Apparently the format of the latest USGS GEOPDFs has changed (they refer to them as GEOSPATIAL PDFs instead of GEOPDFs). Would a newer GDAL package help? I'm still using the GISInternals package I downloaded from the Transdem site.
Can you point me to a map sheet that has these issues? I will probably have to analyse this in debug mode. It's possible that they switched to a different coordinate system, one that TransDEM does not recognize. For the margins, or neat-line as they call it, that took me completely by surprise when I discovered this feature in USGS maps. I didn't even know it existed. But it's optional. And I haven't seen it in any GeoPDF map published by other agencies.
In the meantime you can try a newer GDAL build, but I have my doubts. Anyway, that build must include the GeoPDF library.
