Title: Locus Navigation experimental
Post by: 0709 on November 20, 2017, 18:21:50

”Discovered that actual Locus can easily do this” and is 100% functional.

Perfect for a test to confirm that the similar, but actually not supported but preferred track navtrkpt method can do the job !
Disadvantage of a direct route is that nearly all external programs or gps do not like such direct gpx (rte)routes.
So is NOT compatible (conflicts) with most well known already operational gps software and programs.

Is a Test !!!

Route(rte) navigation by gpx file.  A direct gpx (rte)route  (Locus Import only !)
The routepoint(rtept) density is exactly the same as trackpoints(trkpt) in tracks(trk).
Good to know !
(Auto)(re)calculate routes in Locus is toward the (reference) target Via Points !
 
Instructions in routepoints (rtept).

Standard routepoints contain only basic elements: Longitude, Latitude, elevation (optional), time (optional).
These intermediate routepoints, treated as shaping points, do not lead to alerts nor give distance values.

Routepoints that do contain extra as name, cmt, desc, sym or type are promoted to navigation points.
Only these routepoints lead to navigation or via point alerts and give distance values @ navigate.

Advantages.

- Manage/separate the poi waypoints without any risk to damage the navigation.
- Easy import, navigate without "must" set: "Merge waypoints with imported track".
- Less fragile than the trk_navwpt method with the more vulnarable associated waypoints.
- Compact POI wpt_list not cluttered by many associated wpt's as by the trk_navwpt method.
- Synced gpx files to pc offers extra edit tools or an alternative for only Locus edit.
- Add individual freely positioned wpt's(poi) into the gpx file. (Locus can't, function is not offered)
- Timestamps are not obligatory for navigation,  but can be attached according to expected speed.

Edit <sym>text by (pc) * GPX Editor or Android Notepad ++ etc.
GPX Editor:  https://sourceforge.net/projects/gpxeditor/

The exact <sym>text must be known.
In attachment: 3 gpx files to exactly find out.

1. The Garmin Icon list by <sym>text. (Wpt) <name> is identical to <sym>text.
2. The Locus Icon list by <sym>text . (Wpt) <name> is identical to <sym>text.
3. The Locus supported Navigation turn Icon list by [EN]<sym>text. (Route) by rte_navrtept.
Import route into Locus, choose trackdetails -> Waypoints. (Rtept) <name> is identical to <sym>text.

Elements gpx in the Locus navigation (rte)(route) example files.
http://www.topografix.com/gpx_manual.asp

<RTEPT> (routepoint).
Required Information:
<lat> Latitude.
<lon> Longitude.
Optional Position Information:
<ele> Elevation.
<time> Date_time.
Optional Description Information:
<name> Name. (Local language)
<cmt> Comment. (Local language) Displayed in Locus top panel @ navigate.
<desc> Description. (Local language)
<link> Link (to photos) related to objects on the map.
<sym> [EN] Symbol. Important Locus Icon element, contains the navigation instruction.
<type> Type. Locus does not use.


- Supported navigation turns by [EN]<sym>text are auto-translated in local language TTS turn commands and a direction turn icon is shown @ navigate
- Unsupported points by <sym>text are promoted into Via Points,  announced by TTS <name> and via point Icon shown @ navigate

Find the supported Locus navigation turns by the [EN]<sym>text in the attachments.

Could you give a little hint on what you are experimenting on? It's always hard to tell, what you want to tell :-)🤔

@uatschitchun. See > Advantages.

Suggestion Idea Locus Route Planner. (Non existing function in actual Locus !)

Router adds timestamps according to +/- realistic (personal) speed expectations.
Set your personal avg speed, visualised in the Locus % Slope trackcolor legend.
Personal variable speed within the % Slope zones by using the gpx <ele> data.
Dark Blue_36kmh - Green_16kmh - Red_2kmh

(https://www.imgdumper.nl/uploads9/5eaffcb664eed/5eaffcb6630dd-Personal_range_by_activity.png)

(Off bike 2kmh = non advised traject).

By the way...freely changing or adding timestamps is uncritical when using the direct route (rte) navigation mode as the method does not need any "associated waypoint" for secure navigation.

Yes, I had proposed before that at least average moving speed should be a "custom defined value" by every user(according to personal fit level,age,sex,terrain,activity etc.)
Locus already kind of have speeds based on different activities defined(in navigation/more/Travel time/ like mountain hiker --with flat moving speed=5 km/h, 700 Vertical meters/hour descending and 400  vertical meters/hour ascending speed etc)
We can define ourself the ascending and descending vertical speed and Locus should compute the time,according to these user defined values.
Do you also have a verified slope range set for mountain hiking?But here the gradation is larger -40 --- +40 % maybe ?

If Locus could analyze the actual  track recording during navigating a track,it would be best option for adjusting time estimate (because everyone is different... this way Locus can make a personalized slope range set chart with speeds according to everyone's fitness level)
But even if this is too much to ask, maybe if Locus would let us custom define the speeds according to slope angle(I can guess the average speeds for every slope range from the past experience).. this would also be good enough for accurate estimate the time to navigate the track

@ poutnikl had proposed an algorithm for ETA in this old  thread:

Proposal.

If the gpx point <cmt>text in the top panel does not fit into single line:  < move < text.
(Total characters in single line depends by portrait // landscape // screen dpi // top bar lettertype etc.)

Suggest: By config.cfg select prefered top panel lettertype.
By move action text 'auto fits' into a single line top bar.
Large letterype <=> Small lettertype
+:  Important for the older guys.
- :  Less map view.

Open in browser to see  <=<=<= Move text  <=<=<=

Lorem Ipsum is simply dummy text.

Another experimental mode.

Locus navigation by a single gpz file (no typo) (Locus actual = by zip > read document).
Navigation inclusive support and transfer of images & (no limit) Icons in points by a single file.

Video example.
