US Patent 9367565 Polygon creation for an aquatic geographic information system

A method of processing geo-statistical data includes piloting a watercraft with a monitoring system on a water body, taking measurements of a depth of the water body and the position of the watercraft using the monitoring system, and aligning the depth measurements with the position measurements. The method also includes creating a contour map from the depth and position measurements, creating a polygon on the contour map, and analyzing at least one of the depth and position measurements within the polygon.
