OpenHikingMap
This is the official OpenHikingMap (OHM) map documentation page, a Free Software mapnik 3+ style based on data from the OpenStreetMap project, I (sly) am working on, specifically designed for hikers. It features contour lines, hiking paths, mountain tracks, natural reserves, moutain huts, peaks, viewpoint, springs and so on... (See full list of rendered features further down)
There is a freely accessible raster TMS service using this style, please check the about page of the OpenMaps service for more information.

History
The first usable version was online around november 2008 but developpement of the style has almost stalled between 2013 and 2018. But in 2020 I have a new hope for improvement by incorporating OpenTopoMap additions. In 2024 and 2025 I mainly cleaned the xml code without significant improvements. But despite a tons of ideas I have, I'm still missing a strong enough server, some help ! or free time to improve the update frequency, the display of moutain ranges, peaks prominence and so on...
Can it be used freely in another website/application ?
It was meant for that. However, there are no guarantees : the service might stop any time, or I might block IP or web site if there are too much requests. If you include tiles from tile.openmaps.fr in your project, you must accept and respect the Tile usage policy where you will also find the TMS URL.
Questions/Suggestions/bug reports/contributions
Ideas, and contributions to this style are very welcome, please use the OpenHikingMap Github issue tracker or, if you don't have an account on github, you can use Talk:OpenHikingMap
Warning : If you want to report problems or have questions about the tile.openmaps.fr tile service (outage, slow, unavailable) please use the github OpenMaps tracker

Is the wiki really the best tool for creating a map legend ? just wondering...
Frequently asked Questions
Garmin version ?
No, there isn't. Having a apache/tirex/mapnik/postgresql/osm data rendering stack is very different from having offline maps in a garmin, I don't plan on maintaining a Garmin version of this map
Off line version ?
See "usage policy" up here, it is possible, but since there are limits for downloads you will only be able to collect small areas.
Why are datas updated so rarely ?
Indeed, the data from OpenStreetMap are re-imported manually every two years or so. And it is not by choice, but by constraint : My server's storage are rotative disks and the whole import process takes around 3 weeks... (yes, you read it well, that is a 3 consecutive weeks non stop import !) During that time the server is disk I/O saturated and all others operations on it are slown down as hell. And that is why I rarely update datas. To give perspective, when I had access to large enough NVMe drives, the exact same process took around 20 hours. sletuffe (talk) 13:39, 12 December 2024 (UTC)
