Sources

Each trail's record (<id>/trail.toml) names its source, the page to ask for the line, and the terms that apply. This file collects the distinct terms, the sentence that states them, the page they were read on, and the date read. Dates read: records were first read on 2026-11-08; the licence pages below were read again on 2026-11-09; 40 designated records and 34 person-defined routes were added and read on 2026-11-10.

A line is included in this repository only when its source's terms allow redistribution. Where they do not, the trail is a record only and source.line_absent_reason in its record says why.

OpenStreetMap (ODbL-1.0)

Used by: 77 trails with an included line, and part of the Colorado Trail line (about 38 km; the rest is United States Forest Service data). Also named as the recorded source for 8 record-only trails, where no line was downloaded or none was usable. One of the person-defined routes has a line from OpenStreetMap (the Big SEKI Loop, relation 11628437); the other 33 name no source licence for a line.

Quoted terms: "You are free to copy, distribute, transmit and adapt our data, as long as you credit OpenStreetMap and its contributors."

United States federal agencies (public domain)

Publishers: National Park Service, USDA Forest Service and Bureau of Land Management services named in each record. Used by: 6 trails with an included line (Appalachian, Colorado Trail in part, Natchez Trace, New England, Pacific Northwest, Potomac Heritage), and named in 4 record-only records (Iditarod, Nez Perce, Overmountain Victory, Timberline).

Quoted terms: "Data and content created by government employees within the scope of their employment are not subject to domestic copyright protection under 17 U.S.C. 105."

Page: https://irma.nps.gov/DataStore/Reference/Profile/2311077 (read 2026-11-09). United States federal government work is public domain in the United States under 17 U.S.C. 105. Two included lines were produced with partner associations (Appalachian and New England); the partners' share is not separately licensed in those services, and is noted in the records.

Pacific Crest Trail Association (CC-BY-4.0)

Used by: 1 trail (Pacific Crest).

Quoted terms: "All of the data accessed through this page are licensed under the Creative Commons Attribution 4.0 International License."

Page: https://www.pcta.org/discover-the-trail/maps/pct-data/ (read 2026-11-09). Full text: LICENSES/CC-BY-4.0.txt. Credit required: Pacific Crest Trail Association.

Continental Divide Trail Coalition (CC-BY, version not stated)

Used by: 1 trail (Continental Divide).

Quoted terms: the source item's licence field reads "CC BY" (no version stated).

Page: https://services8.arcgis.com/WyuHwdftppQLa5KO/arcgis/rest/services/Continental_Divide_Trail_2/FeatureServer/0 (read 2026-11-09). Treated here as Creative Commons Attribution, with credit to the Continental Divide Trail Coalition. The version should be confirmed with the Coalition before a use that needs a named version.

Publishers with no stated licence (no line included)

Used by: 2 records, none with an included line: California Coastal Commission with the Coastal Trails Alliance; Arizona State Parks (Great Western, Arizona part only).

Terms found: no licence stated on the items, and no licence found on the publishers' pages when read on 2026-11-09. The items carry disclaimers only. A disclaimer is not a licence, so these publishers' lines are not redistributed here. Each record's source.url is the page to ask for the line, and source.line_absent_reason states this reason. Nine more records that were listed here had a line added from OpenStreetMap on 2026-11-09; their publishers' own lines are still not used, and each record keeps the publisher and its page in source.publisher and source.publisher_url.

Trans Canada Trail (CC-BY-NC-ND-4.0)

Used by: 1 record (The Great Trail), record only.

Terms: Creative Commons Attribution-NonCommercial-NoDerivatives 4.0, as stated on the source item (read 2026-11-09; source page in the record). Those terms do not allow commercial use or derivatives, so no line from this source is included.

Person-defined routes (creator's own pages, no line included)

Used by: the person-defined routes (kind = "route"). Each record names its creator and the guide the route is got from, in its [[guide]] tables, and route.line_policy says whether the creator shares the line.

Terms found: none. No route creator's page read on 2026-11-10 states a licence for the route's line. The record says where the line may be got from the creator, and source.line_absent_reason says why no line is included here: the route is sold as a guide, the creator withholds the line, the question is not settled, or the creator offers a download with no licence that allows passing it on. Where OpenStreetMap carries the route as a route relation and the creator publishes the line freely, the line comes from OpenStreetMap under the terms above.

Page: the creator's or publisher's own page for the guide, given in each record's first [[guide]] and quoted in route.creator_words_url where the creator's words are quoted.
