A way to identify where the edged of the MB or SS swath within the map window. This could be in the form of a simple horizontal bar that changed under the vessel as the swath width changes, lines that are drawn on the edges of the swath. Currently only way to see swath width in map window is to change the martix transparency.
Currently we can do this with the coverage DLL. Adding this into the next visual of Survey Core is a good idea. For now the Coverage DLL is your best option.
