[gdal-dev] gdalbuildvrt problem with heterogenous band characteristics

[Chaitanya kumar CH]

Casper,

You can edit the vrt file in a text editor. Just make a copy of the
elements of one file and change them according to the fourth file. You can
refer to the VRT tutorial[1] if you have any doubts.

Can you provide the full gdalinfo report of the two files?
