-------- Original Message -------- Subject: USGS 15 minute digital topo index Date: Wed, 11 Jul 2012 08:15:29 -0700 From: Barbara Carroll <[log in to unmask]> To: <[log in to unmask]> CC: Barbara Carroll <[log in to unmask]> I’m trying to find a digital index for the USGS 15’ topo sheets. I’ve been able to find .shp files for the 7.5, 100, and 250 series, but no one seems to know where to find something for the 15’ series. Does anyone have any ideas that I could track down? I certainly don’t want to recreate something that is already in existence.
