[gradsusr] Streamlines

[jenny pistoia]

Hello GraDS community.

In the framework of TESSA project( http://www.sea-conditions.com/ ),
CMCC (European Center for the climate change) is collaborating with
other organizations in order to provide the most complete ocean and
weather forecasting system for the Mediterranean Sea.

As part of this service, we want to use the class stream for the sea
surface current representation.

As you can see, when you zoom on the image, the streams seems to be
too much aggregate on the same streamline, and GraDS  neglects any
modification in the value plotted. For example if we use d u,v or d
u*0.1;v*0.1 we have the same graphic.

Do you know, if it exists, a way in order to choose the time
integration (like in other visualization program), in order to obtain
a piecewise streamlines?

I am looking for any advice to understand this feature.

Thanks in advance for you time and collaboration.
