[gdal-dev] Reading Layers In USGS Geospatial Topo Files:

[Laurențiu Nicola]

Hi Carl,

I randomly found https://opengislab.com/blog/tag/GeoPDF+to+GeoTiff which seems helpful, but I have no experience with those USGS PDFs. I tried to build one with their app, but it will take a day or so for them to send it.
