Delete duplicate positions

Thin out a track by selecting redundant positions first and deleting them in a second, explicit step.

Select by distance

Select all positions within a distance of N meters of their predecessor. finds points that are too close. Press Select to mark them.

Select by order

Select all positions but every Nth position. keeps a regular sampling and removes the rest. Press Select to mark them.

Select by significance

Select all redundant positions with a threshold of N meters using the Douglas-Peucker algorithm. finds points that barely change the shape of the track. Press Select to mark them.

Delete them

Delete selected positions removes the marked positions from the list. Selecting changes nothing until you delete, so a selection can be reviewed in the position list first.

Undo

Edit → Undo steps the deletion back if you change your mind.

If you would rather control which positions go, see The position list.
