I have in QGIS a higher quality GeoTIFF overlayed on a larger, lower quality GeoTIFF. I reprojected one raster into the coordinate system of the other.
How can I export these to a single GeoTIFF while retaining the resolution of the high quality raster?
I've tried using the Merge tool (with no data set to 255 to remove whitespace) but get an error at 50%: "Illegal band #." The resulting layer is low quality and much brighter.
I also tried using Build Virtual Raster, but the resulting layer turns red and green (with "Place each input file into separate band" checked). Without it checked, the high quality raster doesn't show up in the new layer.
The high quality raster has 3 bands and the lower quality raster has 4 bands. There is no information by the 4th band though
