I'm a noob at this, but have decided to try to follow Oz's excellent tutorial and make a topo of WA state. I have begun downloading and processing all the NED files. Hopefully will be finished by the end of the week and can get started on the NHD files.
How long does it usually take to start getting NHD files after the request is submitted? I submitted some requests 2 days ago and have yet to hear anything.
