[Qgis-user] Projections of Landsat

[Roi Granot]

Hi All,

I'm loading Landsat raster image (.tif) and trying to combine it with  
maps I created using GMT (.grd). What's the best way to do this?
I tried to first change the Landsat projection to mercator (the  
projection I used in GMT) - but the conversion didn't work fine.
Also, how can I get rid of the black area surrounding the oblique  
Landsat scene (which is filling the image where no data exist) so that  
I'll be able to see the background?

Many questions indeed!

Thanks,
Roi
