|A specially adapted work boat with four sounder transducers mounted on booms supported by floats is equipped with an accurate DGPS system. The operator drives the boat at 4 knots up and down the canal covering the required area.|
|A customised version of Portable Navigator logs the data and plots the swathe showing the boat and the booms on the chart. The logged data is later exported to a GIS package for display and analysis.|
|During logging Portable Navigator displays and logs the position of all the transducers, using the heading of the work boat and the sensor geometry. The optional Swathe Plot enables the helmsman to see the ground covered.|
