Credits

Last updated: 25 September 2026

Our maps are built on open data and openly licensed code that other people chose to share. Here is whose work it is, and the licence each part comes under.

Maps

The map style, SightQuests Topo, is our own. What it draws comes from these projects.

OpenStreetMap

Roads, rivers, fells and place names: nearly everything on our maps. Map data © OpenStreetMap contributors, available under the Open Database License.

OpenMapTiles

The vector tile schema: how OpenStreetMap data is cut into the layers our style draws. © OpenMapTiles. The schema's design is licensed under CC BY 4.0, its code under the BSD 3-Clause licence.

OpenFreeMap

Serves the vector tiles for every map, free and without an API key. The credit on the maps doesn't have to name it, so we thank it here.

CARTO

Draws the simpler fallback map for browsers without WebGL2, or when our own map can't load. © OpenStreetMap contributors © CARTO.

Elevation

Hike maps, and Explore with Relief switched on, show contour lines and hill shading.

Mapterhorn

Terrain tiles that join open elevation models from around the world into one. We compute the contour lines and the hill shading from them ourselves, so what you see is our work on their data. Mapterhorn lists every source it uses; these are the ones behind the places we cover.

Finland
Contains data from the National Land Survey of Finland Elevation model 2 m, delivered 2025. CC BY 4.0.
Norway
©Kartverket, Terrengmodellar (DTM). CC BY 4.0.
Sweden
Lantmäteriet, Markhöjdmodell Nedladdning. Released under CC0, so no credit is required. We give it anyway.
Elsewhere

Where the relief comes from Copernicus GLO-30, the global model that fills the gaps between national ones, it is “produced using Copernicus WorldDEM-30 © DLR e.V. 2010-2014 and © Airbus Defence and Space GmbH 2014-2018 provided under COPERNICUS by the European Union and ESA; all rights reserved”.

The organisations in charge of the Copernicus programme by law or by delegation do not incur any liability for any use of the Copernicus WorldDEM-30.

Software

The code that draws our maps is openly licensed. Those licences ask us to pass their notices on, and our production build strips them from the code, so here they are: each library's own, and those of the packages built into MapLibre GL JS.

React LeafletHippocratic License 2.1

Connects Leaflet to React, which the site is built with.

Licence text: react-leaflet
react-leaflet Copyright 2020 Paul Le Cam and contributors (“Licensor”)

Hippocratic License Version Number: 2.1.

Purpose. The purpose of this License is for the Licensor named above to permit the Licensee (as defined below) broad permission, if consistent with Human Rights Laws and Human Rights Principles (as each is defined below), to use and work with the Software (as defined below) within the full scope of Licensor’s copyright and patent rights, if any, in the Software, while ensuring attribution and protecting the Licensor from liability.

Permission and Conditions. The Licensor grants permission by this license (“License”), free of charge, to the extent of Licensor’s rights under applicable copyright and patent law, to any person or entity (the “Licensee”) obtaining a copy of this software and associated documentation files (the “Software”), to do everything with the Software that would otherwise infringe (i) the Licensor’s copyright in the Software or (ii) any patent claims to the Software that the Licensor can license or becomes able to license, subject to all of the following terms and conditions:

- Acceptance. This License is automatically offered to every person and entity subject to its terms and conditions. Licensee accepts this License and agrees to its terms and conditions by taking any action with the Software that, absent this License, would infringe any intellectual property right held by Licensor.

- Notice. Licensee must ensure that everyone who gets a copy of any part of this Software from Licensee, with or without changes, also receives the License and the above copyright notice (and if included by the Licensor, patent, trademark and attribution notice). Licensee must cause any modified versions of the Software to carry prominent notices stating that Licensee changed the Software. For clarity, although Licensee is free to create modifications of the Software and distribute only the modified portion created by Licensee with additional or different terms, the portion of the Software not modified must be distributed pursuant to this License. If anyone notifies Licensee in writing that Licensee has not complied with this Notice section, Licensee can keep this License by taking all practical steps to comply within 30 days after the notice. If Licensee does not do so, Licensee’s License (and all rights licensed hereunder) shall end immediately.

- Compliance with Human Rights Principles and Human Rights Laws.

  1. Human Rights Principles.

     (a) Licensee is advised to consult the articles of the United Nations Universal Declaration of Human Rights and the United Nations Global Compact that define recognized principles of international human rights (the “Human Rights Principles”). Licensee shall use the Software in a manner consistent with Human Rights Principles.

     (b) Unless the Licensor and Licensee agree otherwise, any dispute, controversy, or claim arising out of or relating to (i) Section 1(a) regarding Human Rights Principles, including the breach of Section 1(a), termination of this License for breach of the Human Rights Principles, or invalidity of Section 1(a) or (ii) a determination of whether any Law is consistent or in conflict with Human Rights Principles pursuant to Section 2, below, shall be settled by arbitration in accordance with the Hague Rules on Business and Human Rights Arbitration (the “Rules”); provided, however, that Licensee may elect not to participate in such arbitration, in which event this License (and all rights licensed hereunder) shall end immediately. The number of arbitrators shall be one unless the Rules require otherwise.

     Unless both the Licensor and Licensee agree to the contrary: (1) All documents and information concerning the arbitration shall be public and may be disclosed by any party; (2) The repository referred to under Article 43 of the Rules shall make available to the public in a timely manner all documents concerning the arbitration which are communicated to it, including all submissions of the parties, all evidence admitted into the record of the proceedings, all transcripts or other recordings of hearings and all orders, decisions and awards of the arbitral tribunal, subject only to the arbitral tribunal's powers to take such measures as may be necessary to safeguard the integrity of the arbitral process pursuant to Articles 18, 33, 41 and 42 of the Rules; and (3) Article 26(6) of the Rules shall not apply.

  2. Human Rights Laws. The Software shall not be used by any person or entity for any systems, activities, or other uses that violate any Human Rights Laws. “Human Rights Laws” means any applicable laws, regulations, or rules (collectively, “Laws”) that protect human, civil, labor, privacy, political, environmental, security, economic, due process, or similar rights; provided, however, that such Laws are consistent and not in conflict with Human Rights Principles (a dispute over the consistency or a conflict between Laws and Human Rights Principles shall be determined by arbitration as stated above). Where the Human Rights Laws of more than one jurisdiction are applicable or in conflict with respect to the use of the Software, the Human Rights Laws that are most protective of the individuals or groups harmed shall apply.

  3. Indemnity. Licensee shall hold harmless and indemnify Licensor (and any other contributor) against all losses, damages, liabilities, deficiencies, claims, actions, judgments, settlements, interest, awards, penalties, fines, costs, or expenses of whatever kind, including Licensor’s reasonable attorneys’ fees, arising out of or relating to Licensee’s use of the Software in violation of Human Rights Laws or Human Rights Principles.

- Failure to Comply. Any failure of Licensee to act according to the terms and conditions of this License is both a breach of the License and an infringement of the intellectual property rights of the Licensor (subject to exceptions under Laws, e.g., fair use). In the event of a breach or infringement, the terms and conditions of this License may be enforced by Licensor under the Laws of any jurisdiction to which Licensee is subject. Licensee also agrees that the Licensor may enforce the terms and conditions of this License against Licensee through specific performance (or similar remedy under Laws) to the extent permitted by Laws. For clarity, except in the event of a breach of this License, infringement, or as otherwise stated in this License, Licensor may not terminate this License with Licensee.

- Enforceability and Interpretation. If any term or provision of this License is determined to be invalid, illegal, or unenforceable by a court of competent jurisdiction, then such invalidity, illegality, or unenforceability shall not affect any other term or provision of this License or invalidate or render unenforceable such term or provision in any other jurisdiction; provided, however, subject to a court modification pursuant to the immediately following sentence, if any term or provision of this License pertaining to Human Rights Laws or Human Rights Principles is deemed invalid, illegal, or unenforceable against Licensee by a court of competent jurisdiction, all rights in the Software granted to Licensee shall be deemed null and void as between Licensor and Licensee. Upon a determination that any term or provision is invalid, illegal, or unenforceable, to the extent permitted by Laws, the court may modify this License to affect the original purpose that the Software be used in compliance with Human Rights Principles and Human Rights Laws as closely as possible. The language in this License shall be interpreted as to its fair meaning and not strictly for or against any party.

- Disclaimer. TO THE FULL EXTENT ALLOWED BY LAW, THIS SOFTWARE COMES “AS IS,” WITHOUT ANY WARRANTY, EXPRESS OR IMPLIED, AND LICENSOR AND ANY OTHER CONTRIBUTOR SHALL NOT BE LIABLE TO ANYONE FOR ANY DAMAGES OR OTHER LIABILITY ARISING FROM, OUT OF, OR IN CONNECTION WITH THE SOFTWARE OR THIS LICENSE, UNDER ANY KIND OF LEGAL CLAIM.

This Hippocratic License is an Ethical Source license (https://ethicalsource.dev) and is offered for use by licensors and licensees at their own risk, on an “AS IS” basis, and with no warranties express or implied, to the maximum extent permitted by Laws.
