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:

Source hierarchy

Records are compiled in this order of preference when the same physical ramp appears in multiple datasets:

  1. State agency dataset (DNR, FWC, DEC, DEP, etc.)
  2. Federal agency (USACE, NPS, USFS, BLM, USFWS, USGS)
  3. Google Places (enrichment for addresses, hours, ratings)
  4. 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 sources array; do not strip it.
