[Talk-us] NHD data extract

[Ben Supnik]

Hi Ian,

Where on the OSM servers is the current NHD data, and in what format?  I 
didn't see it referenced in the wiki work-flow.

I am looking at this now.  Some of the polygonal lakes definitely do 
contain reach codes, others contain NULL.  From what I can tell, there 
are fcodes that indicate that there is no reach code (or any meta data).

For the polygonal "area" data (which includes large rivers) there are 
indeed no reach codes. :-(

cheers
