However, my aim is a bit different here: I have a few hundred TIFF files that have formerly been GeoTIFFs. I batch edited all of them in Photoshop so they lost their GeoTIFF header.
I'm still having the respective TFW file for each of them. Is there a way to re-attach the information from the TFW file to the TIFFs to create GeoTIFFs WITHOUT having to re-write all the GeoTIFFs again? (like GDAL does with gdal_translate -of GTiff input.tif ouput.tif).
I'm pretty sure I've seen a tool a few years ago that can simple re-attach the headers from the TFW files to Tiffs to create GeoTIFFs of them, I simply can't find it anymore.
