We often find maps in pdf, which have been generated from a mapping program, therefore vector, and we want to import them into ArcMap or AutoCAD. It is curious that since pdf is a well-known format, to which everyone exports and which now even has georeference properties, none of the popular mapping programs has developed the function of importing even the ones that it generated.
Here I present two alternatives.
1 Through a graphic design program
This can work either Adobe Illustrator or Freehand.
The output is to import them from the design program, then export them to dxf that can be opened by any CAD / GIS program, of course you have to understand that the dxf alone has no georeference
2. Through AideCAD
This is A program which converts vectors from pdf to dxf format
Unfortunately both are payment programs although there are trial versions that can get you out of a hurry.
3 Through another solution
I remember seeing another more practical solution, but now I don't remember it; We leave the space for someone to tell us if there is another alternative ... then we finish the post.
The first one has already appeared:
