Hello, everybody. I have some images in TIFF format created in Photoshop. Also, I have georeferncing for each file in txt. If I'm working with BMP files, then i have no problems - I can use this command line for example gdal_translate -co COMPRESS=LZW -co JPEG_QUALITY=100 -a_srs "+proj=utm +zone=37 +datum=WGS84" "input.bmp" "output.tiff" Also I have created additional input.bpw file 2.00 0.00 0.00 -2.00 395276.00 6206467.00 I don't know the reason, but gdal_translate doesn't generate georeferencing without this input.bpw file.
Alternatively, you can use the -a_ullr option of gdal_translate.
But then I've tried to convert tiff without georeferencing 2 tiff with georeferencing using next command line gdal_translate -co COMPRESS=LZW -co JPEG_QUALITY=100 -a_srs "+proj=utm +zone=37 +datum=WGS84" "input.tiff" "output.tiff" Unfortunately, it doesn't work. It looks like gdal_translate is taking reference information from input TIFF and obviously there is nothing, because it was created in Photoshop. If I'm using TIFF created in GlobalMapper with georeferencing, then all works fine. How to solve this poblem?
You can use the -a_ullr option of gdal_translate, or create a .tfw file as you did for BMP files.
