Folks,
I have been working with netCDF files recently, and I have been
bothered by the lack of a decent way to browse the contents of
these files. I've found decent software to read the variables
out of these files, but you have to know the names of the
variables you want to read, and I often don't. I've tried
using the HDF_BROWSER, but that interface is god-awful
ugly, not to mention non-intuitive, and I don't like it.
So I wrote my own netCDF Browser. All you do is pass it
the name of the file and it can parse all the data and
metadata in the file and it will give you a graphical
view of it. Select a variable you want to read, and the
browser will read the variable and put it into a variable
at the main IDL level for you.
Most of the functionality is built into a NCDF_DATA
object. This gives the user great flexibility and functionality
to work with netCDF files. But I think most users will
use the NCDF_BROWSER front end. This is just an IDL procedure
that takes the name of a netCDF file. It does everything else,
including cleanup up after itself.
I have some ideas for cosmetic updates, but before I implement
them, I thought I would try to get some feedback to see if the
browser works with everyone's netCDF files. They have worked
with all I've tried, but I haven't subjected them to newbie
programming pressure yet. :-)
If you are interested, you can find all the Coyote programs
you need here:
http://www.dfanning.com/programs/ncdf_browser.zip
To run the basic program, just pass the filename of a netCDF
file to the program, like this:
IDL> nCDF_BROWSER, file
Always interested in your feedback.
Cheers,
David

Hi David,
nice to see a new netCDF tool ;)
just an info
netCDF 4.0 will be compatible to hdf (and I hope it doesn't take as long
as to get the change from 2.4 to 3.x in idl.)
cheers
