Ascents and descents #441

Closed mic140 closed 10 months ago

mic140 commented 10 months 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.
