Can you georeference a PDF?

Answer. No, it is not possible to georeference a PDF file directly in ArcMap. ArcGIS does not support PDF as an input format. The PDF file must be converted to a supported raster format, such as JPEG or TIFF, and be added to ArcMap before georeferencing.

How do I georeference a PDF in Global Mapper?

Open dataset

1. Load non-georeferenced map into Global Mapper (File-> Open datasets).

What is Georeferencing PDF?

Georeferencing is a tool which allows for digitized copies of maps to be imported into ArcMap, and then linked to certain features to transform the map to a real-world coordinate system, so that information from the paper map can be extracted to vector data with a spatial reference.
