Delete shaping points without calculation

[0709wiwiwi]

Dealing with an excessive number of shaping trackpoints.
It is more convenient to be able to edit a less crowded navtrack.
Action to do:
Convert existing shaping trackpoints without recalculation to simple trackpoints.

Reference: #533 (comment)

@0709wiwiwi thanks for the suggestion.

Routes need shaping points to closely follow the original tracks.
Shaping points can auto hide in the routing appearance settings.

[devemux86]

@0709wiwiwi thanks for the extra details.

So delete single shaping point will be done without route calculation.
We can use the recalculate section or route to do a new calculation.

And a new function "Delete shaping points" without route calculation in the route menu.

Promote in a gpx track one or more existing gpx tkpt. The number of total trkpt and location remains unchanged.

A. Promote a gpx track into a simple gpx navtrack. Change the first and last trackpoint into a via trackpoint without recalculation. New.

Change a single trkpt into a shaping trkpt without recalculation. Fill with shaping trackpoints without recalculation. Exist

Change ALL shaping trkpt into normal trkpt without recalculation. New.

Change a shaping trkpt into a via trkpt without recalculation. Exist.

This allows to (re)spread the shaping trkpt as you wish. Nicely spaced shaping trkpt are more favourable in route (re)calculations.

How the (A) is possible without a route calculation? And what is its use?
A normal GPX track cannot be converted to a navigation track (with turn instructions) without route calculation.

All other should be covered by the extra functions I mentioned above?

[devemux86]

But this is still not a navigation track with turn instructions, it remains a normal GPX track with a list of coordinates,
that may be or not on a routable road. So what is its use?

Via and shaping points can be used on calculated routes.

[0709wiwiwi]

Make track routable as described.

[devemux86]

Do you mean a way to convert an imported track to a route with partially calculated sections?

The correct procedure is to import the track as a route with multiple waypoints,
or import it as overlay and construct a route step-by-step by adding waypoints.

Delete one or all shaping points without route calculation will be available in the next version:

• "Delete" one shaping point is already available in waypoint menu (image 1).

• "Delete shaping points" will be available in route menu to delete all shaping points (image 2).
  It combines nicely with the existing "Add shaping points" function with adjustable distance.

• These actions are stored in the undo / redo history of the route, so they be can reverted.

• Delete shaping points is done offline without route calculation.
  If you wish, use the recalculate section or route afterwards.

• Shaping points that can be deleted without route calculation are those that do not define a section with a route profile

Delete shaping points without route calculation is available in:

• Cruiser 5.3.0 Beta 12 #734

See the link for instructions.

Works like a charm! Necessary Shaping points of straight line segments are kept - great! Thanks a lot.
But if I now want to refill the shaping points, "Add names" is missing ... 😕

. . .

I use these names to synchronize my .kurviger file with the .gpx files from the Garmin users - as described in my workflow:

[devemux86]

@WolfgangZ42 Shaping points now display the distance / time to start and destination.

The thing is that fixed names with distance label are not safe,
as they are kept in next calculations leading to confused results.

Are they really needed?

[WolfgangZ42]

they are kept in next calculations leading to confused results.

Good point! I didn't see that because it is the last step for a "closed" route. "Add names" was an option and could be used with the motto "Trust me, I know what I'm doing". 😎
Now I'll think about another solution - and possibly come back to you. 😉

I think I've fallen foul of this new feature on my recent trip.

Wishing to remove several ShapingPoints due to a road-closure, it was more convenient for me to long-press on the map and remove each numbered point (rather than refer to the Waypoints List). This, didn't recalculate the route - a long-press on the route and invoke a manual recalculation refreshed the route layout.

By the roadside, this was confusing as I didn't know the area, but having just tried a simple local route; Adding a ShapingPoint diverts the route but when I delete it, nothing happens - but if I manually invoke it (long-press on the route line), the re-calculation works.

I have tried "Intelligent" and "Normal" in the "Navigation Settings" but neither have any effect... Perhaps I've found a bug or I've just done something silly.

[MotoUKRider]

@WolfgangZ42 Exactly that. What I suggested in an earlier post, was the important bit:

So, if I my route is: S(tart), 1, 2, 3, 4, 5, E(nd) and I pass ShapingPoint "2", find that the road is closed somewhere along "3". I remove "3" and would expect an automatic recalculation between Me+4.

This, quite sensibly, should/would only process the affected "bit" of the route that I've just edited.

[WolfgangZ42]

In navigation mode you can use "avoid road block" with an estimated length of blocking.
Stopping navigation the waypoint "Me" isn't present, so

1. in "intelligent" mode the remove of "3" should recalculate the segment between "2" (not "Me") and "4".
2. in "normal" mode there should a recalculation of the whole route occur.
3. in "manual" mode there should happen nothing, except "recalculate route" is initiated

Unfortunately 1. and 2. don't work this way - as I said, in all three cases no recalculation take place.

[devemux86]

@MotoUKRider In navigation everything is handled automatically:
skip next waypoint, select next waypoint to travel, avoid road block.

@WolfgangZ42 Thanks for the summary, this is how it currently works.

The instructions are mentioned above.

• Note: this thread's idea was to "Delete shaping points" (plural) without calculation.
  (route menu)

• During this process, also the delete of 1 shaping point was made without calculation.
  (waypoint menu) Useful or not?

[WolfgangZ42]

Personally, I would prefer an automatic recalculation to take place after deleting one shaping point in the “intelligent” and “normal” modes.

Many shaping point changes (deleting, inserting and moving) without recalculation can be carried out with “Route calculation = manual”.

[devemux86]

Let's go with what most users expect, delete of a single shaping point is done with calculation.

We'll see if an extra function is really needed and why exactly.
Also "delete" and "remove" translate the same in many languages, which is confusing.
