What is a "Digital Map–Beta?"

"Digital Map–Beta" refers to a preliminary version of the US Topo map series.  About 15,000 were published in 2009 as a start-up exercise for the US Topo program, to implement and test product layout and production systems. They were basic orthoimage maps with limited linework or annotation; most significantly, they did not include contours and hydrography. 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.
