Strict Route Navigation only for imported GPX tracks

Hannes shared this idea ago

Declined

Hello,

I use Navigation in Locus in 2 situations where my preferences for routing differ:

1) I pre-download a certain GPX track where I want to follow strict the way pre-defined without recalculation or modifications during following the track.

2) I use BRouter to calculate a Navigation to a destination when I am on my way. In this case it is good when it recalculates during the ride e.g. I decide to follow a different way but still want to go to the destination.

Unfortunately Locus cannot be configured to differentiate between those two methods when it comes to recalculate a route btw. stay on the fixed track. Whether there is strict routing or recalculation possible in the settings.

Would it be possible to implement a setting to allow different settings for "strict route calculation" depending on (1) fixed Tracks (2) calculated tracks?

Another option would be: When I click on a certain track->Navigation: There should be a checkbox to chose "strict Navigation" for this time.

P.S The same applies to Guidance instead of Navigation

I like this idea 0

? Settings > Navigation > Route re-calculation > No auto recalculation. Does not work for you ?

If you would read the whole thread you would understand my problem. This setting works but I do not want it to be active for all sort of Navigation.

I have read the whole story, comrade, but I still don't understand. Anyone? Sorry = End.

Sometimes I download a certain GPX (planned route). Here I do not want Locus to recalculate = fixed

Sometimes I just use Navigation on my way to a certain destination. Here I do want Locus to recalculate = not fixed

Is it clear now? In the second case the routing is done by a program (BRouter) and I want to be able to use other ways on my way and Brouter should in this case recalculate the route when I leave the route calculated by BRouter.

OK. I also download external track_routes that do contain very functional Via Waypoints. (Navigation by Point Priority). When ontrack there is complete navigation silence except when nearing the Via Waypoints that do contain a next instruction. But I do expect Locus to have an auto-recalculation with hints when going off track (for any reason) also on such downloaded tracks from external sources.

Hello Hannes, Willy,

for me, it looks like an ideal adept for using "Presets" system.

In the end, you only choose "Navigate" and then choose one preset that set all the necessary settings at once. Usable solution?

Hello Menion,

thanks. I will have a look at it and the preferences that could be set when I am back home but it seems like a solution for this problem.

Hello Menion,

I had a look at the presets option.

First, unfortunately there is only a setting for route re-calculation but not for strict route following.

Second, I do not really understand the difference between route re-recalculation with route priority and static routes although I have read your explanation on your website?

Hello,

this is correct, "strict following" is missing in presets. Anyway, whole "recalculation" setting is there so you may have preset that have enabled recalculation and one that has disabled this setting.

Difference between ... "static routes"? What is it? The strict route following settings has an effect, that it force you to visit all points along the route. When this setting is disabled, you may freely take a shortcut and Locus Map detects when you are back on route and will continue without any problem. "Strict route following" is the quite advanced feature and with the recent change in navigation we did last months, I'm not even sure how much useful this setting is.

Generally, I think you just need to quickly enable and disable recalculation. And this may be most easily done with Presets. Does it make sense? Feel free to ask if not.

"I'm not even sure how much useful this setting is."

Yes, an already older item even before Locus-Brouter auto(re)routing was created ;-)

"Strict route following". Well "hidden" in Navigation Advanced settings, and that is fine.

A 'dangerous' setting that could bring a lot of 'misery' for normal standard use.

Created for 'circuit drivers' as for example (must) strictly (no shortcuts) follow MTB tracks, that have multiple out and back path overlaps inclusive multiple (different levels) path crossings.

The negative, so for experienced users only: Even when you miss only ONE single trackpoint Locus will protest!

Ex. GPS unlock in tunnels in > out. Only solution is manual correction > by tap navigation Icon > Nearest point.

Advise: As 99% of the users do not need, keep away, unless you precisely know what you are using it for.

Well written, thanks Willy.

OK, thanks. I disabled strict routing and will have some experience with different methods of recalculation that can be done via Presets.

@0709 I estimate that you are a biker, too. Do you have some recommendations about the distances that should be set for riding? I mean the two distance values that could be set (1) for the start of a re-calculation and (2) for changing to guidance mode (in advanced settings)?

My actual settings. New phone, good quality gps.

Navigation Route recalculation trigger @ 50m

Navigation Out of track alert trigger @ 32m

Advanced settings > Maximum allowed deviation @ 32m.

Old phone low quality gps.

Route recalculation @ 100m.

Out of track alert @ 75m

Maximum allowed deviation @ 36m. (not very important imo = graphical hint only by showing guiding arrow)

Find my own used memo "hint" note.

Original text by Garmin, converted to Locus map operations.

Hope it helps.

Navigation > Locus_Brouter installed !

How do you know whether you should use (auto)(re)calculate by Point Priority or Route Priority or None ?

Point Priority is best suited for reaching a specific destination, or set of (via)destinations, when the precise path being taken is not important. If you go off course, the path toward a nearest Via Point will be recalculated using available roads and/or trails based on your current location.

Route Priority is best suited when it's prefered to travel on a specific path to reach the desired destination. If you go off course Locus will navigate you back to an optimal nearest trackpoint location using available roads and/or trails based on your current location.

No auto recalculation is best suited when it's necessary to travel on a very specific path to reach the desired destination. If you go off course, Locus generates an out of track alert. It is up to the user who has to decide how to rejoin the course.

@0709 Great! Thank you for this detailed explanation!
