I have a PDF containing a region of Baltimore city that contains lots of polygons in it. You can download it from here:
I also have a kmz file, containing each part of Baltimore city, you can download it here:
All I want to do is to open the kmz file in QGIS, then import the pdf file into qgis as background and then select the city regions with mouse and based on the color of the region in the PDF file, edit the attributes of the kmz file and after all I want to export it as an shape file. How am I able to import the pdf file as a background image and fit it to city regions in order to be able to select the regions regarding the background image?
