[GRASSLIST:8212] Re: MrSID and incorporating the .sdw info into resulting GeoTiff.

[William Kyngesburye]

Even easier - use the -wf option in mrsiddecode:

mrsiddecode -i FILE.sid -o FILE.tif -wf -of tifg

And if the mrsiddecode geotif output is broken like this, why use  
geotif at all at this step?  Just drop the '-of tifg' option and let  
gdal_translate create the geotif.

All generalizations are dangerous, even this one.
