The Simplify command reduces the number of points in a track or shape. Use this command to smooth out a jagged tracklog, or to
reduce the number of points in a track so it will fit in your GPS receiver's tracklog memory.
To simplify a track or shape, do the following:
View a map, Track or Shape List, or an Elevation Profile.
Right-click on the selected items, and click Simplify.
ExpertGPS will remove points in the track which are close together, which gives the track a smooth appearance while maintaining
the overall shape of the original track. Each time you apply the Simplify command, more points will be removed. At some point, the
track will begin to lose its original shape. Click Undo to cancel the last Simplify command.
