Is there anywhere I can download USGS Topo TIFS? The new ones? The USGS site just gives me GeoPDF and their web service restricts the scale you can see them at. Edit : I am looking for the the new USGS Topo maps (c 2012).

GDAL can read the pdf and make it an image format. http://www.gdal.org/frmt_pdf.html GlobalMapper will do the same.
The national map allows you to download the imagery (USTOPO uses NAIP). http://viewer.nationalmap.gov/viewer/

On the page it states "GDAL supports reading Geospatial PDF documents, by extracting georeferencing information and rasterizing the data." So my assumption is yes.– mikeCommented Jul 16, 2013 at 20:58
The Libre Map Project (through archive.org) has the digital DRGs (tiffs) for all 50 states for free. Only thing is, they are still collared. Go to the Data section for a state and there is a link on the top for the DRGS, here is Ohio for example.

Not the same product the OP is asking for. Good source of data though.– mikeCommented Jul 10, 2013 at 17:05
ESRI offers the seamless USA Topographic base map, freely through a Map Service named USA_Topo_Maps. As you zoom-in, more detailed maps display. The 7.5 minute quads or 1:24000 scale are the most detailed.
