You can find the ncWMS code that THREDDS is using here:
https://github.com/Unidata/ncWMS
Specifically, vectors are created here:
https://github.com/Unidata/ncWMS/blob/master/src/java/uk/ac/rdg/resc/ncwms/graphics/ImageProducer.java#L185
And the classes that actually do the drawing:
https://github.com/Unidata/ncWMS/blob/master/src/java/uk/ac/rdg/resc/ncwms/graphics/VectorFactory.java
https://github.com/Unidata/ncWMS/blob/master/src/java/uk/ac/rdg/resc/ncwms/graphics/BarbFactory.java
In your case, you would need to apply an scale transform on the drawn object
based on magnitude.
For building NcWMS for TDS, there is an ANT script here:
https://github.com/Unidata/ncWMS/blob/master/buildTds.xml with a target of
“buildNcwmsJar”.

Hi Kyle, thanks for getting back to me..
I'm sorry i think i wasn't clear.. i'm aware there are 'new' vector styles in
the current TDS, fancyvec, windbarb etc.. (these are excellent and we use them
already).. what I would like to do is add a scaling notion to them.. so the
arrows can indicate direction as well as magnitude, and not just through colour
but with their size.. as per a traditional 'quiver' plot.. e.g.:
http://matplotlib.org/examples/pylab_examples/quiver_demo.html
for this i'm expecting to find where the arrow is created and scale it, and
include that modified version of ncwms in our thredds WAR file.
apologies if i misunderstood your email or am on the wrong track here..

Hi Ivan –
The new vector styles are already available in the newest TDS.
I’ve attached an image showing the vector style options. In addition to the
attached, there is also the “barb” style.
Here is an example:
http://64.9.200.113:8080/thredds/catalog/glos/glcfs/ontario/fcfmrc-3d/catalog.html?dataset=glos/glcfs/ontario/fcfmrc-3d/Lake_Ontario_-_3D_best.ncd
If you take a look at the WMS service, the new vector styles are advertised.
Hope this helps,
Kyle

Subject: [thredds] ncwms customisation from TDS source..
Hi there,
I would like to bite the bullet and have a shot at building a new vector style
in the ncwms inside TDS capable of presenting magnitude, for example scaling
the currently existing 'stumpvec' style to show wind/current strength etc.
i've downloaded the source from github and can build the WAR, and am now in the
process of finding where the relevant code to modify is.
from what i can see the ncwms component is not built when you build TDS, it
seems the file ncwms-1.0.tds.4.3.20130116.1130.jar is downloaded during the
build process and used directly.
At the risk of asking a very basic question, how do i go about building a new
(compiled) ncwms.jar, compatible with the built TDS WAR file ?
and secondly, i have searched for where the 'new' vector styles are defined
('fancyvec', 'stumpvec' etc).. but i cannot find them. I have found the
original vector style drawing code here:
\thredds-master\lib\release\source\ncwms\uk\ac\rdg\resc\ncwms\graphics\ImageProducer.java
but not the new arrow styles.
any help with those two points would be much appreciated,
thanks,
-ivan
