Please note that now you can also use the tool on the Web App: www.waterspeedapp.com/webapp

In case of errors from the GPS or if you forgot to stop when back to the land, you can use the tool "Trim/Cut/Remove/Crop track" to amend the map. Click on the icon in the right-up corner to start it.

1. Use the slider to select a portion of the track. It will color in grey the beginning and the end of it.

2. Now you can choose:

a. Trim, to remove the grey part, at the beginning and the end

b. Remove, to delete the part in the middle, with colored track

c. Crop, to create a new activity using the internal part, with the colored track

d. Calculate statistics and show on the page, using the internal part, with the colored track
