Driver for decoding the density value as a generic observation, coming from a Navitracker Density Probe. Towed behind a vessel, this probe measures continuously the sediment density.
Besides the density value it outputs also the depth, the x-offset and the layback of the sensor.
In order to decode this depth, please see document Decoding Depth Observation.
In order to decode the x-offset and layback, please see document Decoding Position.
