lost coordinate after steganography
显示 更早的评论
why after exporting the .tiff steganography results the geometry correction disappears? so I have a tiff that already has coordinates, when the steganography process is finished the coordinates disappear.
please help thank you

What geometry correction? What coordinates? How did you write the file?

As far as I know, any sort of time/date/geolocation metadata is not stored in the raster image. It's stored in the file header. You need to write all that info into the new file. If you don't copy it, it won't be there.
How you do that depends on what sort of TIFF it is.
I'm not really familiar with geoTIFF, and I have an older version without some of the newer tools, so you'll have to look at what metadata your original file has and figure out how to set those tags in the new file.
