When I open this .pdf file, the map looks like a stack of .shp's (polylines, points and polygons) and it opens slowly. I think it was created by using AutoCAD or a similar software. I whant to import and open this map in a GIS software, to edits some elements of the map. its depend on what kind of PDF , if you got raster PDF, then, digitize or using raster to vector converter will be the best P.S. : the .pdf file contains a map of a city, an urban planning map (streets, residential spaces, green area, roads, and other urban elements). It looks like a stack of .shp's but it has no geographic coordinate system, becouse it was made in AutoCAD and then exported as .pdf file. So, if I will manage to bring this in ArcGIS , I will have to find a way to georeference the map. only with a geopdf you can restore all the vectors when you import the file under illustrator (and you need the last edition of mapublisher)... I suggest you to save the pdf file to an image, try to manually georeference the image , then you can import the file in arcgis... I was also considered to convert the .pdf to another format like a .jpeg or .tiff and then using image-to-image to georeference this image to a basemap in ArcGIS. But i read somewhere that the conversion of the .pdf map to a jpeg raster will lose some informations due to low resolution of the .jpeg format. It's exactly like Team_Evil said: if it's not a geopdf, nor a pdf version that keeps some editing properties (like Photoschop and probably many others), than you can forget a straight conversion to vector features. And agian confirming Team_Evil: if it's just a 'normal' pdf, you will have to save it as an image, georeference it an then import it in a GIS to convert it from raster to vector. But: you must also consider the original quality of the pdf. If you zoom in, are pixel transitions discrete or are they blurred (due to image compression)? If you succeed in doing this, I hope you have a georeferenced basemap of good quality, because otherwise the finally resulting GIS layer is not very useful. But I guess you know that 1. Make use of Corel to select extracted features. By the way, delete unnecessary things such as text, symbols and some other labels. Source.
