This question already has an answer here:
I have this pdf file that contains a specific borough of my city, Montreal, with a polygon inside it. Link to pdf file: PDF FILE
The jpeg image once exported from the pdf file is the following
I am trying to extract the red polygon and georeference it.
I have tried using QGIS to open the image file and then manually add coordinate points to specific portion, but it seems tedious and long as I have around 90 different pdf file that I aim to georeference.
Is there an easier way such as taking an actual map of montreal and overlay this map on top of the previous one, and then automatically georeference it?
I don't know if it can help you but the actual pdf file is a vector, when I opened it using illustrator I was able to check or uncheck the red portion.
The ultimate goal is to transform this red polygon into a geojson file. I don't mind doing it manually if theres an efficient way but I would be even happier If there's was some way to automate this through a script.
I have been looking over the past week on the internet for georeference tutorials but most of them are for raster images and do not take in account pdf file (vectorized), I mean in theory, in my opinion it seems possible to compare 2 vector file, mine and lets say the whole vector file of montreal and then georeference it automatically.
