How to fix a GeoTIFF that has an invalid NO DATA value
When importing a GeoTIFF into a project that you are editing, it can occur that you will receive the following error:
This error means that the metadata of the GeoTIFF for the NO_DATA value was written in the ','-number notation, instead of the expected '.'-number notation.
It is possible to fix the metadata of a GeoTIFF. You can download the free exiftool program to automatically adjust the NO_DATA-metadata.
Download url exiftool: [1]
Once downloaded, extract the file
Next, you can create a command file that automatically adjust the NO_DATA to a valid value: -3.4028229999999999999e+038 (-Infinity)
exiftool.exe nodata_tiff_comma.tiff "-GDALNoData=-3.4028229999999999999e+038"
C:\Users\TYGRON\Downloads\downloadtool\exiftool-12.65\exiftool.exe %1 -GDALNoData=-3.4028229999999999999e+038
pause
C:\Users\TYGRON\Downloads\downloadtool\exiftool-12.65\exiftool.exe %1
pause
Notes
- You can also adjust the NO_DATA value to an other value than -Infinity, for example to -999.
