- ## Input data
41
- * Sentinel-2 (Level 1C) multispectral dataset global coverage
42
- * All samples from [**MajorTOM Core-S2L1C**](https://huggingface.co/datasets/Major-TOM/Core-S2L1C)
43
- * Image input size: **224 x 224** pixels, target overlap: 10%, border_shift: True
44
-
45
- ## Model
46
- The image encoder of the [**SSL4EO-ResNet50-DINO model**](https://github.com/zhu-xlab/SSL4EO-S12) was used to extract embeddings.
47
-
48
- ## Example Use
49
- Interface scripts are available at
50
- ```python
51
- from datasets import load_dataset
52
- dataset = load_dataset("Major-TOM/Core-S2L1C-SSL4EO")
53
- ```
54
- ## Generate Your Own Embeddings
55
-
56
- The [**embedder**](https://github.com/ESA-PhiLab/Major-TOM/tree/main/src/embedder) subpackage of Major TOM provides tools for generating embeddings like this ones. You can see an example of this in a dedicated notebook at (link).

- ## Major TOM Global Embeddings Project 🏭
61
- This dataset is a result of a collaboration between [**CloudFerro**](https://cloudferro.com/) 🔶 and [**Φ-lab, European Space Agency (ESA)**](https://philab.esa.int/) 🛰️ set up in order to provide open and free vectorised expansions of Major TOM datasets and define a standardised manner for releasing Major TOM embedding expansions.
62
-
63
- The embeddings extracted from common AI models make it possible to browse and navigate large datasets like Major TOM with reduced storage and computational demand.
64
-
65
- The datasets were computed on the [**GPU-accelerated instances**](https://cloudferro.com/ai/ai-computing-services/)⚡ provided by [**CloudFerro**](https://cloudferro.com/) 🔶 on the [**CREODIAS**](https://creodias.eu/) cloud service platform 💻☁️.
