Off road tracks

[Petra Giacone]

Hello everybody, I am new to Osmand, could anybody help me with this simple issue? I am trying to generate an off road track between 2 locations which I know are connected by an unsaved road (la Via del Sale, in Piemonte region) I am using Osmand 3.13 on my IPad and have uploaded the map Italia Piemonte 256,4MB dated 1/03/2020. I have selected car, selected Off road as preferred map, selected to avoid paved roads, paid roads. Start point: Upega, End point: Limone Piemonte. Instead of showing me the expected unpaved and famous road La via del Sale, it makes me pass all the way around through Mondovi and then up the valley to Limone, a classical way for normal cars. If I select by motorcycle, than it makes me pass on a mountain ridge track which I know to be only for trekking. Any suggestions on what I am missing are appreciated. Thank you. Petra

On OsmAnd for iOS, there are three navigation modes: walking, bicycling (not motorcycle) , and driving.  Driving probably doesn't work for your situation because it's trying to avoid any road not open to motor vehicles.  The other two modes make different assumptions.  All three depend on the underlying data from OpenStreetMap, so, for example, if a road doesn't "show" that bicycles are prohibited, OsmAnd will assume they are allowed.

What happens if you select Walking for navigation, then use some intermediate destinations to further specify where you want to go? (And what do you mean by an "unsaved road"?) 

The Offroad map is one of several map styles. It doesn't determine navigation.

Thank you for your reply.
I meant unpaved roads.
I understand that the selected map (off road) is only a display preference, but is there a way to create tracks on unpaved roads with a 4x4 car?
Thank you

Do you mean osmand routing you throught unpaved roads?
It begins to be possible by adding a profile:
Configuration-> scrolldown->add a new profile

Add a new profile based on the default one
go to navigation parameters for that profile
then route parameters -> preferences, select unpaved roads.
you could also disable toll roads and highways in route parameters ->
avoid roads
Also, in vehicle parameters you could set the default speed to
something low.

Note, all of this is in the 3.6.3 version in Android, not sure if it is
yet ready for IPad althought there seems to be an effort to bring the
functionality for Android into IPad.

Profiles aren't yet on the iOS version.  So for now, there are just three modes to choose from.

After experimenting on the California map, I think this comes down to how a given road is classified on OpenStreetMap--which provides OsmAnd with its underlying data.  And it looks to me like Car navigation assumes that a given road can be navigated by an ordinary passenger car. So if you're planning for 4x4 travel, you might have to use the bicycle or even the pedestrian mode.  And if the route still isn't going where you like, add some intermediate destinations.  

(There's a definitive answer to which kinds of roads the three modes use or avoid. Maybe someone else can help.)

I think that's good advice.

The real underlying issue is that OSM doesn't really have a clear and
complete "this road is passable by this vehicle" data model. Yes, a
highway=unclassified/residential/service should be passable by an
ordinary passenger car, but is not necessarily paved.

highway=track sort of implies passability for 4-wheel vehicles; there
are grades where I'd say at one end, you really need a capable 4WD
vehicle with high clearance, and at the other a passenger car should be
ok. (Track is more than a phsyical description as it is tied up with
the notion that the way represented by it is not a road in the normal
legal sense. Note that while I think this is the majority view, there
is not full agreement on this point.)

highway=path implies that a 4-wheel vehicle cannot pass.

Separately, there are acccess restrictions, and it's a good guess that
if a vehicle cannot pass it will either 1) be tagged not for access or
2) the type will imply.

With all of that, keep in mind that all data is subject to being wrong.

If Petra wants to make 4WD routing work, I think a routing mode that
allows some tracks is needed, perhaps as a variant of car.

I would not assume that the car mode gets the subtleties of tracks
right.

 Hello,

I use OziExplorer PC and Android, I convert a .plt trace of Ozie to .gpx.

I import it in trace, make it visible, and choose it as destination.

Osmand + does not take care of the path, the road or the surfacing, it keeps me on track.
