Resolution: fixed
Status: newclosed

In 14868/josm:

fix #17443: improve performance for GPX layer action "Download from OSM along this track"

  • use Path2D.append() instead of Area.addToDownload() to calculate the area around the track
  • use only the intersection of the original area in recursive calls of DownloadAlongAction.addToDownload()

Even complex tracks which cover huge areas are now handled within a few seconds insteads of several minutes
Possible improvement: remove progress monitor in DownloadAlongTrackAction and add progress monitor for recursion in addToDownload() in DownloadAlongAction

In 14872/josm:

see #17443: increase threshold value reg. display of progress bar to reflect new calculation speed
With normal sized gpx tracks the calculation is done in a few miliseconds
