Ascents and descents #441

Closed mic140 closed 1 year ago

mic140 commented 1 year ago

If you compare the elevation graph and the general values of ascents and descents, you will notice their obvious discrepancy. Can this be fixed somehow? Route link: https://mtb.waymarkedtrails.org/#route?id=16294949&map=15.0/53.8944/27.4715 IMG_20230911_091818

waymarkedtrails uses a source for altitudes with a rather low resolution. That means that ascent/descent are somewhat approximate. For a route as flat as this one, it is close to impossible to distinguish between real ascents and noise. So unless we get better altitude profiles, this is a won't fix, I'm afraid.

But somehow you were able to construct a height graph that fully corresponds to reality. The question was why the total ascents and descents do not correspond to the schedule.
