## POI Feature Integration
### How POI Features Improve Predictions
The Forecasting Service uses location-based POI features to enhance prediction accuracy:
**POI Feature Usage:**
```python
from app.services.poi_feature_service import POIFeatureService
# Initialize POI service
poi_service = POIFeatureService(external_service_url)
# Fetch POI features for tenant
poi_features = await poi_service.fetch_poi_features(tenant_id)
# POI features used in predictions:
# - school_density → Higher breakfast demand on school days
# - office_density → Lunchtime demand spike in business areas
# - transport_hub_proximity → Morning/evening commuter demand
# - competitor_proximity → Market share adjustments
# - residential_density → Weekend and evening demand patterns
# - And 13+ more features
```
**Impact on Predictions:**
- **Location-Aware Forecasts** - Predictions account for bakery's specific location context
- **Consistent Features** - Same POI features used in training and prediction ensure consistency
- **Competitive Intelligence** - Adjust forecasts based on nearby competitor density
- **Customer Segmentation** - Different demand patterns for residential vs commercial areas
- **Accuracy Improvement** - POI features contribute 5-10% accuracy improvement
**Endpoint Used:**
- `GET {EXTERNAL_SERVICE_URL}/poi-context/{tenant_id}` - Fetch POI features
## Integration Points
### Dependencies (Services Called)
- **Sales Service** - Fetch historical sales data for training
- **External Service** - Fetch weather, traffic, and holiday data
- **External Service** - Fetch weather, traffic, holiday, and POI feature data
- **Training Service** - Load trained Prophet models
- **Redis** - Cache predictions and session data
- **PostgreSQL** - Store forecasts and performance metrics
