tagging incline direction on ways with mtb:scale:uphill is useful as otherwise you need high-quality elevation model to do routing, and in some cases it may be unavailable at all in sufficient detail
I wanted to systematically tag mtb scale info in some places to improve routing for bicycle trekking. Some people (like myself) are NOT interested at all in MTB routes but mtb:scale=1 (or just mtb:scale=0) is still fine for them. So mtb:scale=1 mtb:scale:uphill=3 is fine downhill but not uphill for such people, but it is hard to check in which way given path goes uphill This is also recommended by wiki: https://wiki.openstreetmap.org/w/index.php?title=Key:mtb:scale&uselang=en#mtb:scale:uphill=0-5 So I wanted to systematically tag missing incline tags, as even without exact value it is already valuable info for routing. But what can be done in cases where there is no real incline but path goes through series of up and down hops? In many cases it is deliberately engineered (legally or not) and looks often like https://www.moredirt.com/photo/91766 https://www.zip06.com/local-news/20220622/rockland-preserve-pump-track-is-officially-a-hit/ https://www.bikehinton.com/hinton-bike-park ------------- Would it be fine to tag incline=up_and_down in such case? https://taginfo.openstreetmap.org/tags/incline=up_and_down has some minimal use already. Or maybe incline:variable=yes? Splitting such way into incline=up / incline=down segments is too much for me and I was splitting footway into 20m segments to mark changing surface/lit status. ------------- And why I want to tag some incline value? Because I want to do it systematically for all such ways. See https://github.com/streetcomplete/StreetComplete/pull/4385 for the context (I want to also add it to StreetComplete if it will be accepted there).
