Can I convert a US Topo from GeoPDF to GeoTIFF format?
Yes, it is possible to convert GeoPDF to GeoTIFF, but all the methods we know of have some drawbacks, particularly for layered PDFs like US Topo maps. Two methods for separating US Topo layers and reformatting as GeoTIFF are documented in a paper. GeoTIFF reformat for maps in the Historical Topographic Map Collection (HTMC) is also discussed. This paper is revised at irregular intervals; interested users are encouraged to check the link in this FAQ periodically for updates.
