# 🌱 GreenHySpectra: A multi-source hyperspectral dataset for global vegetation trait prediction 🌱

GreenHySpectra is a collection of hyperspectral reflectance data of vegetation from different sources. It is intended for Regression machine learning task for plant trait prediction with self and semi-supervised learning.

## 📁 Configurations
### 1. `GreenHySpectra: Unlabeled Set`
- Files: all CSVs under `unlb/`
- Contains:
  - Sample ID
  - Spectral bands (400-2450 nm) >> 1721 bands

| Column         | Description                             |
|----------------|-----------------------------------------|
