GEO-INFER-PLACE
Instructions
Core Capabilities
- Place identification: Named place resolution and geocoding
- Catchment analysis: Service area and accessibility modeling
- H3 place-shedding: Hexagonal tessellation of administrative boundaries
- Boundary operations: County/region geometry loading and manipulation
- Unified backend: Multi-source geographic data integration
Key Imports
from geo_infer_place.core.unified_backend import UnifiedPlaceBackend
from geo_infer_place.core.catchment import CatchmentAnalyzer
from geo_infer_place.core.geocoding import PlaceGeocoder
Examples
```python
from geo_infer_place.core.unified_backend import UnifiedPlaceBackend
backend = UnifiedPlaceBackend()
place = backend.resolve("Portland, OR")
print(f"Resolved: {place.name}, Center: ({place.lat}, {place.lng})")
boundary = backend.get_boundary(place.id)
print(f"Boundary: {boundary.area_km2:.1f} km²")
```python
from geo_infer_place.core.catchment import CatchmentAnalyzer
analyzer = CatchmentAnalyzer(mode="drive_time")
catchment = analyzer.compute(
facility_location=(45.5, -122.6),
max_time_minutes=15
)
print(f"15-min catchment: {catchment.area_km2:.1f} km²")
print(f"Population covered: {catchment.population:,}")
Guidelines
- Uses H3 v4 API exclusively
- Fallback synthetic geometries are used when county data is unavailable
- Test:
uv run python -m pytest GEO-INFER-PLACE/tests/ -v
Integrations
- SPACE → H3 tessellation of place boundaries
- DATA → Boundary geometry data sources
- CIV → Community place identification
- HEALTH → Health district boundary resolution
- TRANSPORT → Accessible catchment areas
