Global Mapper v25.0

Adding frojection info to Tiff files.

I'm trying to add projection information to tiff files that have tfw's and I was wondering if anyone had a solution for this? I want to just add the projection in a batch without having to output the tiff files again.


  • You can batch process your existing tifs and export them back out again with the projection embedded in the header (and it sounds like you know this already), but I'm pretty sure there's not an option to just update the header in existing files without re-exporting. Not in global mapper at least. That sounds like a custom python solution to me.
