How complete the places are.
Boat ramps, marinas, hotels, motels, resorts and parks, from OpenStreetMap, with hotels and marinas checked against Overture Maps. Each one is graded.
- Verified Confirmed by a second source, or carries the details that matter for its kind: operator, phone, address, website, surface or hours.
- Likely Named, with some details.
- Thin Few details. Check before you rely on it.
District by district.
Are the sources up?
Every day an automatic check calls each service LightKeeper uses.
What this measuresCompleteness and freshness, not a promise that every place is right. "Confirmed by a second source" is the share that an official list or another dataset agrees with; it rises as those are added (see the roadmap). Not for navigation.
