Hi, any tags to indicate the maximum and minimum elevation on a mountain route?
“ele:max” & “ele:min” discarded because they are for bodies of water according to wiki
https://wiki.openstreetmap.org/wiki/Key:ele
or acceptable by
https://wiki.openstreetmap.org/wiki/Key:ele:max
“The maximum elevation of a feature above sea level, in metres.”
Personally, I can see the value in using those tags on features other than reservoirs - such as in your example.
Note, after all, the Wiki is just documenting current usage.
Since this information can automatically be calculated from SRTM data, I don’t think it should go into OSM. Nearly all software doing the calculation is using this approach anyway.
