I am trying to extract and georeference the orange polygons/lines from this PDF file of the city of São Paulo, in Brazil.
To do so, I am mostly trying to follow what was discussed in another question, but none of the proposed solutions are working for me.
I tried using Adobe Illustrator to extract those and export to a DXF archive, but the QGIS step is curbing my advances. I am working in EPSG 32723. My first attempt was to use the affine transformation, but the imported shapefile could not pass through: all polygons had invalid geometries.
The attempt to use JOSM also failed. I cannot process the output from downloading São Paulo's data.
Is there another path to extract those vector objects?
