[gdal-dev] WCS driver

Yes, although in the WCS case, a coverage can have several bands, and thus using the band 
mechanism to reflect the N>2 dimensions can become confusing.

The only clean solution to that would be to have a true multidimensional raster support at 
the GDAL API level, but that's a rather involved effort.

I guess HDF5, as it is really close to netCDF.

GRIB could potentially be used to have time-varying raster, although, from what I saw, 
generally you put instead different variables for the same forecast time in the same file. But 
technically you couldx just concatenate any amount of GRIB messages into a single file and 
this will be seen as a multi-band raster by GDAL.
