I have often noticed that a track that I record has a constant error across all points in the track. For example, I might hike along a trail, and when I download my track to Topofusion later, I can see the actual trail on the map, and my track is offset by a few feet. It would be interesting to be able to apply a correction to all the points in the track, to manually correct for the visible error; maybe something like "move all points 7 feet on bearing 71 degrees" or some such.
Is there any way to try this in TF? If not, is there any other (preferably free) software that can apply such a correction?
