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.

@0709wiwiwi thanks for the suggestion.

It is possible, however when mention "track edit",
you probably mean with a desktop editor, which not many users will do.

Advanced users with desktop editor can use the find & replace to remove shaping points.

Processing routes in app requires the shaping points to closely follow the original tracks.

NEW to be applied IN the app. (No recalculation.)
Click navtrk | More | Remove shaping points | Remove type shaping, sym pass_place, src & keep all existing trackpoints.

NEW to be applied IN the app. (No recalculation.)
Click navtrk | Remove SINGLE shaping point. | Remove type shaping, sym pass_place, src & keep the excisting trackpoint.

Undo & Redo at (re)edits is your best friend.

@0709wiwiwi thanks for the extra details.

So the idea is to have 2 different delete functions in the menu of the shaping points:

• Delete (with calculation)
• Delete without calculation

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

In other words.
PROMOTE in a gpx track one or more already existing gpx trackpoints.
The number of total track points and their location remain unchanged.

A. PROMOTE a gpx track into a BASIC gpx navtrack.
This enables all further editing.

• Change the first and last trackpoint into a via trackpoint without recalculating. = NEW

B. PROMOTE one or more trackpoints into shaping trackpoints.

• Change one simple trackpoint to shaping trackpoint without recalculating. EXIST
• FILL with multiple shaping trackpoints without recalculating. EXIST.

C. DEGRADE one or more shaping trackpoints into trackpoints.

• DEGRADE one shaping trackpoint to trackpoint without recalculating. = NEW
• Degrade ALL shaping trackpoints to trackpoints without recalculating. = NEW.

D. Convert shaping trackpoints into via trackpoints without recalculating. EXIST.

This allows you to (re)spread the shaping trackpoints freely this entirely as you do wish.
Nicer spaced shaping trackpoints may possibly be more favourable in a route (re)calculation.

Note.
The better protected VIA trackpoints cannot be totally demoted at once.
VIA trackpoints can first be converted into shaping trackpoints. EXIST.

A: No problem, add a sym pass_place and type via. Done.
Offers a very basic (no turn) navigation track.
Only extra that it offers is the off route alerts.

[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]

I know that.
Just try it see and feel what I mean.
Use and test by recorded gpx TET track.
Make it routable as described.
Isolate the non routable navtrack sections.
Indicate these in the section target trkpt by scr "track".
Calculate the routable sections.
Result is a partly calculated navtrack inclusive some non routable original sections to FOLLOW visually.

[devemux86]

Do you mean a way to convert an imported track to a route with partially calculated sections?
With a workflow like the following?

• Import a GPX track
• (A) Set first / last track points to start / end waypoints (without calculation)
• (B) Add shaping (or via?) points at track points (without calculation)
  (this "route" still does not have instructions)
• Calculate the sections we like with specific profiles (curvy, etc.)

[0709wiwiwi]

Yes indeed correct.
