[Qgis-user] 2019 USGS 7.5min topo sheets

[Mike Flannigan]

Much to my surprise I think you are correct.
QGIS can open a TIF file (and a zipped TIF file),
but I can't get a GeoPDF to open in QGIS.  If I
convert the GeoPDF to a TIF with GDAL, it still
will not open and gives error "Missing Codec".

Very surprising.  I know from past experience that
Global Mapper v6.04 will view TIF files that have
been converted from GeoPDF via GDAL.

I would try downloading the map in a different format. I don't know what site you are using, but the USGS TopoView site (https://ngmdb.usgs.gov/topoview/) has the maps available as JPEG, KMZ, GeoTIFF, and GeoPDF. I would recommend the GeoTIFF format as all versions of QGIS support that.
