<!-- Provide a longer summary of what this dataset is. -->
**Metadata.parquet File**
This dataset shows the relationship between our embeddings/vectors and Major TOM images for fast linking to other Major TOM datasets.
**Embedding.dat**
This dataset has the vector embeddings calculated by us.
What we did was:
a) to vectorise the entire Major-TOM image data for Europe;
b) used the OPENCLIP_SIGLIP_400M on the Quasara Platform for embedding generation
c) no pre-training, no labelling happened in the preparation of this dataset
## Uses
<!-- Address questions around how the dataset is intended to be used. -->
# MajorTOM-Europe Dataset
The **MajorTOM-Europe dataset** provides embeddings derived from high-resolution satellite images of the Europe region, generated using the OpenCLIP SigLIP model. These embeddings, extracted from images covering a range of geographic coordinates across Germany, provide a powerful tool for various applications.
## Dataset Information
- **Coordinates Info:** The embeddings cover a range of geographic coordinates across the Europe region.
- **Related Dataset:** The MajorTOM-Europe dataset is closely related to the original **S2L2A** dataset.
## Features
The MajorTOM-Europe dataset leverages CLIP's ability to relate textual descriptions to visual data, enabling more intuitive searches and analysis. This allows users to search among images using text-based queries effectively.
## Applications
The MajorTOM-Europe dataset can be utilized for various applications, including:
- **Monitoring Changes in Land Use and Land Cover:**
- Track deforestation
- Observe urban expansion
- Monitor water body dynamics
- **Precision Agriculture:**
- Analyze crop health
- Predict yields
- Plan harvests
- **Climate Research:**
- Study climate patterns
- Monitor changes and impacts on regional and local levels
