format: `grid_<longitude>_<latitude>_<year>.tiff`.
