I have a lot of tif files (ortho imagery that came with Lidar data). Each tile has a .tif and .tfw but the world files (.tfw) have line 5 and 6 as numbers that aren't what I would expect as I was expecting the files to be in UTM ZONE 10.
Is there anything I am missing that usually comes with Ortho Imagery / Lidar? Or do I need to contact the supplier and ask them to re-export as a geo-referenced file. Or maybe this is just coordinates on a local site datum and that is it.
Below is an example of on the of the world files. The list number is the line number.
I guess the question is can you have ortho-rectified imagery on a local site datum? I thought maybe it would have to be real-world coordinates?
