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 # 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 ## Dataset Structure **Metadata.parquet** | Column | Explanation | |----------------|-----------------------------------------------------------------------------------------------| | grid_cell | Coordinates in the Major TOM grid, enabling fast linking to other Major TOM datasets. | | grid_row_u | Row identifier in the Major TOM grid for linking purposes. | | grid_row_r | Another row identifier in the Major TOM grid for linking purposes. | | centre_lat | Latitude of the center of the image portion for which embedding has been computed. | | centre_lon | Longitude of the center of the image portion for which embedding has been computed. | | timestamp | Date and time of the original product in the %Y%m%dT%H%M%S format. | | dat_row | Row number in the .dat file associated with the data entry. | | unique_id | Unique identifier combining grid_cell, timestamp, and possibly other parameters (e.g., parquet).| | image_type | Each image is split into 70 segments and vectorized. | | coordinates | Coordinates in the image that define the segment that was vectorized.
