Re: Osmand claims it uses elevation data - but it doesn't

For bicycle, there is similar rule - the principle is the same, it just uses different values. Of course, the differences are here much bigger (easy ride x race). But as a rule of the thumb, I would suggest something around speed 20 km/h and 800 vertical meter / h for "faster" and 15 km/h and

In an update to OsmAnd about a year ago, they introduced for the first time Naismith's rule to factor elevation into the calculation of WALKING times. Back then, I tested it and it worked. Numerous refinements to Naismith's rule have been proposed, but a fundamental uncertainty is one's

Ah, right. And agreed. The time calculation on OsmAnd does not take elevation gain or loss into account. On Saturday, May 25, 2019 at 2:56:34 PM UTC-7, jot ess wrote: > > Obviously I have not made my problem clear. I have not systematically > tried whether routing is different with

Obviously I have not made my problem clear. I have not systematically tried whether routing is different with different options. My point is, that elevation is not taken into account for calculation of time. I tried different options for a hill nearby (where there are no different

I tried this on possible bicycle ride around here. With elevation data off, it routed over a ridge using fire roads. With the option on, it took a much flatter, but longer, route via surface streets. -- You received this message because you are subscribed to the Google Groups "Osmand" group.

This is just anecdotal and someone with an understanding of the algorithm would have a better answer, but using elevation data, I've made this work for a couple of hiking routes where the two routes are close to each other and (of course) wind up in the same place. One of them is in Yosemite,

Hi all, I have been reading a bit in this forum and my impression is that I am not alone with my question and there has not been a clear answer yet: Osmand+ claims it uses elevation data - but obviously it doesn't. Or only under certain circumstances. When I use Osmand+ for bicycle routing
