I'm a new user of Locus Pro and BRouter. I use the downloaded offline map "OSM regional - Hike and Bike".
I use the "from", "to", "nogo", "via" points with a user-specified BRouter profile for my navigations.
I'm somewhere in Switzerland having only my smartphone with me, I'm somewhere on a route and need to navigate to the next closest (freely available public) drinking water fountain according to BRouter mimized total costs.
I know OSM has data for drinking water fountains.
How can I do the navigation?
I don't need especially the shortest BRouter cost minimization. It would be good enough to know where the next three drinking watwr fountains are, then I can navigate individually.
It would also be okay just to show the different drinking water fountains in the range of the next 50 km on the map.
