| # 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`. |
