Columbus Data Collection and Analysis System

for Corps dredging contracts (Rosati 1998).

The SI system collects and records measure-

ments from shipboard sensors, calculates the

dredging activities, and displays this infor-

mation using standard reports and graphical

displays. In addition to automatically calcu-

lating TDS, the SI also collects three-dimen-

sional positioning of the drag head(s) and

horizontal coordinates of disposal, parame-

ters that are desirable for any automated bin

payment method used by to the Corps to

ensure that dredging and disposal are con-

ducted within the authorized locations. The

inspector screen on the Corps computer

automatically backed up, and later archived to allow transfer of the data to other locations. The
