With MIKE Zero Release 2017 it became possible to plot data from dfs1 files in the Result Viewer.
Due to the large flexibility of plotting options this functionality can also be used for e.g. plotting vectors representing measured ADCP data.
Consider a dfs1 file with measurement data in items as follows:
(Items 6 and 7 have been derived from items 4 and 5).
The measured velocity vectors can be shown in Result Viewer by first specifying the location of the spatial line (and hence the point positions) by the Geographical position given by the Easting and Northing coordinates.
To draw a vector arrow, select the point symbol type as Enhanced metafile and select a customized point symbol (arrow symbols can be derived from here)
You can size and rotate the symbol in various ways. In this example point size vary with the Current speed item and the point orientation vary by the Current direction item. It is possible to scale the size of the symbol by a fixed point scale factor and furthermore to add a fixed rotation of the symbol (e.g. to account for ‘coming from’ or ‘going towards’ directions or alternative north).
The figure below shows the current data derived from a measuring campaign, where the velocities were measured at two different depths (visualised by the black and red arrows, respectively). The stippled line indicates the sailing path of the vessel performing the measurements.
It is also possible to illustrate the measuering campaing in time if the data is saved within a time varying dfs1 file. An example is shown in the animation below.
