## Search Patterns for Thermal Drones
### Expanding Square Search
Best for locating a stationary target:
1. Start at center or last known position
2. Fly outward in expanding squares
3. Adjust altitude based on terrain
4. Overlap coverage for complete search
### Parallel Track Search
Ideal for large areas:
1. Set parallel tracks based on thermal camera FOV
2. Maintain consistent altitude
3. Use 50% overlap between tracks
4. Adjust based on terrain
### Creeping Line Search
Best for linear features:
1. Fly parallel to feature (road, river, ridge)
2. Track one direction, then step and return
3. Good for missing persons near linear features
### Hover and Scan
For precise target location:
1. Hover at key positions
2. Pan camera 360° for complete coverage
3. Methodical grid pattern
4. Useful for small search areas
## Integration with Search Operations
