Convert GeoPDF Maps to GeoTIFF with GDAL

The first thought a GIS Professional gets on seeing a GeoPDF map is how to get it into GIS application. This particularly would be the case in US where USGS maps are all provided as high quality GeoPDFs and the analyst would want to derive maximum information from the maps.
A good way to get the map into a GIS application would be in the form of high resolution GeoTIFF. USGS National Map suggests using Global Mapper for the purpose [PDF]. When a similar requirement came to me I tried the operation withtrial version of Global Mapper.
