Track snap to road and attach navigation instructions

The actual method by a simple track import has the tendency to place “waypoints” close to where the track changes direction. Such means that you often end up near the critical road junctions. Result is +/- similar as with other such applications. lnspection and repair is time-consuming, new design faster and more qualitative

Therefore this alternative using “distance tickmarks”. The chance that a tickmark shaping point will fall at a critical place is less, even when using relatively high tickmark shaping waypoint density which ensures a more faithful reproduction of the original without many manual corrections.

FUTURE GOAL !
ACTIONS MUST OCCUR AUTOMATICALLY AFTER IMPORT OF A SIMPLE TRACK.
Demo function test.
Items in “Italic” are currently not available or must be created by external tools

APP.

  1. USE DECENT quality TRACKS. (Motorbiking traject)
  2. DISPLAY: Use the (red) track as visual helper template guide.
  3. CREATE: New (blue) navigation route by the imported track.

TO DO by user.

  • SELECT and import a simple track
  • SET: Select the best fit Router Profile.
  • SET: Snap to street AND Cleaning range.
    - HQ tracks:10m (little or no difference from the OSM road pattern)
    - LQ tracks: 20m (differ greatly from the OSM road pattern.
  • SET: Select a “Shaping tickmark” distance. (Kurviger waypoint limit = Max 200)
    - Long distance: 2.5 km
    - Medium distance: 1 km or 0.5 km
    - Short distance: 0.25 km

TO DO by the AUTOMATIC.

a. IMPORT: After track import, the app adds the temporary distance “Shaping tickmark” waypoints for the formation of the new navigation route.

b. SELECTION: Only “Shaping tickmarks” within the snap range of a street are to be promoted to be route references. Such prevents that “lost” unprecise located “Shaping tickmarks” are disturbing the primary route built.

c. CLEANING:

  • After calculation delete “Shaping tickmarksthat have a nearby U-turn point in range.
  • Such triggers a recalculation with a more optimal result.

d. FINE TUNE CONTROL by USER: Manually correct minor traject deviations by using the (red) visual reference track template.

e. FINAL: Save and export without the many “Shaping tickmarks” as a Kurviger navigation file.

“Track snap to road and attach navigation instructions”
The Kurviger app has the potential to optimize this.

What is the topic’s subject, map matching?

Routing provides the turn instructions to navigation.

So this topic belongs to routing and how routing is calculated from import.

Please do not edit multiple times the posts.
Edits have no notifications, so they are lost.

It is still not clear what is being discussed here.

Is it about routing after import a GPX track
or app’s “Settings | Navigation | Snap to route” option?

Created a file with high density (1km) distance tickmark shaping waypoints.

Due to the high density, it is virtually harmless to remove a badly located one
But coincidentally the result here was also 100% u-turn error-free.
The resulting .kurviger file.

Disturbing anyway are the many Shaping Point map Icons.
