No authbts-ntad

US transportation infrastructure — National Transportation Atlas Database. No auth. - searchRailLines (~302K) ⭐ Class I owners (BNSF/UP/CSXT/NS/CN/CPKC), passenger flag - searchPorts (175) ⭐ vessel calls + gross tonnage by coast region - searchLocksAndDams (~196 lock-bearing default; ~92K all dams) ⭐ NID - searchAirports (~19.4K FAA) airports/heliports/seaplane bases - searchIntermodalTerminals (pipeline 1.4K / liquid bulk 640 / rail TOFC 241 / RoRo 84) - getServiceInfo upstream quirks: dams layer uses full state names not codes; pipeline terminals use Y/N/NA on CRUDE_OIL/REFINED; liquid bulk uses 'Y' and most attribute columns are sparse; rail uses 3-digit CNTYFIPS suffix without state prefix.

Methods (6)

  • searchRailLines

    read

    North American rail network. Filters: owner, state, county FIPS, bbox, passenger.

    owner is RROWNER1 code (BNSF/UP/CSXT/NS/CN/CPKC). Use bbox + state for slicing.

  • searchPorts

    read

    DIPT principal ports — vessel calls + tonnage by state, coast region, bbox.

    coastRegion: Atlantic, Gulf, Pacific, Great Lakes, Inland. Sorted by tonnage.

  • searchLocksAndDams

    read

    NID dams. Default returns lock-bearing subset. Filters: state, bbox, owner type.

    State accepts code or full name. Pass withLocksOnly=false for all ~92K dams.

  • searchAirports

    read

    FAA aviation facilities. Filters: state, county, siteType, facilityUse, status, arptId.

    siteType: A=Airport, H=Heliport, C=Seaplane, U=Ultralight, G=Glider, B=Balloon.

  • searchIntermodalTerminals

    read

    Pipeline / liquid-bulk / rail-TOFC-COFC / marine-RoRo terminals. Pass terminalType.

    crudeOnly + refinedOnly apply only to terminalType=pipeline (Y/N/NA values).

  • getServiceInfo

    read

    Schema + record counts for the 8 curated services. Pass service to scope.
