Recorded GPS data can contain a large number of redundant points which make your documents harder to work with and increase file size.
To automatically remove unnecessary points, select the tracks or track segments you wish to optimize using one of the selection tools and select the menu item Selection → Optimize...
You can increase the optimization strength to remove more points. Adze will show you a live preview of how many points have been removed and what the resulting track looks like.
Click Done when you are ready to apply your changes.
