Hi all,
Could we clarify the situation for ecw and Mrsid
formats in QGIS? (and perhaps put a note
somewhere in the qgis web pages).
I think that not being
able to read these formats is a major drawback
in practice. At least in Spain, a lot of public
available raster layers are in these formats.
Also, for example, the imagery at
https://zulu.ssc.nasa.gov/mrsid/
(I know the original landsat images for those
are available in not compressed formats, but
that site is very convenient for many people)
If there is a compiled version of gdal including
support for these formats, why QGIS cannot? In any
case, is there any workaround so that users can get
to have ecw/Mrsid support out of their compiled version?
Perhaps through a plugin?
I really think that the final QGIS1.0 should be able to read in
those formats, somehow. This is probably seen as a minor concern for
developers, but a significant problem for users.

I think the problem doesn't rely on what the dev-community want to do, but
on what we can do. MrSID and ECW licenses seem to be incompatible with the
GPL.
I'm not a license expert, so I cannot judge on that, but some time ago I
deeply discussed with license experts about that, and their response was
that "MrSID and ECW licenses are NOT GPL compliant".
I'm only a code and packaging developer, and it's not task to decide about
such things, but if the PSC members will tell me to add those format
supports into QGIS, I'll try to do that (I'll need to apply some tricks to
compile them with MinGW, but I'll try).
Regards,
Marco Pasetti
