[Tagging] Mapping gentle slopes?

[john at jfeldredge.com]

Of course, this will require breaking the way into segments each time the slope changes between uphill and downhill.  On some terrain this won't be an issue, but on rolling terrain you may have to have a great many nodes.  Also, the slope will need to be determined by someone on the ground, as it may not be obvious when looking at an aerial photograph.

Is the incline=* key[1] what you are looking for? You can specify that a
way goes uphill (incline=up) or downhill (incline=down) relative to the
way's direction. You can also use positive or negative percentages as
values to more precisely indicate the way's steepness.
