For each dredger a data file must be specified with the location of the dredger (the two coordinates in the geographical domain), the dredge rate (using dry weight) and the dredge spill (in %).
You must also specify the map projection (Longitude/Latitude, UTM, etc.) in which the horizontal location of the dredger location is given.
Positive dredge rates correspond to dredging. Negative dredge rates correspond to dumping.
