This directory contains the satellite image dataset files.

## Directory Structure

```
data/
├── images/ # Satellite image files (PNG, TIFF, GeoTIFF)
├── labels/ # Land cover classification labels (JSON)
├── metadata/ # Geospatial metadata files (JSON)
├── building_detection/ # Building detection annotations (JSON)
└── samples/ # Sample data for testing
```

## File Formats

### Images
- **PNG**: Standard PNG format for visualization
- **TIFF**: High-quality TIFF format
- **GeoTIFF**: TIFF with embedded geospatial metadata

### Labels (JSON)
Land cover classification labels in JSON format:
```json
{
"image_id": "sample_001",
"classes": ["water", "forest", "urban", "agriculture", "barren"],
"regions": [
{
"class": "urban",
"polygon": [[x1, y1], [x2, y2], ...],
"area": 12345.67
}
]
}
```

### Building Detection (JSON)
Building detection annotations:
```json
{
"image_id": "sample_001",
"buildings": [
{
"bbox": [x, y, width, height],
"confidence": 0.95,
"area": 1234.56
}
]
}
```

### Metadata (JSON)
Geospatial metadata:
```json
{
"image_id": "sample_001",
"crs": "EPSG:4326",
"bounds": {
"min_lon": -122.5,
"min_lat": 37.5,
"max_lon": -122.0,
"max_lat": 38.0
},
"resolution": 0.5,
"acquisition_date": "2024-01-15"
}
```

## Usage

Place your satellite images and corresponding annotation files in the appropriate subdirectories. The dataset loader will automatically discover and load them.

For more information, see the main [README.md](../README.md).
