[gdal-dev] Issue with sub-dataset suffix

[Simon Eves]

OK, I get it now.

So the "filename" to open is the exact SUBDATASET_X_NAME string from the
metadata. It seems you can safely omit the quotes (at least in the case of
this file), which is perhaps part of my confusion.

Sorry, that makes sense in hindsight.

Thank you, as ever, for your prompt assistance!

Simon
