I have a map over Sweden with plenty of data represented as circles of various sizes. The map is saved as PDF from Illustrator, fully editable. I wonder if there is any way I could get these circles into Tilemill so that I can make a searchable georeferenced map? I don't know the projection but I would guess WGS84 or SWEREF99.
One way that comes to mind is to extrakt the geodata from a geotiff of Sweden (if I find one with the same projection), place PDF-map on top of the geotiff in Illustrator/Photoshop and then use gdal to insert the geodata again.
Any ideas if this is a good way, or if there are better methods?
