Hi Jon,
sorry for being dense, i'm a complete newbie to thredds. Are you
suggesting that the variables in the NetCDF file need to be eastward_x
and northward_x, and that thredds will recognise them as potential
vectors and give me a 'virtual' variable x i can plot ?
currently my data has 'U10' and 'V10' (as well as 'U' and 'V' with
height dimensions), so do i need to point northward_ etc prefixes to
them somehow ?
cheers,
-i

Hi Ivan,
I believe the facility to plot vectors is available in the latest TDS, unless
Ethan can correct me? (Contour plotting is still not implemented in TDS or
standalone ncWMS.)
All you have to do is to use paired standard_names of "eastward_" and
"northward_", e.g.
eastward_sea_water_velocity
northward_sea_water_velocity
and a vector layer called sea_water_velocity will be automatically created.
The default style for this layer will be a colour plot of the magnitude of the
field overlain with basic vector arrows (not wind barbs).
Hope this works for you - let me know if not.
Jon

Hi there,
I'm interested in getting 'vector-like' NetCDF rendering via the Thredds
WMS connector.. for making contour / wind direction maps.
In searching the archives i see that my question has been answered here:
http://www.unidata.ucar.edu/mailing_lists/archives/thredds/2009/msg00151.html
in that i can't at this stage, as the VECTOR style isn't implemented. I
was wondering if there is an update on this functionality since then, or
if anyone has any advice in implementing this type of functionality in
some other way.. hopefully with minimal pre-processing of the NetCDF
file beforehand.
cheers,
-ivan
