## 📖 Overview
**PrediTree** is a large-scale **multi-temporal, multi-spectral canopy height dataset** designed for 🌍 **remote sensing, forestry monitoring, and environmental analysis**.  
All imagery and canopy height products are **spatially aligned** at **0.5 m resolution**, enabling fine-grained tree growth prediction and ecological studies.

---

## ✨ Key Highlights
- 📊 **Multi-Temporal**: 3 yearly acquisitions (RGB + NIR + NDVI)  
- 🌈 **Multi-Spectral**: High-resolution optical imagery including RGB, NIR, and derived NDVI  
- 🌲 **Canopy Height Models (CHM)**: LiDAR-based data  
- 📏 **Resolution**: 0.5 m 
- 🌍 **Coverage**: France-wide dataset with departmental splits  
- 📦 **Scale**: 785k training patches, ~880 GB of data

| `chm` | 🌲 Canopy Height Model (m) |
| `rgbnir_ndvi_[1-3]` | 📸 RGB + NIR + NDVI imagery for three years (5 bands, 256×256) |
| `rgbnir_year_[1-3]` | 📅 Acquisition year for imagery |
| `chm_mean_year` | 🏞️ Average canopy height across years |
| `no_data_percentage` | ❌ % missing pixels |
| `crs`, `transform`, `bounds`, `resolution` | 🗺️ Geospatial metadata |
