Hi All,

I'm trying to display a geoTiff file of slightly less than a gigabyte, but
it's not rendering. My TIFF file is in RGB. Do I understand correctly that
RGB colourspace is not supported for TIFFs? Is it possible to display a TIFF
in colour?

The reason I'm using TIFF is that I can't compress it to an ECW, due to the
filesize being over 500MB. I'm having difficulties finding a freeware
program that can convert TIFF to ECW (any ideas?)

Regards,

Jacob
