These terms cover your use of Contourline (contourline.shop). By reading and using the site, you agree to them. If you don't agree, the simplest remedy is to stop using the site.
Contourline is an independent editorial journal about amateur cartography and map reading. It is written for general interest and education. Nothing on this site is a substitute for a certified survey, an official topographic map from a national mapping agency, or professional navigation training, and nothing here should be relied on for safety-critical route planning.
Unless otherwise noted, the text, illustrations, and design on Contourline are original work and belong to the site. You're welcome to read, link to, and quote short excerpts with attribution. Reproducing whole articles elsewhere without permission isn't allowed.
We try to be careful, and our content policy (see About) commits us to logging corrections openly. Even so, cartography has a long history of estimates and approximations, and some figures on this site are necessarily generalizations rather than exact measurements. Use your judgment, and don't treat anything here as an authoritative survey record.
Waypoint Card, described on our app page, is offered as a reference companion, not as a certified navigation instrument. It is not a substitute for a map, compass, or professional navigation equipment, and should not be relied on as your sole means of route-finding.
You agree not to misuse the site — for example, by attempting to disrupt it, scrape it at a disruptive rate, or use it to distribute anything unlawful.
Some articles link to outside sources. We don't control those sites and aren't responsible for their content or availability.
Contourline is provided "as is," without warranties of any kind, express or implied, including as to accuracy, completeness, or fitness for a particular purpose.
To the extent permitted by law, Contourline and its writers aren't liable for any loss or damage arising from your use of, or reliance on, the site's content.
We may update these terms from time to time. Continued use of the site after a change means you accept the updated terms.
