I've used GDAL tools for several other operations on GeoTIFFs.
There is lots of information on how to splice geotiffsGeoTIFFs into pgwPGW world files and images, but I haventhaven't found ANY documentation on how to properly CREATE a geotifGeoTIFF from an image and and a worldfileworld file (plus CRS format info).
This can be done by loading a layer in QGIS and exporting it as GeoTIFF, but need to use the GDAL commandlinecommand line directly for batch conversions.
I've found one somewhat related question, which use world files as input.
GDAL rotate DEM But despite GDAL created the file without showing errors, the file was unreadeableunreadable.
gdal_translate -of GTiff -co profile=baseline -co tfw=yes geotiff.tif baseline.tif This also lead to an unreadeableunreadable file.
gdal_translate -of GTiff -co COMPRESS=JPEG -co tfw=yes -a_srs EPSG:3857 geotiff.tif baseline.tif
