# Data sources — coverage audit (2026-07-20)

## Decision: **GO** for Tyrol + Salzburg beta

Österreich Werbung open data alone provides dense, contactable inventory. OSM supplements nearby trails/lifts and fill gaps. Published prices are rare — UI must default to “Preis auf Anfrage”.

| Feed | Endpoint (ObjectType) | National count | Tyrol+Salzburg |
|------|----------------------|----------------|----------------|
| Accommodations | `Vermieter` | 43,517 | **26,035** (Tirol 17,728 / Salzburg 8,307) |
| POIs | `POI` | 89,538 | ~19,156 |
| Tours | `Tour` | download truncated once during audit — treat as optional |

### Vermieter fill rates (Tyrol + Salzburg)

| Field | Coverage |
|-------|----------|
| Coordinates | 94.5% |

## OpenStreetMap (ODbL)

Use cached Overpass / Geofabrik extracts for:

- Additional accommodations (gap fill)
- Hiking paths, MTB routes, aerialways / ski lifts
- Amenity proximity signals

Never query Overpass on the guest request path. Public Overpass was busy during audit; importer must tolerate failures and keep last-good snapshots.

## GTFS

Deferred to post-v1.

## Go / no-go criteria

| Criterion | Result |
|-----------|--------|
| Contactable density | Pass (email/phone high) |
| Geo coverage | Pass |
| Sports/wellness signals | Pass (features + POIs) |
| Licensed images | Pass with filter |
| Live / published prices | Fail — expect sparse; do not rank by price |

**Proceed** with importer + thin discovery UX. Do not block on prices or Tour feed.
