[gdal-dev] Ticket 3786

[Sjur Kolberg]

Hello,

Has anyone looked into ticket 3786 concerning the Idrisi driver?

The driver rejects the flag value (and inserts a hard-coded -9999 instead) unless the flag value is followed by a flag definition.

IMHO, this is not necessary, it would be better to accept the flag value if it is numeric, maybe even to insert "missing data" as a default flag definition.

The flag definition, when properly defined, is usually "Missing data", "Background", or something similar.
The flag value can be "none" and still satisfy the IDRISI file format.

Admittedly, the IDRISI software itself doesn't honor the flag value, so it is not obvious what to require.

The ticket includes a proposed change.

Best regards,
Sjur Kolberg :-)
