netCDF in a mapfile

[Tony Jolibois]

          Hi all,

I try to display  netCDF file with the GDAL driver, but no succeed.

The gdalinfo give a good response, but I don't know how I can specifie
my variable and the depth for the layer in the mapfile (it is a 3
dimension variable).
Can anyone help me ?

Thanks in advance,
Tony

gdal from CVS today
mapserver 4.4.1
on linux AS

gdalinfo :
Driver: netCDF/network Common Data Format
Size is 8, 129
Coordinate System is `'
Origin = (0.000000,0.000000)
Pixel Size = (1.00000000,1.00000000)
Corner Coordinates:
Upper Left  (   0.0000000,   0.0000000)
Lower Left  (       0.000,     129.000)
Upper Right (   8.0000000,   0.0000000)

The header of the netCDF is like this :
