+## Input data
+* Sentinel-2 (Level 1C)  multispectral dataset global coverage
+* All samples from [**MajorTOM Core-S2L1C**](https://huggingface.co/datasets/Major-TOM/Core-S2L1C)
+* Image input size: **224 x 224** pixels, target overlap: 10%, border_shift: True
+
+## Model
+The image encoder of the [**DeCUR model**](https://github.com/zhu-xlab/DeCUR) was used to extract embeddings.
+
+## Example Use
+Interface scripts are available at
+```python
+from datasets import load_dataset
+dataset = load_dataset("Major-TOM/Core-S2L1C-DeCUR")
+```
+## Generate Your Own Major TOM Embeddings
+
+The [**embedder**](https://github.com/ESA-PhiLab/Major-TOM/tree/main/src/embedder) subpackage of Major TOM provides tools for generating embeddings like these ones. You can see an example of this in a dedicated notebook at https://github.com/ESA-PhiLab/Major-TOM/blob/main/05-Generate-Major-TOM-Embeddings.ipynb.

+## Major TOM Global Embeddings Project 🏭
+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.
+
+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.
+
+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 💻☁️.

+  
+  > With the ever-increasing volumes of the Earth observation data present in the archives of large programmes such as Copernicus, there is a growing need for efficient vector representations of the underlying raw data. The approach of extracting feature representations from pretrained deep neural networks is a powerful approach that can provide semantic abstractions of the input data. However, the way this is done for imagery archives containing geospatial data has not yet been defined. In this work, an extension is proposed to an existing community project, Major TOM, focused on the provision and standardization of open and free AI-ready datasets for Earth observation. Furthermore, four global and dense embedding datasets are released openly and for free along with the publication of this manuscript, resulting in the most comprehensive global open dataset of geospatial visual embeddings in terms of covered Earth's surface.
