In my line of work, I need to be able to georeference PDFs in ArcGIS Pro. We already have significant library of all the PDFs that we need (more that 100,000). For us it is a waste of space and money to convert all of these (and future) PDFs in TIFF or JPEG files.We will need additional space to store them. We have other programs that are using the same PDFs and will not work with other format of raster files. In other words, we need to be able to georeference PDF.
