I am having errors interpolating data between the shoreline shapefile that I've set and the path I took with my fish finder. In the first pic, you can see that the shoreline overlaps with up to 10 feet of water despite the shoreline obvioiusly being at 0 feet. Yet there isn't any crossing between my acquired data and the shoreline, as is shown in the second pic. How can I fix this?

I have the same "issue" on some islands. Not sure why as most islands don't have it.

Don't think there is much you can do about it. It doesn't bother me that much.
