This dataset was developed\nin collaboration with the Oxford Leverhulme Centre for Nature Recovery to\nserve as a baseline for applications including landscape restoration,\nbiodiversity monitoring, and ecological connectivity analysis.\n\nThe dataset was generated by applying a vision transformer model to a mosaic\nof high-resolution aerial imagery, trained using a large corpus of\nhuman-annotated labels. The output consists of three distinct probability\nlayers, one for each feature class. This probabilistic format allows users\nto apply custom thresholds to generate binary feature maps tailored to their\nspecific analytical requirements.\n\n**Limitations**\n\n- Geographic Scope: Model performance is reduced in dense urban environments and montainous areas, which were underrepresented in the training data that focused primarily on rural landscapes.\n- Temporal Accuracy: The source imagery was captured between 2018 and 2020. Consequently, the dataset does not account for landscape changes that have occurred since this period.\n- Class-Specific performance: The stone wall class exhibits lower accuracy compared to woodland and hedgerows, a result of significant class imbalance in the training data.\n\n**Europe Dataset**\n\nIn addition to the primary dataset for England, a preliminary version has\nbeen generated at a European scale. This dataset has not been subjected to\nthe same quantitative validation and should be considered experimental.\nIt is possible to request access to this dataset by submitting\n[this form](https://docs.google.com/forms/d/e/1FAIpQLSfokil1-UFfTxvVhihLx9W3-K51o900VF4ACqkwG1jYmP0W8g/viewform).\n\n### Bands\n\n\n**Pixel Size**\n\n0.25 meters\n\n**Bands**\n\n| Name | Min | Max | Scale | Pixel Size | Description |\n|------|-----|-----|-------|------------|--------------------------------------------------|\n| `B0` | 0 | 250 | 0.004 | meters | Hedgerow probability (scaled to \\[0-250\\]). |\n| `B1` | 0 | 250 | 0.004 | meters | Stone wall probability (scaled to \\[0-250\\]). |\n| `B2` | 0 | 250 | 0.004 | meters | Woodland/tree probability (scaled to \\[0-250\\]). |\n\n### Terms of Use\n\n**Terms of Use**\n\nThis dataset is licensed under\n[CC-BY-NC 4.0](https://creativecommons.org/licenses/by-nc/4.0/) and requires\nthe following attribution: \"This dataset is produced by Google\".\n\n### Citations\n\nCitations:\n\n- Michelangelo Conserva, Alex Wilson, Charlotte Stanton, Vishal Batchu, Varun\n Gulshan , \"Mapping Farmed Landscapes from Remote Sensing\" (in review).\n [doi:10.48550/arXiv.2506.13993](https://doi.org/10.48550/arXiv.2506.13993),\n\n### Explore with Earth Engine\n\n| **Important:** Earth Engine is a platform for petabyte-scale scientific analysis and visualization of geospatial datasets, both for public benefit and for business and government users.
