How the ramp directory is assembled

Boat Ramp Scout is a best-effort compilation of public recreation records and mapped launch points. It is designed for discovery and trip planning—not as an authoritative notice of current operating conditions.

1. Source discovery

We prioritize official state and federal inventories, then use national recreation data and community mapping to improve reach. Source pages are audited, and every published row retains a source name, URL, category, retrieval date, and licensing note. Approximately 94% of primary listing records currently come from state or federal sources.

2. Ramp filtering

Agency datasets often mix boat ramps with fishing access, campgrounds, marinas, and other recreation assets. Records are kept when source attributes or descriptions indicate an actual ramp, launch, slipway, hand launch, or recreation facility with a boat ramp. Negative descriptions such as “no boat ramp” are excluded when they can be detected reliably.

3. Normalization and geography

Fields from different agencies are mapped into a consistent schema. Coordinates are validated, and state and county geography is assigned against U.S. Census cartographic boundaries. Values such as yes/no flags, source dates, fees, lane counts, and amenity fields are normalized without converting missing data into a positive claim.

4. Deduplication

Records close to one another are compared by distance, name similarity, and source category. Likely duplicates are merged into one listing, with the higher-quality record serving as the primary row and alternate sources preserved.

5. Enrichment

Each listing receives a stable public slug, a direct directions link, a source-grounded description, customer-facing decision signals, a completeness score, a confidence tier, and an explicit list of verification gaps. Descriptions are generated from known row values; they do not claim an amenity that the source does not report.

Important limitations

• Open datasets are not complete and may be stale.
• Water level, weather, construction, closures, and fees can change daily.
• A mapped launch point is not proof that every boat or trailer can use it.
• “Not reported” is different from “not available.”
• Community-submitted corrections are reviewed before publication.
