"Digital Map–Beta" refers to a preliminary version of the US Topo map series. About 15,000 of these were published in 2009, and were basic orthoimage maps with no contours and little other linework or annotation. In 2012 all instances of "Digital Map–Beta" were replaced with US Topo contour maps and the "Digital Map–Beta" maps were removed from USGS download interfaces.
