## 📦 Installation

```bash
# Install all required packages
pip install -r requirements.txt

# For real image downloading (optional)
pip install pystac-client planetary-computer
```

## 🚀 Quick Start

```python
from data_loader import SatelliteDatasetLoader
from advanced_processing import AdvancedImageProcessor
from ml_integration import SatelliteMLProcessor

# Load data
loader = SatelliteDatasetLoader()
image, labels = loader.load_image_pair("sample_001")

# Advanced processing
processor = AdvancedImageProcessor()
edges = processor.detect_edges(image, method='canny')
features = processor.extract_all_features(image)

# ML processing
ml = SatelliteMLProcessor()
buildings = ml.detect_buildings_simple(image)
ndvi = ml.extract_ndvi(image)
```
