Required attribution
Include the following near where the data is displayed, in documentation, or in your app’s about/credits page:
Boat ramp data: BoatLaunchMap (https://boatlaunchmap.com), licensed CC BY 4.0. Individual records also credit the originating state or federal agency in the `sources` field.
For per-record agency credit, surface the contents of each Feature’s sources array — these identify the specific state DNR / FWC / DEC / DEP / USACE record that the datapoint came from.
Schema
Standard GeoJSON FeatureCollection. EachFeature has a Point geometry in WGS84 (EPSG:4326) and these properties:

| state | string | Full state name (e.g. "Florida") |
| zip_code | string | |
| access_type | string | "public" or "private" |
| is_tidal | boolean | True if coastal/tidal water |
| primary_source | string | Canonical attribution code (e.g. ARC:NY:NEW_YORK_DEC_BOAT_LAUNCHES, nc_wrc, OpenStreetMap, GooglePlaces) |
| sources | string[] | All sources that contributed data for this record |
| google_rating | number | Average Google Maps rating, 1–5 (if available) |
| google_review_count | number | Number of Google reviews (if available) |

Source hierarchy
Records are compiled in this order of preference when the same physical ramp appears in multiple datasets:
- State agency dataset (DNR, FWC, DEC, DEP, etc.)
- Federal agency (USACE, NPS, USFS, BLM, USFWS, USGS)
- Google Places (enrichment for addresses, hours, ratings)
- OpenStreetMap (gap-filling where no authoritative source exists)
Full methodology and the per-agency authoritative source list is documented at /methodology.
Use cases & partnerships
Building something that uses this data? We’d love to hear about it. Common integrations:
- Fishing & boating apps overlaying ramps on charts
- Marina and bait-shop sites showing nearby launches
- State or county tourism boards linking to public access
- GIS & outdoor-recreation research
- Marine routing & trip-planning tools

Restrictions
CC BY 4.0 has no field-of-use restrictions, but please:
- Don’t imply BoatLaunchMap endorses your application.
- Don’t scrape detail pages bypassing the GeoJSON endpoint — the bulk endpoint is faster and cheaper for you and our infrastructure.
- For per-record agency credit, surface the
sourcesarray; do not strip it.
