[gdal-dev] is there a way to concatenate the band in raster file name

This feature would have to be driver-specific, so adding it to netcdf
would not benefit other drivers (in fact not all of them support

Some time ago there was a discussion about standardizing the
driver:filename syntax , it seems to have stalled. It could be a nice
addition to have the option band=<band_no> in there.


Would it be worth it allowing to select multiple bands (by range or
list) such as NETCDF:file.nc:var:1-2,4
There is a similar request already for selecting multiple bands:
