How can I convert a PDF map into vector data?

Question

I have a PDF map that I would like to convert to GIS data. The original map was generated using GIS, however, the data files have disappeared. Without going through all of the original analysis, is it possible to generate polygons from the PDF file? TIA.

No. The source files are gone. Someone would have to run the analyses again which might happen anyway. Not to worry. You’ve answered my question.

Cheers.

Be aware that you will lose precision in that process. Is it possible to obtain the source files recreate the polygones?

I think I’ll just have to convert it to a jpg or tiff, georeference it and digitize the layer I want (boundaries representing wine regions). It is not a geopdf.
