Question: USGS has embarked on digitizing historic topographic maps for all US states.(http://nationalmap.gov/historical/) Finished maps are in GeoPDF format, which as far as I can tell is not useable directly in ArcGIS 10. Opening GeoPDF in Acrobat Reader or Professional with TerraGo toolbar works fine but has limitations. I can “save as” out of Acrobat Professional as either a TIFF or JPEG/JPEG2000, but no world file is created and resulting files are not georeferenced. It is possible, of course, to georeference the files in Arc, but I would like to find a way to work with these files directly in Arc without the additional steps of file conversion and georeferencing. Is this possible? and if not please add it to the list of functions that should be addressed. This is a huge and valuable dataset that should be accessible to Arc users.
Thanks & Happy Holidays
Answer: You cannot currently view GeoPDF in ArcMap. You might like to add your support to this functionality at the Ideas site entry View GeoPDF files in ArcMap.
