OpenStreetMap data — licence and attribution notice
===================================================

This notice applies to the OpenStreetMap-derived files served from
https://assets.secondkickmoto.com/ — specifically:

    states/{state}/{state}.pmtiles         vector basemap tiles, 50 states
    states/{state}/{state}-roads.pmtiles   low-zoom road network, 50 states
    states/{state}/{state}.pack            routing graphs, 50 states
    nationwide/nationwide-overview.pmtiles

and the copies of the same files, under the same names and terms, in the older
v1/ and v2/ prefixes, every dated vintage ({name}.{YYYYMMDD}.{ext}) included.

Since 2026-10-08 the routing graphs of the fourteen states with Bureau of Land
Management routes are OpenStreetMap merged with BLM's Ground Transportation
Linear Features (a US Government work, public domain): BLM routes missing from
OpenStreetMap are added, and BLM's vehicle designations are attached to the
OpenStreetMap ways they match. The merged files are derivative databases of
OpenStreetMap; they are the files offered here, under the same ODbL terms, and
ATTRIBUTION.md beside this file describes how they are made.

These files contain information from OpenStreetMap, which is made available
under the Open Database License (ODbL) v1.0.

What that means for anyone using these files
--------------------------------------------

The ODbL is a share-alike licence for databases. In short, and without being
legal advice — read the licence itself before relying on any of this:

  * ATTRIBUTE. Any public use of these files, or of a work produced from them,
    must credit "© OpenStreetMap contributors". A visible credit on the map or
    in the about/credits screen of an application is the normal way to do this.

  * SHARE ALIKE. If you publicly use an adapted version of the database, you
    must offer that adapted database under the ODbL as well.

  * KEEP IT OPEN. You may not use technical measures that restrict others from
    using the database as the licence permits.

The tilesets themselves also carry the attribution in their own metadata; a
`pmtiles show --metadata` of any base tileset reports:

    <a href="https://www.openstreetmap.org/copyright" target="_blank">&copy; OpenStreetMap</a>

Files here that are NOT OpenStreetMap-derived
---------------------------------------------

Terrain, contour and public-land tiles come from other sources with different
terms — US federal public-domain data and the AWS Terrain Tiles collection. See
ATTRIBUTION.md beside this file for the per-file-kind breakdown, including the
attribution the terrain data's publisher requires.

Provenance for every individual object — upstream, version, licence — is
recorded per file in the application's own compiled-in digest manifest
(`hosted-digests.json`), and the register of licences with their required
attribution text is `docs/DATA-LICENCES.md` in the application's repository.
