What do I have to do to convert geopdf to tiff? I'm looking at historical topo maps downloaded from the text search app (USGS US Topo and Historical Topographic Map Collection )

 

This tool claims to convert geopdfs, but after loading the USGS geopdfs I get the above error and this:

 

Description

The GeoPDF file contains a map section with unsupported structure, which results in an ungeoreferenced TIFF.

 

 

Solution

Georeference the TIFF manually.

 

Am I getting the wrong GeoPDFs?  Are there multiple geopdf formats or something?

 

Thanks!
