I have files with the u resp v components of regularly spaced wind
vectors (ASCII arrays). How can I construct flow vectors.
There is no direct ASCII grid reader in the IDV, but it is
on our list of things to do. The big problem is deciding on
a format. The underlying VisAD library has a method for reading
ASCII grids and we are looking at using that as well as a
netCDF-Java IOSP.
There are a couple of options:
- use the VisAD text reader and then try to display the
resulting data structure using the Any Field formula and
selecting a flow display.
- use the GEON-IDV ASCII->netCDF converter described at:

Stu Wier might want to chime in on this since he's the one
who developed it.
Can you send a sample file to support-idv?
