Display data from HF radar (speed and direction of ocean surface currents)

[MarcoAlbaETT]

Hi,
I've data from HF Radar (speed and direction of ocean surface currents) where currents are stored with two variables:

• EWCT (West-east current component)
• NSCT (South-north current component)
  I've tried to configure a dataset in order to display something like:
  

without success.

Data are from OpenDAP like
https://data-erddap.emodnet-physics.eu/erddap/griddap/HFR_EUSKOOS_Total_NRT
https://data-erddap.emodnet-physics.eu/erddap/griddap/HFR_DELTAEBRO_Total
(these are ERDDAP datasets)

Can anyone help me configuring these datasets (if possible)?

Thanks

Marco

In principle ADAGUC can display layers for directional data with arrows.
This can be achieved by configuring a layer with 2 elelements, in this case EWCT and NSCT nad using a vector plotting style.
However the vector plotting code is designed for atmospheric currents and displays only a dot for current speeds beneath 1 m/s. In the atmosphere such low wind speeds are rated as non-relevant.
Unfortunately ocean currents are very often less strong than 1 m/s, so no useful display can be generated by ADAGUC at the moment.
We might need to do some code adaptations if we want to support this.

Thanks for the clarification!
