[Qgis-user] Stacking Landsat Bands

[Jonathan Moules]

Thanks for the replies. Lots of options, useful to know.

@Andreas - My issue was that my bands were separate images, I don't believe I can visualise them in a RGB-ish manner without first stacking into a single image.

Cheers,
Jonathan

Hi,

If it is just for display you can display the landsat image in QGIS right away. You can freely assign selected bands to rgb channels in the "Style" tab of QGIS. So no need to recalculate images ...
