I have a netcdf containing the Lon/Lat components of winds and currents

so far I only found a way to do this for point shapefiles, but my data
is composed of two rasters. any suggestions would be greatly
appreciated.
Hi Ron,
Do you need to do this within the Mapserver CGI environment or can you use
Mapscript to generate your images? If you can use mapscript, you can
write your own logic to figure out the rotation values based on the
components.
If you are stuck without mapscript, you could use another tool to add a
rotation variable to your NetCDF file and then directly use it in your
mapfile for symbol rotation (I believe this is now supported in 5.2.0)...
Others on this list may have more clever ideas.
