Context
It is important that the colours used in the velocity measurement (ADCP) views is adapted to the actual velocity values. The intensity of the colour reflects the magnitude of the velocity. If the color range used is larger than the data would indicate, you may lose valuable information abou the velocity differences. If the opposite is the case, it will also reduce the quality of the information.
The velocity measurement (ADCP) views provided by the EK80 system present the data using colours. This information is shown using either a bipolar representation or a gradient single colour representation. The colour and/or the saturation of a colour indicates the magnitude of the ADCP data. To achieve the best possible presentation of mutliple variations in velocity and/or speed, the maximum values for the colour
scale must harmonize with the highest magnitudes in the ADCP data. The maximum values representing the most saturated colours are defined with the ADCP Colour Span function.
Note
The changes you make are by default applied to all views in the current ADCP presentation. By clicking inside an ADCP view for velocity, you activate the view and options for ADCP Colour Span will be available in the Active menu. In order to use different ADCP colour span settings, use two separate ADCP presentations.
