## Overview 

The **WikiRS** dataset, composed of triplets of images, species list and Wikipedia sentences :
- **91k high-resolution aerial images** (50cm, RGB bands) from the swissIMAGE product 
- crowd-sourced species observations from **2745 different species**,  collected from **GBIF**, geolocated within the footprint of the aerial image.
- **103K different sentences** describing the habitat of the observed species, extracted from the corresponding Wikipedia article.

## Data formats in this repository

### 1. Original raw data
- In `ecowikirs.zip`
- Original data structure used in the codebase and archived on Zenodo
- Intended for full reproducibility

### 2. Hugging Face processed version
- In the `data/` directory
- Automatically loaded via `load_dataset("EPFL-ECEO/EcoWikiRS")`

### HF Features
- id (string): Unique site/sample identifier
- EUNIS (ClassLabel): Habitat class label. Original codes remapped to contiguous indices to handle gaps.
- species_list (list[string]): All species recorded at the site.
- image (Image): PIL image from TIFF file (`swissimage/{id}.tif` in the raw data).
- species_text (json string): Aggregated JSON data per species (from `wiki/{species_name}.json` in the raw data), keyed by binomial_name, including keywords, habitat_section, and random_sentences.

### Notes
EUNIS labels have been remapped in the Hugging Face processed version to contiguous integers. The mapping is the following:
```{0: 14, 1: 15, 2: 16, 3: 21, 4: 23, 5: 24, 6: 25, 7: 26, 8: 31, 9: 32, 10: 40, 11: 41, 12: 43, 13: 44, 14: 45, 15: 47, 16: 48, 17: 49, 18: 50, 19: 52, 20: 53, 21: 54, 22: 55, 23: 56, 24: 57}```
