Dear แดนสรวง วงศ์สรรคกร, Your recent edits changed major highway classifications, which can disrupt routing. Most have been reverted. Please start with smaller local improvements and discuss major changes with the community first. Best, Julien

Your recent changes to highway classifications conflict with the existing data and don't align with Thailand OSM guidelines. Please review the highway classification before making such edits. In the future, it’s important to ensure changes are consistent with the community standards.

Hi Michael, that sounds great! I’m based in Chiang Mai, though I’m more into off-road motorcycling than hiking. I’ve been improving and maintaining OpenStreetMap in Chiang Mai for the past four years and regularly contribute to mapping tools and wikis for Thailand and beyond.

You might find this hiking guide helpful for mapping in Thailand—it includes useful links to local hiking and OpenStreetMap communities:
[WikiProject Thailand/Hiking Guide](osm.wiki/WikiProject_Thailand/Hiking_Guide)

Visual examples will be added in the near future.
Happy hiking and mapping!

Hi Michael,

Thanks for your contributions! You may have noticed that I updated the highway classification and permissions. Are you familiar with OpenStreetMap tagging conventions? Permissions are typically based on signage and legal aspects rather than physical characteristics.

If you'd like to recommend this track for walking, consider using `sac_scale=strolling` or `sac_scale=hiking`.

You can find more details here:
🔗 [Highway Tagging](osm.wiki/Key:highway)
🔗 [SAC Scale](osm.wiki/Key:sac_scale)
🔗 [OSM Thailand Project](osm.wiki/WikiProject_Thailand)

Let me know if you have any questions!

Cheers,
Julien

Cool. You're not alone, and I haven’t been mapping as long as you :D There’s always something new to learn and ways to improve, and OSM is great for that.

Hey Paul, thanks for reaching out own this topic!

The main reason these tag combination exists is to educate local mappers to use the appropriate scale tag instead of legal access tags which were heavily abused locally.
While using bicycle/foot/motorcycle/horse=yes can be technically correct if the way is legal and accessible, it has no effect in Thailand since paths/tracks are by default legally accessible to all kind of vehicles.
Such scheme led people using `bicycle/foot/motorcycle/horse=no` values on difficult/impossible ways which has been a subjective and conflicting matter.

Also I believe some values is better than none because in Thailand many paths/tracks were added from unknown source (imagery/import) and sometimes do not exist, so having some info when we know someone use a path on mtb is better than none.

But I am with you that these undocumented tags may cause issues with software maintenance (StreetComplete?), so a few options are possible:
- Remove them but we loose some info on whether those ways were feasible with a certain vehicles (hence exists)
- Convert them back to legal access tags (motor_vehicle/motorcycle/foot/horse=yes) and find another way to educate mappers
- Move them to a prefix tag like `fixme:smoothness=unknown` or similar.

Your thoughts ?

Best,
Julien

Hi cdohrmann,
Thanks for your contributions!

Just a heads-up—please don’t downgrade unclassified/tertiary roads to highway=track just because they’re unpaved. Road classification is based on function, not surface, so it's best to use tags like tracktype=grade2, surface=compacted/gravel, and smoothness=bad/very_bad instead.
If your map renderer doesn’t support these, you might find GaiaGPS and other apps more useful.

Also maxspeed should only be used for legal speed limits, not practical ones. If you really want, you can use maxspeed:practical, but it’s not recommended since it’s pretty subjective.

I’ve been working to keep tagging consistent in Northern Thailand, so I’ll need to go through and fix these changes manually. Would appreciate your help in keeping things aligned—let me know if you have any questions! Best, Julien

Hi Dave,

This is an old topic, but I wanted to check—do you typically use *maxspeed* for actual legal limits or practical considerations? I've noticed some mappers applying *maxspeed* heavily for practical reasons, but this should either go under *maxspeed:practical* or be removed altogether since it's too subjective.

Cheers,
Julien

Hi Dave, feel free to remove. Those ways that are clearly visible from imagery but were added without local knowledge, I tag them now as highway=road. Cheers, For more info: https://community.openstreetmap.org/t/improvements-in-thailand-reducing-the-risks-of-armchair-mapping/123857

Hi Killar,

Could you clarify what you meant by `highway=path + motor_vehicle=yes`? Are these paths wide enough for 4-wheel vehicles (like `highway=track`), or are they only suitable for motorcycles (`highway=path + motorcycle=yes`)?

Just a heads-up: using legal access tags to indicate physical suitability is discouraged in Thailand. You can find more details in our wiki: [WikiProject Thailand](osm.wiki/WikiProject_Thailand).

If I don’t hear back from you, I’ll assume these are narrow paths suitable for motorcycles and adjust them accordingly.

Best,
Julien

Hi Killar, thanks for your contributions! If you're familiar with the area, that's fantastic. Road classification upgrades are much appreciated, along with any GPX traces you can upload. For more details on the origins of these unknown road classifications, check out this link: [Improvement in Thailand - Reducing the Risks of Armchair Mapping](https://community.openstreetmap.org/t/improvements-in-thailand-reducing-the-risks-of-armchair-mapping/123857).

Merci Marchoh44 pour ces précisions. Pouvez-vous confirmer que les ajouts de chemins/pistes ont été réalisés à partir d’un relevé sur le terrain ? Si c’est le cas, pourriez-vous télécharger vos traces GPX sur OpenStreetMap afin que nous disposions d’un enregistrement en preuve ? Merci ! osm.org/traces

Thanks for your contributions! FYI I have corrected the name tags (Thai should go into name and name:th, english into name:en) and recreated the place=village as node. You can read more about Thailand's tagging guidelines at the link below. If you have any questions, feel free to ask! Happy mapping :) osm.wiki/WikiProject_Thailand

Hey, thanks for reaching out!

Sorry for the misleading changset description here. So, I've been removing the `highway` tag from geometries that I previously added based solely on imagery. After some global feedback, I realized that without additional sources, these geometries might not actually be paths—they could even be something else, like streams. Some people suggested I shouldn’t add them to OSM, while others recommended tagging them as `highway=road` or `highway=path` if I’m reasonably confident they’re actual paths from the imagery alone. As you know, OSM doesn’t have a built-in way to distinguish between verified paths and those from unknown/limited sources. Instead of deleting these unverified geometries, I’ve left them as-is to encourage other mappers to survey them. I’m not completely satisfied with this approach, but I’m actively exploring alternative solutions. Hope this helps clarify!

Hey, just curious of this unclassified to tertiary upgrade, I don't see any refs. How do you see the wiki justify it ?

Thanks a lot for your contributions! Just a friendly tip: try to keep your changes smaller, like focusing on one country at a time.

Please explain again the downgrade from residential and the additional of unsigned legal access tags ?

Hi Napitta, could you please explain why you downgraded this road to a path ?
