Has anyone out there tried cleaning up a @USGS historic quad as a raster file? I'd like to do some editing, but I'm surprised that the TIFF files I find at <a href="https://ngmdb.usgs.gov/topoview/">https://ngmdb.usgs.gov/topoview/</a> are only 300 dpi and JPEG compressed.

@USGS I'm surprised, since this publication: https://pubs.usgs.gov/tm/11b03/ says that there should be uncompressed TIFF files available at 400 or 600 dpi. Perhaps I have just not found them yet?
