How can I clip the exact same area out of multiple satellite images ( multiple bands)? I am working on a remote sensing project and only need a certain island but the images show much more.
It might be faster to use GDAL instead of QGIS even for a couple of images but especially if you will need to do clipping frequently for your area. Use the -projwin option
http://www.gdal.org/gdal_translate.html The order of coordinates [-projwin ulx uly lrx lry] may feel odd at the beginning.
